Question 1Coding Guidelines and Regulatory Compliance

Under the ICD-10-CM Official Guidelines, a condition documented as "probable" in an outpatient setting should be coded as:

  1. The probable condition as if confirmed
  2. The probable condition with a history code added
  3. A query to the provider before any code is assigned
  4. The sign or symptom that prompted the visit Correct answer.

Explanation

In outpatient coding, diagnoses documented as probable, suspected, or rule-out are not coded as confirmed. Instead, the coding professional reports the signs or symptoms that prompted the encounter. Inpatient guidelines differ and do permit coding of probable conditions.

Question 2Coding Guidelines and Regulatory Compliance

A patient presents with chest pain and the provider documents "rule out myocardial infarction." In the outpatient setting, which code is appropriately assigned?

  1. Chest pain Correct answer.
  2. Acute myocardial infarction
  3. Encounter for observation for suspected myocardial infarction
  4. Personal history of myocardial infarction

Explanation

When a diagnosis is documented as rule out or suspected in the outpatient setting, the condition is not coded. The sign or symptom that prompted the visit, here chest pain, is reported instead.

Question 3Coding Guidelines and Regulatory Compliance

The acronym HIPAA stands for which of the following?

  1. Health Insurance Portability and Accountability Act Correct answer.
  2. Hospital Insurance Protection and Access Act
  3. Health Insurance Privacy and Access Act
  4. Health Information Privacy and Accountability Act

Explanation

HIPAA is the Health Insurance Portability and Accountability Act, enacted in 1996. It governs privacy and security of protected health information, among other things. The other expansions alter key words and do not reflect the statute's title.

Question 4Coding Guidelines and Regulatory Compliance

Which of the following is a HIPAA identifier that must be protected under the Privacy Rule?

  1. The provider's National Provider Identifier
  2. The patient's medical record number Correct answer.
  3. The patient's city of residence
  4. The name of the treating facility

Explanation

The Privacy Rule lists 18 identifiers, including medical record numbers, that must be safeguarded. City of residence alone is not one of the listed identifiers, and provider or facility identifiers are not patient identifiers.

Question 5Coding Guidelines and Regulatory Compliance

The minimum necessary standard under HIPAA requires that covered entities:

  1. Disclose all records requested by any workforce member
  2. Obtain written authorization for every internal use
  3. Limit uses and disclosures of PHI to the least amount needed Correct answer.
  4. Retain records for a minimum of ten years

Explanation

The minimum necessary standard directs covered entities to make reasonable efforts to limit PHI to the minimum needed to accomplish the intended purpose. Certain disclosures, such as treatment, are exempt. It does not create a universal authorization requirement or a retention period.

Question 6Coding Guidelines and Regulatory Compliance

A patient requests an amendment to their medical record that the provider denies. Under HIPAA, the covered entity must:

  1. Delete the disputed information from the record
  2. Provide a timely written denial that includes the patient's right to submit a statement of disagreement Correct answer.
  3. Ignore the request if the record is accurate
  4. Charge the patient a fee for reviewing the denial

Explanation

When an amendment is denied, HIPAA requires the covered entity to provide a timely written denial and inform the patient of the right to submit a statement of disagreement. Records are not deleted, and the request cannot simply be ignored.

Question 7Coding Guidelines and Regulatory Compliance

Under the HIPAA Security Rule, which safeguard category includes access controls and audit logs?

  1. Physical safeguards
  2. Organizational safeguards
  3. Administrative safeguards
  4. Technical safeguards Correct answer.

Explanation

Technical safeguards include access controls, audit controls, integrity controls, and transmission security. Physical safeguards address facility access and device controls, while administrative safeguards cover policies and workforce training.

Question 8Coding Guidelines and Regulatory Compliance

A coder is asked to assign a code that the physician did not document because the coder believes it is clinically supported. The correct action is to:

  1. Assign the code only if a colleague agrees
  2. Query the provider for clarification and code only what is documented Correct answer.
  3. Assign the code and add a note explaining the rationale
  4. Assign the code based on clinical judgment

Explanation

Coders may not assign codes for conditions that are not documented by the provider. When documentation is unclear or incomplete, the appropriate step is to query the provider. Coding must reflect physician documentation, not coder inference.

Question 9Coding Guidelines and Regulatory Compliance

In ICD-10-CM, the "Tabular List" is best described as:

  1. A list of procedure codes
  2. A crosswalk between ICD-9 and ICD-10
  3. A numerical list of codes organized by chapter and category Correct answer.
  4. An alphabetic index of diseases

Explanation

The Tabular List presents codes in numerical order organized by chapter, with notes and conventions that govern code assignment. The Alphabetic Index is a separate lookup tool that must be verified against the Tabular List.

