How are unlisted procedure codes presented in the CPT?

Answer 1

Unlisted procedure codes in the Current Procedural Terminology (CPT) are designated with a specific code that typically ends in "99," indicating that the procedure is not described by existing codes. These codes are used when a service or procedure is performed that does not have a specific CPT code assigned to it. Practitioners must provide detailed reports to justify the use of unlisted codes, explaining the nature of the procedure, the reason for its necessity, and any relevant details to ensure proper reimbursement. Unlisted codes allow for flexibility in billing while maintaining a standardized coding system.
