33223 Defibrillator pocket Medicare reimbursement rates in Maine

The implanting physician opens the existing pocket, frees the defibrillator generator, creates a pocket in a different location, and places the generator there. This may be done when the current pocket causes discomfort or has inadequate tissue coverage. The procedure is typically performed by a cardiac electrophysiologist or other implanting specialist in a hospital or surgical facility; the generator is moved while the existing system’s leads generally remain in place.

Report 33223 when the operative work relocates the defibrillator pocket, rather than merely repositioning a lead or replacing the generator. Document the reason for relocation, the original and new pocket sites, and the work performed on the generator and leads. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is not appropriate. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
