Medical Billing (also known as RCM) uses an alphabet soup of acronyms. Let's start with defining the different types of codes that will be used to build and bill medical claims.
CPT - Current Procedural Terminology - codes used to report medical, surgical, and diagnostic procedures
HCPCS - Healthcare Common Procedure Coding System - codes used to report products, supplies, and services not included in the CPT code set
DSM5 - Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition - codes used by mental health professionals to classify mental disorders
ICD-10 - International Classification of Diseases, Tenth Edition - codes used to report a patient diagnosis
NDC - National Drug Code - a three-segment number used to identify finished, unfinished, and compounded drug products
