CRC · Get comfortable with the vocabulary.

Hierarchical Condition Category (HCC)

A grouping of ICD-10-CM diagnosis codes that maps to a single risk weight used in risk adjustment models; each enrollee's HCCs combine to produce a risk score.

Related: Risk Adjustment Factor (RAF) score, RxHCC, Model Output
Risk Adjustment Factor (RAF) score

A numeric value summarizing expected healthcare costs for an individual relative to the average beneficiary, calculated from demographic factors and documented HCCs in a given payment year.

Related: HCC, Hierarchical Condition Category (HCC), Model Output
RxHCC

A risk adjustment model used for Medicare Part D prescription drug coverage, grouping diagnoses and age/sex factors to predict drug costs separately from the medical HCC model.

Related: HCC, Risk Adjustment Factor (RAF) score, Payment Year
Model Output

The final risk score produced by a risk adjustment model after applying hierarchies, interactions, and demographic factors to the diagnoses submitted for an enrollee.

Related: HCC, Risk Adjustment Factor (RAF) score, Hierarchy
Payment Year

The calendar year in which a risk adjustment payment applies; diagnoses from a prior data collection year are used to calculate the score for this year.

Related: Risk Adjustment Factor (RAF) score, Model Output, Data Collection Year
Data Collection Year

The year in which diagnoses are captured from claims or encounters to calculate risk scores for a subsequent payment year, often with a specified submission deadline.

Related: Payment Year, Encounter Data, Risk Adjustment Processing System (RAPS)
Hierarchy

A rule within an HCC model that groups related conditions so that only the most severe or resource-intensive condition in a category contributes to the risk score.

Related: HCC, Model Output, Comorbidity
Comorbidity

A medical condition that coexists with the primary condition being treated; in risk adjustment, documented comorbidities can increase the RAF score when they map to distinct HCCs.

Related: Hierarchy, HCC, Sequencing
ICD-10-CM

The clinical modification of the International Classification of Diseases, Tenth Revision, used in the United States to code diagnoses and support risk adjustment, quality reporting, and billing.

Related: Specificity, Laterality, Excludes1 Note
Specificity

The level of detail in a diagnosis code that fully describes the condition's type, site, severity, and cause; higher specificity improves risk adjustment accuracy and compliance.

Related: ICD-10-CM, Documentation Gap, Query
Laterality

The designation of right, left, or bilateral for paired organs or body sites; many ICD-10-CM codes require laterality to be complete and accurately reflect the condition.

Related: Specificity, ICD-10-CM, Documentation Gap
Excludes1 Note

An ICD-10-CM instruction indicating that two codes cannot be reported together because the conditions are mutually exclusive; one must be selected based on documentation.

Related: Excludes2 Note, ICD-10-CM, Sequencing
Excludes2 Note

An ICD-10-CM instruction indicating that a condition is not included in the code's definition but may be reported separately when both conditions are present and documented.

Related: Excludes1 Note, ICD-10-CM, Comorbidity
Documentation Gap

Missing or insufficient clinical information in the medical record that prevents accurate code assignment, often requiring a provider query to clarify specificity, linkage, or clinical significance.

Related: Query, Specificity, Chart Review
Query

A formal communication to a provider requesting clarification or additional documentation to support accurate diagnosis coding, without leading the provider to a specific answer.

Related: Documentation Gap, Specificity, Compliance Audit
Medical Record Documentation

The clinical notes, test results, and other entries in a patient's chart that must support every diagnosis code reported for risk adjustment and billing purposes.

Related: Documentation Gap, Chart Review, Compliance Audit
Sequencing

The order in which diagnosis codes are reported, typically placing the principal or first-listed diagnosis first, followed by secondary diagnoses that are relevant to the encounter.

Related: Principal Diagnosis, Comorbidity, Excludes1 Note
Principal Diagnosis

The condition established after study to be chiefly responsible for the patient's admission or encounter, and the first diagnosis reported in the sequence.

Related: Sequencing, Comorbidity, Linkage
Linkage

The documentation that connects a manifestation or complication to an underlying disease, such as diabetic retinopathy linked to diabetes, required for correct combined code assignment.

