- Hierarchical Condition Category (HCC)
- Related: Risk Adjustment Factor (RAF) score, MEAT criteria
A diagnosis grouping used in risk-adjustment payment models; each enrollee's documented conditions map to categories that predict future cost and set capitation payment.
- Risk Adjustment Factor (RAF) score
- Related: Hierarchical Condition Category (HCC), Suspected condition
A numeric value summarizing the predicted cost of caring for a patient, calculated from documented HCCs, demographics, and model version; it drives payment in Medicare Advantage and similar plans.
- MEAT criteria
- Related: TAMPER criteria, Problem list reconciliation
A documentation test for whether a condition can be reported: the record must show Monitoring, Evaluation, Assessment, or Treatment of that condition during the encounter, not merely a past-history mention.
- TAMPER criteria
- Related: MEAT criteria, Problem list reconciliation
An alternative documentation standard requiring Treatment, Assessment, Monitor, Plan, Evaluate, or Referral evidence before a chronic condition is coded; often applied to risk-adjustment audits in place of MEAT.
- Problem list reconciliation
- Related: MEAT criteria, Suspected condition
The CDI and provider process of reviewing the cumulative problem list against visit notes to resolve stale, duplicated, resolved, or conflicting diagnoses before coding and billing.
- Suspected condition
- Related: Unspecified code, Query
A diagnosis a provider is considering but has not confirmed; outpatient coding rules generally prohibit reporting it as confirmed, so CDI prompts clarification of status and workup.
- Unspecified code
- Related: Specificity, Query
An ICD-10-CM code used when the record lacks detail to assign a more specific code; frequent use signals documentation gaps that outpatient CDI should address through clarification.
- Specificity
- Related: Unspecified code, Query
The level of clinical detail in a diagnosis code, such as laterality, severity, or type; higher specificity improves payment accuracy, quality reporting, and risk-adjustment capture.
- Query
- Related: Clinical indicator, Provider engagement
A written or verbal request from CDI or coding staff asking a provider to clarify or add documentation, ideally non-leading and supported by clinical indicators in the record.
- Clinical indicator
- Related: Query, Provider engagement
Objective evidence in the record, such as lab values, imaging results, or vital signs, that supports a diagnosis and justifies a query when documentation is ambiguous or incomplete.
- Provider engagement
- Related: Query, CDI education
The work of building trust and collaboration with physicians so they accept CDI feedback, respond to queries, and adopt documentation habits that reflect the care they deliver.
- CDI education
- Related: Provider engagement, Documentation template
Targeted teaching for clinicians and staff on documentation standards, coding impacts, and query response, usually delivered through brief sessions, specialty-specific examples, and feedback reports.
- Documentation template
- Related: Copy-forward documentation, CDI education
A structured note format that prompts clinicians for required clinical elements, reducing omissions and supporting accurate code assignment without encouraging cloned or copy-pasted content.
- Copy-forward documentation
- Related: Documentation template, Problem list reconciliation
Reusing prior note text in a new encounter; it creates risk of outdated or unsupported diagnoses and is a common audit finding that outpatient CDI must detect and correct.
- Medical decision making (MDM)
- Related: Evaluation and Management (E/M) level, Time-based coding
The complexity of establishing diagnoses, assessing data, and selecting management options; it is a component of outpatient E/M level selection and a focus of CDI review.
- Evaluation and Management (E/M) level
- Related: Medical decision making (MDM), Time-based coding
The service intensity category assigned to an outpatient visit, determined under current rules by either medical decision making or total time on the date of the encounter.
- Time-based coding
- Related: Evaluation and Management (E/M) level, Medical decision making (MDM)
Selecting an E/M level using the total minutes spent on the encounter date on practitioner activities, including documentation and care coordination, rather than MDM elements.
- Hospital outpatient clinic
- Related: Place of service, Facility versus professional coding
A clinic owned or operated by a hospital and billed under the outpatient prospective payment system; CDI there must align facility and professional documentation and code sets.
