What Are CPT Codes?

CPT (Current Procedural Terminology) codes are 5-digit numeric codes used to describe:

• Medical services

• Diagnostic tests

• Surgical procedures

• Telehealth and preventive care

They are maintained by the American Medical Association (AMA) and used by all payersincluding Medicare, Medicaid, and private insurance companies.

Can You Access CPT Codes for Free?

Technically, CPT codes are copyrighted by the AMA, so full access to their detailed descriptions and official usage guidelines typically requires a paid license. However, there are several reliable free CPT code search options that provide:

• Partial code descriptions

• Code categories

• Code status (active or deleted)

• Associated ICD-10 or HCPCS info (in some cases)

Lets explore the top free tools available.