Question 10Coding Guidelines and Regulatory Compliance

In the ICD-10-CM Alphabetic Index, a condition listed with a bullet (•) indicates that:

  1. The condition requires an additional character
  2. The condition is not a valid code
  3. The condition is a manifestation that requires an etiology code Correct answer.
  4. The condition is excluded from coding

Explanation

A bullet in the ICD-10-CM Alphabetic Index indicates the condition is a manifestation and requires an etiology code to complete the diagnosis. The etiology code is sequenced first, followed by the manifestation code.

Question 11Coding Guidelines and Regulatory Compliance

A code in the ICD-10-CM Tabular List that appears in brackets, such as [ ] following a code title, indicates:

  1. A synonym, alternative wording, or explanatory phrase Correct answer.
  2. A non-essential modifier
  3. A required secondary code
  4. A code that should never be used

Explanation

Brackets in the Tabular List enclose synonyms, alternative wording, or explanatory phrases to clarify code meaning. They do not affect whether the code is reportable.

Question 12Coding Guidelines and Regulatory Compliance

The phrase "Code first" in an ICD-10-CM instructional note indicates that:

  1. The secondary code should be listed first
  2. The code should be omitted if another code applies
  3. The underlying condition should be sequenced before the manifestation Correct answer.
  4. The code is optional

Explanation

"Code first" notes indicate that the underlying etiology or cause should be sequenced before the manifestation code. The sequencing is mandatory when the note appears.

Question 13Coding Guidelines and Regulatory Compliance

Which organization publishes the ICD-10-CM Official Guidelines for Coding and Reporting?

  1. The four cooperating parties including CMS and CDC/NCHS Correct answer.
  2. The World Health Organization alone
  3. The American Medical Association
  4. The Joint Commission

Explanation

The ICD-10-CM Official Guidelines are developed by the four cooperating parties, which include CMS, CDC/NCHS, AHIMA, and AHA. WHO publishes ICD but not the U.S. clinical modification guidelines.

Question 14Coding Guidelines and Regulatory Compliance

Under the Privacy Rule, a covered entity may disclose protected health information for treatment, payment, and health care operations without authorization because these are:

  1. Permitted disclosures Correct answer.
  2. Marketing activities
  3. Research activities
  4. Required disclosures

Explanation

TPO disclosures are permitted without patient authorization under the Privacy Rule. They are not mandatory disclosures, and marketing and most research uses generally require separate authorization or waiver.

Question 15Coding Guidelines and Regulatory Compliance

A patient asks for a copy of their medical record. Under HIPAA, the covered entity must:

  1. Require the patient to obtain a court order
  2. Refuse the request unless the patient explains the reason
  3. Send the record to the patient's attorney only
  4. Provide access within the timeframe allowed by law and may charge a reasonable, cost-based fee Correct answer.

Explanation

HIPAA grants patients a right of access to their records and requires the covered entity to respond within the regulatory timeframe. A reasonable, cost-based fee may be charged. Patients do not need to justify their request.

Question 16Coding Guidelines and Regulatory Compliance

The principal diagnosis in the inpatient setting is defined as the condition:

  1. Most severe among all documented conditions
  2. Listed first in the physician's progress notes
  3. Chiefly responsible for occasioning the admission Correct answer.
  4. That required the most resources to treat

Explanation

The principal diagnosis is the condition established after study to be chiefly responsible for occasioning the admission. Resource consumption and note order do not define it.

Question 17Coding Guidelines and Regulatory Compliance

A patient is admitted for pneumonia and also has documented diabetes. The diabetes is addressed during the stay. How should the diabetes be reported?

  1. As an external cause code
  2. Not at all
  3. As a secondary diagnosis Correct answer.
  4. As the principal diagnosis

Explanation

Conditions that are present on admission and relevant to the encounter are reported as secondary diagnoses. The principal diagnosis remains the condition chiefly responsible for admission, here pneumonia.

Question 18Coding Guidelines and Regulatory Compliance

In ICD-10-CM, the placeholder character "X" is used to:

  1. Show that the code is a manifestation
  2. Indicate a code is invalid
  3. Fill a character position so the code meets the required length Correct answer.
  4. Indicate the code is for research only

Explanation

The placeholder X is used when a code requires a seventh character but no sixth character exists, preserving the code length and position. It does not signal invalidity or research-only use.

