Medical coding is a crucial aspect of the healthcare industry, involving the transformation of medical diagnoses, procedures, treatments, and services into standardized alphanumeric codes. These codes are used for billing, insurance claims, and maintaining patient records.
Medical coding translates healthcare services into universal medical codes based on classification systems such as:

ICD (International Classification of Diseases)
CPT (Current Procedural Terminology)
HCPCS (Healthcare Common Procedure Coding System)
