Question: Kansas Subscriber Answer: • 29822 -- Arthroscopy, shoulder, surgical; debridement, limited • 29823 -- ... debridement, extensive. The debridement often requires an acromioplasty, which is code 29826 (Arthroscopy, shoulder, surgical; decompression of subacromial space with partial acromioplasty, with or without coracoacromial release). Keep these tips in mind, however, before adding 29826 to your claim: • Do not report 29826 if your surgeon's notes don't mention acromioplasty. • You cannot report 29826 with 29822. • You sometimes can report 29826 with 29823, depending on the circumstances. Example: If the physician completes both the acrominoplasty and debridement within the subacromial bursa, you'll report only 29823. If he completes acrominoplasty within the subacromial bursa and the debridement within another area (such as in the gleno-humeral [GH] joint), you can submit both codes.