Question 19Coding Guidelines and Regulatory Compliance

Which of the following best describes an "external cause" code in ICD-10-CM?

  1. A code describing how and where an injury or event occurred Correct answer.
  2. A code describing a patient's occupation
  3. A code describing a complication of surgery
  4. A code describing the underlying disease process

Explanation

External cause codes identify the cause, intent, and place of occurrence of injuries and other events. They supplement the injury code and are not used to describe disease processes.

Question 20Coding Guidelines and Regulatory Compliance

A coder discovers that a previously submitted claim used an incorrect code. The most appropriate action is to:

  1. Correct the record and submit an amended or corrected claim per payer policy Correct answer.
  2. Leave the claim as submitted
  3. Delete the original documentation
  4. Wait until the next encounter to fix it

Explanation

Coding errors should be corrected in the record and communicated through the payer's correction process, such as an amended claim. Original documentation should be retained with proper amendment practices.

Question 21Coding Guidelines and Regulatory Compliance

The False Claims Act prohibits which of the following?

  1. Documenting a patient's allergies
  2. Querying a physician for clarification
  3. Requesting medical records for review
  4. Billing for services that were not provided Correct answer.

Explanation

The False Claims Act imposes liability for knowingly submitting false or fraudulent claims, including billing for services not rendered. Legitimate documentation and query practices do not violate the statute.

Question 22Coding Guidelines and Regulatory Compliance

Under the Anti-Kickback Statute, offering something of value to induce referrals for services payable by a federal health care program is:

  1. Permitted if the value is small
  2. Prohibited unless a safe harbor applies Correct answer.
  3. Permitted with patient consent
  4. Permitted only for physicians

Explanation

The Anti-Kickback Statute prohibits remuneration intended to induce referrals for federally payable services. Certain arrangements are protected only if they meet a regulatory safe harbor.

Question 23Coding Guidelines and Regulatory Compliance

A patient is seen for a laceration and the provider documents the injury as a work-related accident. To fully describe the encounter in ICD-10-CM, the coder should report:

  1. Only the external cause code
  2. The laceration code and a history code
  3. The laceration code and the external cause code Correct answer.
  4. Only the laceration code

Explanation

Injury codes should be accompanied by external cause codes to describe how and where the injury occurred. Reporting only one component leaves the encounter incompletely described.

Question 24Coding Guidelines and Regulatory Compliance

Under HIPAA, a business associate agreement is required when:

  1. A covered entity shares PHI with a vendor that performs services on its behalf Correct answer.
  2. A hospital posts a notice of privacy practices
  3. A provider discusses treatment with another provider
  4. A patient requests their own records

Explanation

A business associate agreement is required when a covered entity discloses PHI to a vendor performing functions or services on its behalf that involve PHI. Treatment disclosures and patient access requests are not business associate arrangements.

Question 25Coding Guidelines and Regulatory Compliance

A hospital's coding audit reveals a pattern of upcoding. The compliance officer's best first response is to:

  1. Terminate all coders involved immediately
  2. Conduct a root-cause review and implement corrective action and education Correct answer.
  3. Ignore the findings because audits are internal
  4. Submit a press release about the findings

Explanation

A compliance program should investigate the cause of the findings, implement corrective action, and provide education to prevent recurrence. Immediate termination without review and ignoring findings are not appropriate responses.

Question 26Coding Guidelines and Regulatory Compliance

Under the ICD-10-CM Official Guidelines for Coding and Reporting, a code that is enclosed in brackets in the Tabular List, such as [ ] following a code title, indicates:

  1. An optional code that may be added for completeness
  2. A code that is not part of the ICD-10-CM classification
  3. A code that is not required for reporting
  4. A manifestation code that must be sequenced first Correct answer.

Explanation

Brackets in the Tabular List enclose manifestation codes that are used in conjunction with an underlying etiology code. The Official Guidelines state that the manifestation code should be sequenced after the etiology code, and the brackets indicate that the code is a manifestation.

Question 27Coding Guidelines and Regulatory Compliance

A patient is admitted with acute systolic heart failure and also has chronic kidney disease stage 4. The provider documents that the heart failure is due to the kidney disease. According to ICD-10-CM guidelines, how should the codes be sequenced?

  1. Only the heart failure code
  2. Only the chronic kidney disease code
  3. Chronic kidney disease first, then heart failure Correct answer.
  4. Heart failure first, then chronic kidney disease

Explanation

When a condition is described as due to another condition, the underlying cause is coded first. Here, the heart failure is due to the kidney disease, so the chronic kidney disease is sequenced first, followed by the heart failure code.