- Place of service
- Related: Hospital outpatient clinic, Facility versus professional coding
A two-digit code on a claim identifying where the service occurred, such as office or hospital outpatient; it affects payment and which coding rules apply.
- Facility versus professional coding
- Related: Hospital outpatient clinic, Place of service
The split between the hospital's facility code assignment for resources used and the physician's professional code assignment for the service; CDI must support both consistently.
- Chief complaint
- Related: History of present illness (HPI), Emergency department CDI
The patient's stated reason for the visit, recorded in the patient's own words; it anchors the emergency department note and guides history and diagnostic workup.
- History of present illness (HPI)
- Related: Chief complaint, Review of systems (ROS)
The chronologic description of the patient's current problem, including onset, location, duration, severity, and modifying factors; its completeness supports diagnosis and level of service.
- Review of systems (ROS)
- Related: History of present illness (HPI), Past medical, family, and social history (PMFSH)
A systematic inventory of body-system symptoms reported by the patient or caregiver; in the emergency department it is often abbreviated and must be documented rather than assumed.
- Past medical, family, and social history (PMFSH)
- Related: Review of systems (ROS), Problem list reconciliation
The record of prior conditions, family illnesses, and social factors such as tobacco or housing; it supports risk capture and identifies conditions needing monitoring or treatment.
- Emergency department CDI
- Related: Chief complaint, Observation status
Concurrent review of ED documentation to ensure presenting problems, workups, and final diagnoses are clearly stated, since brief encounters and shift changes frequently leave gaps.
- Observation status
- Related: Emergency department CDI, Two-midnight rule
A hospital outpatient status for patients needing short-term monitoring and reassessment; it carries different billing rules and requires documentation that supports the decision.
- Two-midnight rule
- Related: Observation status, Admission order
A Medicare inpatient admission standard based on the expectation that the patient will need hospital care spanning at least two midnights; documentation of that expectation is essential.
- Admission order
- Related: Two-midnight rule, Observation status
The physician's documented order to admit a patient as inpatient; it must be present and timely because it determines billing status independent of later documentation.
- Telehealth CDI
- Related: Remote patient monitoring, Documentation template
Review of documentation from video or audio visits, where limited physical exam and remote workflows create specific risks of unsupported diagnoses and incomplete assessment.
- Remote patient monitoring
- Related: Telehealth CDI, Care management services
Collection and transmission of patient physiologic data from home devices for clinical review; documentation must show the data were interpreted and used in management.
- Care management services
- Related: Remote patient monitoring, Annual wellness visit
Bundled non-face-to-face services such as chronic care management that require documented care plans, time tracking, and patient consent to be billable.
- Annual wellness visit
- Related: MEAT criteria, Care management services
A preventive visit focused on a personalized prevention plan; it is not a problem-oriented exam, so chronic conditions must still be documented with MEAT to be reported.
- Surgical center CDI
- Related: Procedure documentation, Anesthesia documentation
Review of ambulatory surgery documentation to confirm preoperative diagnoses, procedure details, and postoperative findings are stated clearly enough to support coding and payment.
- Procedure documentation
- Related: Surgical center CDI, Anesthesia documentation
The operative or procedural note describing technique, findings, specimens, and complications; missing elements force unspecified codes or lost reimbursement.
- Anesthesia documentation
- Related: Surgical center CDI, Procedure documentation
The record of anesthetic type, agents, monitoring, and patient response; it supports anesthesia coding and physical status assignment in outpatient surgical settings.
- Behavioral health integration
- Related: Care management services, Social determinants of health
Embedding mental health screening and treatment into primary care; documentation must capture screening results, diagnoses, and collaborative care to support coding and quality measures.
- Social determinants of health
- Related: Behavioral health integration, Annual wellness visit
Non-medical factors such as food insecurity, housing, and transportation that affect outcomes; standardized codes exist for them and capture requires clear documentation.
