Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 20205 covers

The clinician obtains a muscle specimen through an incision that reaches deep muscle tissue. This approach may be selected when evaluation of suspected neuromuscular disease requires tissue for laboratory examination and a needle sample is not performed. A surgeon commonly performs the procedure in a hospital or ambulatory surgery setting; the specimen is sent for pathologic evaluation.

Select this code for an open biopsy of deep muscle, not a superficial muscle sample or percutaneous needle biopsy. The operative note should identify the muscle sampled and document the open approach and depth. Same-day preoperative and postoperative care is included in the 0-day global period. When other procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate for this descriptor and anatomy. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