Related: Sequencing, Diabetes with Complications, Comorbidity
Diabetes with Complications

A coding category requiring documentation that a specific complication (e.g., neuropathy, nephropathy, retinopathy) is due to diabetes, often needing a combination code and linkage statement.

Related: Linkage, Chronic Kidney Disease (CKD), Sequencing
Chronic Kidney Disease (CKD)

A long-term condition of reduced kidney function staged by glomerular filtration rate; risk adjustment coding requires documenting the stage and any linkage to diabetes or hypertension.

Related: Diabetes with Complications, Linkage, HCC
COPD

Chronic obstructive pulmonary disease, a progressive lung condition often coded with specificity for exacerbation, obstruction type, and associated conditions such as asthma or tobacco use.

Related: Specificity, Comorbidity, HCC
Cancer Diagnosis Coding

The assignment of ICD-10-CM codes for malignant neoplasms, requiring documentation of the primary site, histology, behavior, and any metastasis or treatment focus.

Related: Metastasis, Specificity, HCC
Metastasis

The spread of cancer from a primary site to a secondary site; coding requires distinguishing primary from secondary sites and documenting whether the encounter is for treatment of the primary or metastatic disease.

Related: Cancer Diagnosis Coding, Specificity, Sequencing
Cardiovascular Disease Coding

The coding of heart and blood vessel conditions such as heart failure, myocardial infarction, and hypertension, often requiring specificity for type, acuity, and causal relationships.

Related: Specificity, Linkage, HCC
Risk Adjustment Processing System (RAPS)

A legacy CMS system used by Medicare Advantage organizations to submit diagnosis data for risk score calculation, later supplemented by encounter data.

Related: Encounter Data, Data Collection Year, Risk Adjustment Factor (RAF) score
Encounter Data

Claims-like records submitted by providers or health plans that capture diagnoses and services; CMS uses encounter data to calculate risk scores for Medicare Advantage enrollees.

Related: Risk Adjustment Processing System (RAPS), Data Collection Year, HCC
Chart Review

A retrospective audit of medical records to verify that reported diagnosis codes are supported by documentation, often used to identify missed HCCs or coding errors.

Related: Documentation Gap, Compliance Audit, HCC
Compliance Audit

A systematic examination of coding and documentation practices against CMS and other regulatory standards to ensure accuracy, detect fraud, and identify improvement areas.

Related: Chart Review, Documentation Gap, Query
Risk Score Capture

The process of identifying and submitting all documented, clinically valid diagnoses that map to HCCs so that the calculated risk score reflects the enrollee's expected cost.

Related: HCC, Chart Review, Documentation Gap
Quality Reporting

The submission of clinical performance measures (e.g., HEDIS, Star Ratings) that may be affected by diagnosis coding accuracy and documentation completeness.

Related: Value-Based Initiatives, Compliance Audit, HCC
Value-Based Initiatives

Payment and care delivery models that reward providers for quality and cost efficiency, often relying on accurate risk adjustment to compare performance across patient populations.

Related: Quality Reporting, Risk Adjustment Factor (RAF) score, Compliance Audit
Medicare Advantage

A Medicare program option in which private plans provide benefits; these plans are paid using risk-adjusted capitation based on enrollee HCCs and demographic factors.

Related: HCC, Risk Adjustment Factor (RAF) score, Encounter Data
ACA Risk Adjustment

A permanent program under the Affordable Care Act that transfers funds among individual and small group market insurers to offset the cost of high-risk enrollees, using a separate HCC model.

Related: HCC, Risk Adjustment Factor (RAF) score, Model Output
Suspect HCC

An HCC identified during chart review as potentially present but not documented or coded, requiring validation before inclusion in risk score calculations.

Related: Chart Review, Documentation Gap, Risk Score Capture
HCC Recapture

The annual process of documenting and reporting chronic conditions that persist year after year so that they continue to contribute to the enrollee's risk score in the current payment year.

Related: Payment Year, Data Collection Year, HCC
MEAT Criteria

A documentation standard requiring that a condition be Monitored, Evaluated, Assessed, or Treated in the record to support code assignment for risk adjustment.
