What 20200 covers

A physician obtains a small sample of accessible skeletal muscle through an open incision for diagnostic examination. Neurologists and surgeons may perform this procedure when evaluation of conditions such as inflammatory myopathy, muscular dystrophy, or metabolic muscle disease requires tissue. The specimen may be sent for histologic or other laboratory studies. This code describes a superficial muscle biopsy, not a needle sample or an open biopsy of a deeper muscle.

Select the code based on the muscle’s depth and the approach documented in the operative report. Documentation should identify the sampled muscle and site, the open approach, and the diagnostic reason for obtaining tissue. The 0-day global period includes same-day preoperative and postoperative care. If 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 inappropriate. Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.

20200 billing questions

How does this differ from 20205?

Use 20200 for an open biopsy of superficial muscle. Code 20205 describes an open biopsy of deep muscle.

When is 20206 more appropriate?

Code 20206 describes a percutaneous needle muscle biopsy. Use 20200 when the documented method is an open biopsy of superficial muscle.

Can modifier 50 be used for biopsies on both sides?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.

Is same-day postoperative care separately included?

The code has a 0-day global period, which includes same-day preoperative and postoperative care.

Can an assistant or co-surgeon report this procedure?

Medicare does not pay an assistant-at-surgery claim for 20200. Co-surgeons and team surgery are not permitted.

What documentation supports reporting 20200?

The operative report should identify the muscle and site, establish that the biopsy was open and superficial, and state why tissue was obtained.

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.
