Assigning numeric and alphanumeric codes to diagnoses, procedures and services.

Coding and abstracting uses classification systems such as ICD-10-CM for diagnoses and CPT or HCPCS for procedures to translate clinical documentation into standardized codes. These codes are essential for billing, reimbursement, statistical reporting, and healthcare data analysis across the industry.

Incomplete record processing is the administrative function focused on identifying, tracking, and resolving deficiencies in patient medical records, not assigning codes.

Record circulation refers to the tracking and management of the physical or electronic movement of health records within or between facilities, not the coding process.
