What 20225 covers

The clinician advances a biopsy needle or trocar through the skin to obtain tissue from a deep bone site. Orthopedic surgeons, radiologists, and interventional radiologists may perform the procedure when evaluation of a bone lesion, suspected osteomyelitis, or another bone abnormality requires tissue. The procedure is distinct from an open biopsy, which uses a surgical exposure, and from needle sampling of a superficial bone site.

Report 20225 when the documented approach is percutaneous and the sampled bone is deep; the operative or procedure note should identify the bone and target, the needle or trocar technique, and the reason for sampling. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur 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 for this code. Medicare does not pay an assistant at surgery, and 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.

20225 billing questions

How does 20225 differ from 20220?

Both describe percutaneous bone sampling with a needle or trocar. Choose 20225 for a deep bone site and 20220 for a superficial bone site.

When is 20245 more appropriate?

20245 describes an open biopsy of a deep bone. Use 20225 when the deep-bone sample is obtained percutaneously with a needle or trocar.

Can modifier 50 be used for bilateral bone biopsies?

No. CMS identifies modifier 50 as inappropriate for 20225; document the sampled site or sites and follow applicable coding instructions.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 20225. Co-surgeons and team surgery are not permitted.

What same-day care is included in the payment?

The 0-day global period includes same-day preoperative and postoperative care. Routine care related to the biopsy is part of the procedure.

How are other procedures in the same session paid?

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.
