COC (Formerly CPC-H) study plan

Apply ICD-10-CM conventions (Excludes1/Excludes2, Includes, Code also, NEC/NOS, sequencing, etiology/manifestation) to 30 coding scenarios

Code 40 diagnoses across high-yield chapters: diabetes, neoplasms, circulatory, respiratory, digestive, musculoskeletal, and injuries with 7th-character requirements

Assign CPT codes from the Surgery and E/M sections to 30 synthetic encounters, applying the correct level of service and site-of-service rules

Select and sequence modifiers (25, 57, 59, 76, 78, 79, 91, LT/RT, 50) on 20 claim scenarios and justify each

Code radiology, pathology/laboratory, and medicine sections including drug administration and vaccine coding

Map 20 outpatient services to the correct revenue codes and verify the UB-04 bill type and service-line construction

Explain APC assignment logic, status indicators, packaging, and discounting rules and apply them to 15 claim scenarios

Diagnose the top denial categories (medical necessity, coding, eligibility, timely filing, bundling) and draft a prevention action for each

Sequence the charge capture-to-claim flow and identify three control points where documentation errors become denials
