What type of coding is primarily focused on describing medical diagnoses?

The focus of coding that centers on describing medical diagnoses is primarily represented by ICD-10-CM (International Classification of Diseases, Tenth Revision, Clinical Modification). This coding system is specifically designed to capture a wide range of diseases, conditions, and health-related issues. ICD-10-CM codes are used to classify and describe the symptoms, complaints, and diagnoses encountered by healthcare providers in various clinical settings.

ICD-10-CM provides a standardized way to record and communicate the nature of a patient's condition, which is crucial for accurate documentation, billing, and epidemiological research. It allows healthcare providers and researchers to track geographic and temporal trends in diseases and facilitates the analysis of healthcare outcomes.

Other coding systems, such as ICD-10-PCS (which focuses on procedural coding), CPT (Current Procedural Terminology, used for outpatient procedures, services, and physician services), and HCPCS Level II (which includes codes for products, supplies, and non-physician services), serve different purposes and do not specifically address the documentation of medical diagnoses in the same comprehensive manner as ICD-10-CM does. Thus, it is the ICD-10-CM that is primarily focused on the description of medical diagnoses.
