Coding and Reimbursement

The Current Procedure Terminology (CPT) code set is used to denote the medical and surgical procedures and diagnostic services rendered by providers. The CPT coding system provides a uniform language for describing these services for all billing and documentation and, under HIPAA, is required to be used for procedures provided by all providers and payers in the United States. The Centers for Medicare and Medicaid (CMS) assigns values to those CPT codes covered by Medicare and most insurance companies base their reimbursements on the values established by CMS for these procedure codes.

For the provider, the key to appropriate insurance reimbursement lies in accurate procedure coding. Coding errors can lead to delayed payments or rejections of submitted claims. Consistent errors can trigger audits, or even charges of fraud and abuse, and removal from managed care networks. Always verify CPT information with the AMA's current CPT manual, which is the ultimate authority on procedure coding.
