Question: Should I use 29846 (Arthroscopy, wrist, surgical; excision and/or repair of triangular fibrocarti-lage and/or joint debridement) for the arthroscopic excision of a ganglion, dorsal left wrist? We couldn't find a specific code in CPT that addresses this type of surgery. New Jersey Subscriber
Answer: No, 29846 is not appropriate for this type of procedure. You should use 29999 (Unlisted procedure, arthroscopy) instead.
Many practices are hesitant to report the unlisted-procedure code because it often slows claim processing, but in your situation, this is your best bet. It isn't correct coding to choose a code "close" to the procedure performed. If no accurate code exists, always go with the unlisted-procedure code.