Question 28Coding Guidelines and Regulatory Compliance

A coder is reviewing a record where the physician documented "rule out pneumonia" as the final diagnosis. According to ICD-10-CM guidelines for outpatient coding, how should this be coded?

  1. Code the symptoms or signs that prompted the visit Correct answer.
  2. Code the pneumonia with a query flag
  3. Do not code anything
  4. Code the pneumonia as confirmed

Explanation

In the outpatient setting, diagnoses documented as "rule out," "suspected," or "probable" are not coded as confirmed. Instead, code the signs or symptoms that prompted the visit until a definitive diagnosis is established.

Question 29Coding Guidelines and Regulatory Compliance

Under the HIPAA Privacy Rule, which of the following is considered protected health information (PHI)?

  1. A list of patients' room numbers without names
  2. A hospital's financial report without patient identifiers
  3. A patient's billing record that includes their diagnosis and date of birth Correct answer.
  4. A patient's name and address in a marketing database

Explanation

PHI is individually identifiable health information transmitted or maintained in any form. A billing record with diagnosis and date of birth contains identifiers and health information, thus qualifying as PHI.

Question 30Coding Guidelines and Regulatory Compliance

A covered entity experiences a breach of unsecured PHI affecting 300 individuals. Under the HIPAA Breach Notification Rule, which action is required?

  1. Notify the Secretary of HHS only if the breach involves more than 500 individuals Correct answer.
  2. Notify the affected individuals, the Secretary of HHS, and the media
  3. Notify the affected individuals and the media, but not HHS
  4. Notify only the affected individuals within 30 days

Explanation

Breaches affecting fewer than 500 individuals require notification to the Secretary of HHS within 60 days after the end of the calendar year. Breaches of 500 or more require immediate notification to HHS, media, and individuals.

Question 31Coding Guidelines and Regulatory Compliance

A physician orders a test and the coder assigns a code for a more complex test that was not performed. This is an example of:

  1. Upcoding Correct answer.
  2. Balanced billing
  3. Downcoding
  4. Unbundling

Explanation

Upcoding is assigning a code for a service that is more complex or higher paying than the service actually provided. This can be a violation of the False Claims Act.

Question 32Coding Guidelines and Regulatory Compliance

A patient is seen in the emergency department for chest pain. The physician documents "chest pain, rule out myocardial infarction." The patient is admitted to the hospital. How should the principal diagnosis be determined for the inpatient admission?

  1. The myocardial infarction is the principal diagnosis because it was suspected
  2. The principal diagnosis is the condition after study that occasioned the admission Correct answer.
  3. The principal diagnosis is always the first listed in the discharge summary
  4. The chest pain is the principal diagnosis because it was the reason for admission

Explanation

For inpatient admissions, the principal diagnosis is defined as the condition established after study to be chiefly responsible for occasioning the admission. If the myocardial infarction is ruled out, the chest pain may become the principal diagnosis if it was the reason for admission.

Question 33Coding Guidelines and Regulatory Compliance

In ICD-10-CM, a code that describes a complication of a procedure is typically found in which chapter?

  1. Chapter 18: Symptoms, signs, and abnormal clinical and laboratory findings
  2. Chapter 19: Injury, poisoning, and certain other consequences of external causes Correct answer.
  3. Chapter 20: External causes of morbidity
  4. Chapter 21: Factors influencing health status and contact with health services

Explanation

Complications of medical and surgical care are classified in Chapter 19 of ICD-10-CM, which covers injury, poisoning, and other consequences of external causes.

Question 34Coding Guidelines and Regulatory Compliance

A patient is admitted for a procedure and the coder assigns a code for a complication that was not documented by the physician but is implied by the clinical findings. What should the coder do?

  1. Report the case to the compliance officer
  2. Assign the complication code based on clinical findings
  3. Query the physician for clarification and documentation Correct answer.
  4. Assign a symptom code instead

Explanation

Coders cannot assign codes for conditions that are not documented by the provider. When clinical findings suggest a condition that is not documented, the coder should query the physician for clarification.

Question 35Coding Guidelines and Regulatory Compliance

Under the Anti-Kickback Statute, which of the following is prohibited?

  1. Waiving a copayment based on financial need
  2. Participating in a shared savings program
  3. Providing a discount to a patient for prompt payment
  4. Offering a gift card to a patient for choosing a particular home health agency Correct answer.

