AAPC CRC Course Notes

AAPC weight: 15/100. Think documentation support and lifecycle controls: prevent unsupported diagnoses before submission, detect/correct them after submission, understand CMS RADV medical-record validation, and never let risk-score impact override compliant coding.

• Submitting a clinically plausible but undocumented HCC diagnosis.

• Read the setting, documentation status, and current-year source before choosing a code or model answer.

AAPC weight: 30/100 and the largest domain. Master current-year ICD-10-CM rules, outpatient versus inpatient uncertainty, combination codes, hypertension/CKD/heart disease, diabetes manifestations, ulcers, malignancy/history, stroke sequelae, MI rules, respiratory conditions, status codes, and the common chronic conditions listed in the AAPC blueprint.

• Using lab thresholds to diagnose a condition the provider did not document.

• Read the setting, documentation status, and current-year source before choosing a code or model answer.

AAPC weight: 12/100. Identify ambiguous, conflicting, incomplete, or clinically inconsistent documentation; use compliant nonleading clarification; know which details may come from other clinicians; and keep provider diagnostic judgment separate from coder inference.

• Writing a query whose only meaningful option is the highest-paying diagnosis.

• Read the setting, documentation status, and current-year source before choosing a code or model answer.

AAPC weight: 5/100. Know the anatomy, common acronyms, and disease mechanisms behind high-frequency risk-adjustment conditions so you can understand documentation without diagnosing from clinical clues.

• Coding systolic HF solely from low EF.

• Read the setting, documentation status, and current-year source before choosing a code or model answer.

AAPC weight: 10/100. Know why risk adjustment exists, prospective timing, demographic factors, ICD-10-to-HCC mapping, trumping/hierarchies, interactions, new-enrollee logic, and the separation between valid coding and model output.

• Calling HCCs diagnosis codes.

• Read the setting, documentation status, and current-year source before choosing a code or model answer.

AAPC weight: 3/100. HEDIS and CMS Star Ratings are quality/performance systems, not HCC payment models. Accurate data can support both quality and risk adjustment, but one system never authorizes unsupported coding in the other.

• Treating HEDIS as a payment grouper.

• Read the setting, documentation status, and current-year source before choosing a code or model answer.

AAPC weight: 15/100. Identify the correct model by program and population: CMS-HCC for Medicare Advantage, HHS-HCC for ACA individual/small-group markets, CDPS in Medicaid contexts, ESRD segments where applicable, and payer-specific rules for private models.

• Using HHS-HCC coefficients for MA.

• Read the setting, documentation status, and current-year source before choosing a code or model answer.

AAPC ends with 10 integrated cases. The winning workflow is consistent: identify setting and source, determine what is actually documented, apply ICD-10-CM, distinguish current/history/status/complication, then apply model eligibility and mapping only after coding is correct.

• Coding 'rule out heart failure' as heart failure.

• Read the setting, documentation status, and current-year source before choosing a code or model answer.
