Current Procedural Terminology (CPT) codes are standardized five-digit codes developed by the American Medical Association (AMA) to describe medical, surgical, diagnostic, and evaluation services. Healthcare providers use CPT codes to document patient care, submit insurance claims, and receive reimbursement from Medicare, Medicaid, and commercial insurance companies.
Accurate CPT coding is essential for successful medical billing, reducing claim denials, and ensuring providers are paid correctly. Below are five of the most commonly used CPT codes across many healthcare specialties.
