PCA CPP key terms

The determination that a service is reasonable, necessary, and appropriate for diagnosing or treating a patient's condition, supported by documentation in the record. Payers deny claims lacking this support.

A CMS form a provider gives a Medicare patient before a service likely to be denied as not medically necessary, shifting financial liability to the patient if signed. Correct use protects the practice from write-offs.

A HCPCS Level II modifier appended to a claim line indicating an ABN is on file for that item or service expected to be denied as not reasonable and necessary. It signals waiver of liability.

A HCPCS Level II modifier showing the provider expects a service to be denied as not medically necessary but no ABN was obtained. Liability generally stays with the provider.

The rules specifying which history, examination, and medical decision-making elements must be recorded to support an evaluation and management code level. Current CMS guidance uses medical decision making or time.

The E/M component scoring complexity through number and complexity of problems addressed, amount of data reviewed, and risk of complications, morbidity, or mortality. It sets the visit level under current rules.

The cumulative minutes on the date of the encounter spent in face-to-face and non-face-to-face activities personally performed by the billing practitioner, such as reviewing records, ordering tests, and documenting. It can select an E/M level.

Add-on codes reported when a practitioner's time on a date exceeds the threshold of the highest-level service in that category, such as 99417 for outpatient E/M. Thresholds and units differ by code family.

Services furnished by auxiliary personnel under a physician's direct supervision and integral to the physician's plan of care, billed under the physician's number. Rules differ between Medicare and private payers.

An E/M encounter in a facility setting jointly performed by a physician and a non-physician practitioner in the same group. The billing practitioner is chosen by who performed the substantive portion.

The bundle of services included with a surgical procedure: the operation, typical postoperative care, and minor related visits. Its length (0, 10, or 90 days) depends on the procedure's global indicator.

The number of days after a procedure during which routine follow-up care is included in the surgical payment and not separately billable. It begins the day before surgery for major procedures.

Appended to an E/M service during a postoperative global period when the visit is unrelated to the original procedure. The record must show the reason is distinct from the surgical diagnosis.

Reported on an E/M service that led to the initial decision to perform major surgery, allowing separate payment despite the upcoming global period. It is not used for minor procedures.

Appended to a significant, separately identifiable E/M service on the same day as another procedure or service by the same practitioner. Documentation must support that the E/M went beyond routine pre- or post-procedure work.

Indicates a procedure or service was distinct and independent from other services reported on the same day, overriding a bundling edit. Specific X modifiers are preferred when they accurately describe the circumstance.

A family of four modifiers (XE, XP, XS, XU) that more precisely explains why a service is separate: separate encounter, practitioner, site, or unusual non-overlapping service. They replace modifier 59 in many cases.

Payer rules, such as the National Correct Coding Initiative, that pair codes considered components of one another and deny separate payment unless an appropriate modifier and documentation justify it.

A two-digit code on the claim identifying where the service was furnished, such as office, hospital outpatient, or ambulatory surgical center. It affects payment rates and which code set applies.

A payment distinction for professional services based on whether the practitioner's practice bears the cost of the office overhead. Facility rates are lower because the institution supplies resources and staff.

A four-digit code on institutional claims describing the type of charge, such as room and board, pharmacy, or operating room. It appears with the bill type and is not used on professional claims.

The standard paper form for professional claims, carrying patient, insured, diagnosis, and service line data. Its electronic counterpart is the 837P transaction under HIPAA.

A statement from the payer showing charges submitted, allowed amount, payment, adjustments, and patient responsibility. Reading it correctly is essential for posting payments and appealing denials.

The maximum a payer will recognize for a covered service under its fee schedule or contract. Payment plus patient responsibility equals this figure; charges above it are usually written off.

A payer's list of payment amounts by code, often derived from relative value units multiplied by a conversion factor and adjusted geographically. It determines the allowed amount for contracted services.

A weighted unit reflecting physician work, practice expense, and malpractice cost for a service. Medicare multiplies total RVUs by a conversion factor and geographic adjustment to set payment.

The dollar multiplier applied to total relative value units to produce a Medicare payment amount. It is updated annually and differs for qualified and non-qualified practitioners.

The percentage of the allowed amount a beneficiary owes after the deductible is met, commonly 20 percent under Medicare Part B. It is separate from copayments and from the deductible itself.

A claim submitted without errors or missing information that a payer can process without manual intervention. Timely filing and complete data elements are required for this status.

A payer's refusal to pay a claim, often for eligibility, coding, medical necessity, or timely filing reasons. Denials are tracked and worked through appeals or corrected claims.

A formal request that a payer reconsider a denied or underpaid claim, typically with supporting records and a rationale. Levels and deadlines are set by the payer and by regulation for Medicare.

An ICD-10-CM instruction stating two codes cannot be reported together because the conditions are mutually exclusive. It differs from an Excludes2 note, which permits reporting both codes.

An ICD-10-CM note meaning the excluded condition is not part of the coded condition but may be reported separately when both are present and documented. It does not prohibit dual coding.

The condition established after study to be chiefly responsible for the inpatient admission. Sequencing rules require it to be listed first on inpatient claims.

The diagnosis reported first on an outpatient claim, describing the condition chiefly responsible for the services provided. It corresponds to the principal diagnosis concept in the outpatient setting.

A flag on inpatient claims showing whether a diagnosis was present when the patient was admitted. It supports quality reporting and payment adjustments for hospital-acquired conditions.

A five-character alphanumeric code beginning with a letter, used for supplies, drugs, durable medical equipment, and services not represented in CPT. It is maintained by CMS and updated quarterly.

A unique identifier for a drug product assigned by the manufacturer, reported with units and qualifiers on drug claims. Payers use it to verify the correct HCPCS code and dosage billed.

A HCPCS Level II code describing a specific injectable drug and its dosage unit, such as per 10 mg. Billing requires reporting the units administered based on the amount discarded and given.

A five-digit code from the Current Procedural Terminology system describing medical services and procedures. Category I codes are numeric; Category III codes are temporary and alphanumeric with a trailing T.

The inpatient procedure classification system using seven-character alphanumeric codes built from axes such as root operation, body system, and device. It is used on inpatient hospital claims, not professional claims.

The third character of an ICD-10-PCS code defining the objective of the procedure, such as excision, resection, or drainage. Choosing the correct root operation is central to accurate inpatient coding.

A laboratory test classified as simple and low risk, exempt from most CLIA requirements. Waived tests carry specific CPT codes and are often performed in physician offices.

The split of certain diagnostic services into the facility's resource cost (technical) and the practitioner's interpretation (professional). Modifier 26 bills the professional part; TC bills the technical part.

Appended to a radiology or diagnostic code when only the professional interpretation is billed, such as by a radiologist reading a hospital image. The facility bills the technical component separately.

Appended to a diagnostic service code when billing only the technical component, covering equipment, supplies, and technologist time. It is common for independent imaging centers and hospital outpatient billing.

A modifier such as RT, LT, or a digit indicating the specific body side or digit on which a procedure was performed. It supports medical necessity and reduces duplicate-claim denials.
