Op Report: A curvilinear incision was made over dorsum of the left ring finger DIP joint. Dissection was carried through subcutaneous tissue. Full-thickness skin & subcutaneous tissue flaps were elevated. The mucous cyst was localized pretty centrally over the extensor mechanism distal to the DIP joint. The cyst was identified & mobilized & excised and originated from the dorsal ulnar corner of the joint. Both the dorsal Ulnar & dorsal Radial corner of the joint were identified & osteophytes were debrided with a rongeur off the base of the distal phalanx. The penrose drain was removed & bleeding controlled with electrocautery. The incision was irrigated & closed.

Coded with 26210 & 26160. One of our coders says per Margie Vaught that this is how we should be billing these. I feel that 26160 would include the debridement of the osteophytes since all through same incision. Can anyone advise on this issue. I found several questions similar to this, but am confused on why would these billed together when done through same incision. CPT Code 26210 is a Column 1 code with 26160 being a column 2 code, but unbundling is allowed. Thanks in advance for anyone who may be able to help.
