What is medical insurance coding?

Medical insurance coding is the process of translating healthcare diagnoses, procedures, medical services, and equipment into standardized codes. These codes are used on medical records and billing documents to ensure that healthcare providers are properly reimbursed by insurance companies. Coders use classification systems such as ICD-10, CPT, and HCPCS to assign codes based on physician documentation and patient records. Accurate coding is essential for healthcare providers to receive timely payments and to avoid claim denials or audits.