Explanation

The Anti-Kickback Statute prohibits offering anything of value to induce referrals for services payable by a federal healthcare program. Offering a gift card to influence a patient's choice of provider could be considered a kickback.

Question 36Coding Guidelines and Regulatory Compliance

A coder is employed by a hospital and is asked by a physician to assign a higher-level evaluation and management code to increase reimbursement. What should the coder do?

  1. Discuss the request with the patient
  2. Assign the code that is supported by the documentation Correct answer.
  3. Comply with the physician's request
  4. Report the physician to the compliance department

Explanation

Coders must assign codes based on the documentation in the medical record. Assigning a code that is not supported by documentation is fraudulent and violates coding ethics and federal law.

Question 37Coding Guidelines and Regulatory Compliance

A patient is seen for a follow-up visit after a fracture. The fracture is healing and the patient is still in a cast. How should the fracture be coded?

  1. As an acute fracture with the appropriate seventh character for routine healing Correct answer.
  2. As a sequela of the fracture
  3. As a nonunion of fracture
  4. As a personal history of fracture

Explanation

For follow-up visits for a healing fracture, the fracture code is assigned with the appropriate seventh character for the stage of healing (e.g., routine healing). The fracture is still being treated and is not a sequela or history.

Question 38Coding Guidelines and Regulatory Compliance

A hospital's coding audit reveals that a coder consistently assigned codes for a higher level of service than documented. Which action should the compliance officer take first?

  1. Report the coder to the OIG
  2. Terminate the coder immediately
  3. Ignore the findings as they are not significant
  4. Conduct a root cause analysis and provide education Correct answer.

Explanation

The first step in responding to a compliance issue is to investigate the cause and provide education and corrective action. Termination or reporting may be considered later depending on the severity and intent.

Question 39Coding Guidelines and Regulatory Compliance

Under the HIPAA Privacy Rule, a covered entity may use or disclose PHI for treatment, payment, and health care operations without patient authorization. Which of the following is considered a health care operation?

  1. Providing test results to a specialist for consultation
  2. Submitting a claim to an insurance company
  3. Discussing a patient's condition with a family member
  4. Conducting quality assessment and improvement activities Correct answer.

Explanation

Health care operations include quality assessment and improvement activities, competency assurance, and business planning. Treatment and payment are separate categories.

Question 40Coding Guidelines and Regulatory Compliance

A coder is assigning an ICD-10-CM diagnosis code based on a physician's operative report. The physician documents a condition as "probable" in the body of the report but lists a confirmed diagnosis in the final impression. According to the ICD-10-CM Official Guidelines for Coding and Reporting for inpatient facility coding, how should the coder assign the code?

  1. Defer coding until a pathology report confirms the diagnosis
  2. Code the condition as confirmed because it appears in the final impression Correct answer.
  3. Assign the code for the symptom rather than the probable condition
  4. Code the condition as uncertain and query the physician before assigning any code

Explanation

In inpatient facility coding, the ICD-10-CM Official Guidelines state that a diagnosis documented as probable, suspected, or likely at the time of discharge is coded as though it existed. When the final impression lists the condition as confirmed, that confirmed diagnosis governs code assignment.

Question 41Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

A physician performs a simple repair of a 2.5 cm superficial laceration of the forearm and a 1.5 cm simple repair of a superficial laceration of the cheek in the same session. Using integumentary repair coding, how are these repairs reported?

  1. Two codes, one per anatomic site grouping, each with its own length Correct answer.
  2. One code for the largest wound only; the smaller is bundled
  3. One code for the sum of all repairs as a single intermediate wound
  4. One code for the trunk and one for the face, regardless of depth

Explanation

Repair codes are selected by wound type (simple, intermediate, complex), by anatomic grouping (for example, face versus trunk/extremities), and by wound length. Wounds in different anatomic groupings are reported separately, and each grouping's total length drives code selection. Wounds in the same grouping are summed before selecting a code.

Question 42Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

Which layer is definitively reached when a lesion excision is documented as extending into the subcutaneous tissue?

  1. Epidermis only
  2. Dermis only
  3. Subcutaneous fat Correct answer.
  4. Deep fascia or muscle

Explanation

Excision codes are categorized by the deepest anatomic layer the excision reaches, and subcutaneous tissue is the fat layer beneath the dermis. Excision into the subcutaneous layer is coded as a subcutaneous lesion excision. Excisions reaching deep fascia or muscle are coded in a different category.

