What 24066 covers

A surgeon obtains tissue from a deep soft-tissue lesion in the upper arm or around the elbow for diagnostic evaluation. This is appropriate when the target lies beneath superficial tissues and sampling, rather than complete tumor removal, is the operative objective. Orthopedic surgeons, including orthopedic oncologists, commonly perform the procedure in a hospital or ambulatory surgery setting when the lesion requires operative access.

Report 24066 for a deep biopsy; distinguish it from the superficial biopsy in 24065. The operative report should identify the arm or elbow site, describe the target’s depth and the tissue sampled, and make clear that the service was a biopsy rather than excision. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures at 50%. For bilateral procedures reported with modifier 50, payment is 150%. Assistant-at-surgery payment is restricted; 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.

24066 billing questions

How do I choose between 24066 and 24065?

Use 24066 for a biopsy of deep soft tissue in the upper arm or elbow area. Use 24065 when the biopsied tissue is superficial.

When should the surgeon report an excision code instead?

Choose an excision code when the operative objective is removal of a lesion or tumor, rather than obtaining tissue for diagnosis. The relevant code depends on the tissue depth, size, and extent of removal.

Is the pathology examination included in 24066?

24066 describes the surgeon’s tissue acquisition. A pathology examination is a distinct service when separately performed and reported.

What documentation supports reporting 24066?

Document the upper-arm or elbow site, the target’s deep location, the tissue obtained, and the diagnostic biopsy intent. The operative note should distinguish sampling from removal of the lesion.

How does Medicare handle bilateral reporting and multiple procedures?

For a bilateral procedure reported with modifier 50, Medicare pays 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%.

Can an assistant, co-surgeon, or surgical team be reported?

Assistant-at-surgery payment is restricted for this code. Medicare does not permit co-surgeons or team surgery.

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.
