Callus

“My business partner and I have different opinions regarding this issue and I’m having trouble finding a succinct and primary source document. When performing nail care and callus care for a high-risk patient, can you bill for both when the callus is located on the tip of the toe? It is my understanding that the skin is a separate structure than the nail and thus they are separate diagnoses and CPT codes, but my business partner states he heard a lecture that stated not to charge for calluses that occur on the same toe as a nail that is trimmed or debrided. This seems to be an LCD-dependent decision as I have not been able to locate anything in CMS policy that states either way. Can someone point us in the right direction with primary source reference?”

For the “At Risk,” Routine Foot Care patient, can a mycotic toenail be debrided, and a corn/callus be trimmed on the same toe?
