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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

20205 billing questions

How is this distinguished from a superficial muscle biopsy?

Use 20205 when the open approach reaches deep muscle tissue. A superficial muscle sample is reported with 20200.

How does this differ from a percutaneous muscle biopsy?

This code describes an open approach to deep muscle. Use 20206 when the muscle is sampled percutaneously with a needle.

Is the pathology examination included?

The code reports obtaining the muscle specimen. A pathologist may separately report the tissue examination, such as 88305, when that service is performed and documented.

Can modifier 50 be used for biopsies on both sides?

Modifier 50 is inappropriate for this descriptor and anatomy, so do not report a bilateral adjustment.

Can an assistant surgeon or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 20205. Co-surgeon and team-surgery reporting are not permitted.

What same-session payment reduction should the billing team expect?

When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure payment.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
