Unlisted CPT, Unclassified HCPCS and NDC Codes

Please include an explanation of the service performed when submitting claims for an unlisted CPT code or an unclassified HCPCS code. Submit all unlisted and unclassified codes with a quantity of '1'. All unlisted and unclassified codes are subject to review.

Please submit unlisted CPT codes (i.e. 33999) with an explanation of the specific procedure performed. Submit unclassified drug codes (i.e. J8499) with the NDC and narrative description of the corresponding pharmaceutical submitted.

If you submit a paper claim, please note the descriptive information in field 19 of the CMS-1500 form, or field 80 of the UB-04 form. If you file a claim electronically, please use the ‘remarks’ field for the description and NDC.

We will return any claim containing an unclassified drug code without a description and NDC for additional information.
