When a code does not exist that accurately describes the procedure/treatment, the coder should report

Answer;

-Unlisted code

Explanation;

-When a code does not exist that accurately describes the procedure or treatment, the coder should report an unlisted code.

-Unlike other CPT codes, unlisted codes do not describe a  specific procedure or service. Relative value units are not assigned to unlisted  codes because the codes do not identify usual procedural  components or the effort/skill required for the service.

-Therefore; When using an unlisted code it is necessary to provide  specific information regarding the procedure(s) identified  by the code.