Question 43Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

A patient undergoes excision of a 0.8 cm benign lesion of the eyelid with a layered closure. Which coding approach is most appropriate?

  1. Excision of benign lesion by site and size, plus a layered repair code for the trunk
  2. Excision of benign lesion by site and size, plus an eyelid-specific repair code Correct answer.
  3. Excision of benign lesion with a complex repair code
  4. Excision of benign lesion with adjacent tissue rearrangement

Explanation

Eyelid lesion excisions are coded by site and size, and eyelid closures are reported using eyelid-specific repair codes rather than the general integumentary repair codes. General wound repair codes by length do not apply to the eyelids. The closure type and site determine which eyelid repair code is used.

Question 44Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

When a single lesion excision requires adjacent tissue transfer to close the defect, how is the procedure reported?

  1. The excision code plus the adjacent tissue transfer code, both reported
  2. The adjacent tissue transfer code plus a modifier indicating a staged procedure
  3. Only the excision code, with the transfer bundled
  4. Only the adjacent tissue transfer code, which includes the excision Correct answer.

Explanation

Adjacent tissue transfer or rearrangement codes include the primary excision of the lesion that created the defect. Reporting the excision separately would constitute unbundling. The transfer code is selected by the size of the defect and anatomic site.

Question 45Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

A 3.2 cm malignant lesion of the back is excised with margins and the defect is closed primarily. How is the excision reported?

  1. By the lesion diameter alone, without regard to margins
  2. By the length of the closure only
  3. By the total excised diameter including margins, using the malignant lesion codes Correct answer.
  4. By the defect size after closure

Explanation

For lesion excision, code selection is based on the largest diameter of the lesion plus the margins, and malignant lesions have their own code set. The excised diameter including margins determines the size range selected. Closure, if separately reportable, is coded by its own rules.

Question 46Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

Which statement correctly describes the coding of a biopsy versus an excision of a skin lesion?

  1. Biopsies are always coded with the malignant excision codes
  2. A biopsy removes the entire lesion and is coded as an excision
  3. A biopsy and an excision in the same session are always reported with only the excision code
  4. A biopsy removes a portion for diagnosis and is coded separately from a full excision Correct answer.

Explanation

A biopsy removes a sample of tissue for diagnostic evaluation, whereas an excision removes the entire lesion. Biopsy codes are distinct from excision codes. When both a biopsy and a full excision are performed, each may be reported when separately documented and medically necessary.

Question 47Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

A patient has a 4 cm simple repair on the arm and a 3 cm simple repair on the leg. How is the simple repair reported?

  1. Two codes with a modifier indicating separate sites
  2. A single intermediate repair code for 7 cm
  3. Two separate simple repair codes, one for each extremity
  4. A single simple repair code for the combined 7 cm length Correct answer.

Explanation

Wounds of the same type located in the same anatomic grouping (here, extremities) are summed for length before selecting the repair code. The combined length determines which simple repair code applies. Separate codes are not used within the same grouping.

Question 48Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

Which code family is used to report removal of a foreign body from the subcutaneous tissue of the hand?

  1. Adjacent tissue transfer codes
  2. Wound repair codes
  3. Excision of benign lesion codes
  4. Foreign body removal codes by anatomic site and depth Correct answer.

Explanation

Foreign body removal is reported with codes categorized by anatomic site and depth of the object (for example, subcutaneous versus muscle). These codes are distinct from lesion excision and repair codes. The depth and location documented in the operative note drive selection.

Question 49Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

A physician incises and drains a single subcutaneous abscess of the thigh. How is this reported?

  1. Adjacent tissue transfer code
  2. Incision and drainage code for the site, with no separate closure code Correct answer.
  3. Excision of benign lesion with complex closure
  4. Wound repair intermediate code only

Explanation

Incision and drainage of an abscess is reported with the appropriate incision and drainage code based on anatomic site and complexity. Routine closure of the drainage site is included and is not separately coded. Excision and repair codes do not describe drainage of an abscess.

Question 50Surgical Coding (Integumentary, Musculoskeletal, and Related Systems)

Which factor most directly determines the code selection for a complex wound repair?

  1. The number of sutures placed
  2. The total length of the wound and the anatomic grouping Correct answer.
  3. The patient's age and comorbidities
  4. The type of suture material used

Explanation

Complex repair codes are selected by wound length and anatomic grouping, similar to simple and intermediate repairs. The complexity of the repair (layered closure, extensive debridement, or scar revision) determines that a complex code applies at all. Suture count and material do not drive code selection.
