What is physician coding?

Physician coding is the process of translating medical diagnoses, procedures, services, and equipment used during patient care into standardized codes. These codes are used for billing, insurance claims, and maintaining accurate medical records. Physician coders use classification systems such as ICD-10-CM, CPT, and HCPCS to ensure healthcare providers are properly reimbursed and compliant with regulations. Accuracy in coding is crucial to prevent claim denials and support quality patient care.
