Unlisted and Not Otherwise Classified Procedure Codes
It is important, when billing any service, that providers always use the most appropriate CPT code that accurately describes the procedure performed.
The purpose of a NOC code is to report services having absolutely no existing code(s) that appropriately describe the service(s). Billers should use the reference aids available in the coding manuals before billing any service with a NOC code.
Upon medical review, services reported with NOC codes when specific codes are available will be denied; regardless of any supporting documentation accompanying the claim.
Medicare may view the deliberate use of inappropriate NOC codes for maximizing payments or "unbundling" procedures as a fraudulent billing practice. Misrepresentation of noncovered or non-chargeable services with NOC codes as approved, covered services is also inappropriate.

The following tips will help you bill NOC procedure codes
- Do not file unlisted or NOC codes for procedures (i.e., surgical) when there is an appropriate CPT code
