What Is an Add-on Code?
What exactly is an add-on code?Answer:
Add-on codes are part of the American Medical Association (AMA) Current Procedural Terminology (CPT) set of codes. They indicate work performed in addition to the primary service or procedure by the same physician. Parenthetical notes included in their descriptors may indicate reportable combinations.
Add-on codes are included in the AMA CPT Professional and Ophthalmic Coding Coach resources and can be identified by a plus sign symbol before the code and descriptors that include phrases such as “each additional” or “list separately in addition to the primary procedure.” They are not reportable as stand-alone codes.
Add-on codes are not subject to multiple procedure payment reductions and would be paid at the full allowable.
