What 20220 covers

Code 20220 describes sampling bone through a trocar or biopsy needle at a site classified as superficial, rather than exposing bone through an open incision. Typical targets include the ilium, sternum, ribs, and spinous processes. The service may be performed by an interventional radiologist, orthopedic surgeon, or another clinician experienced in percutaneous bone sampling, often in an imaging or procedure suite; it may also be performed in an office setting when appropriate. The purpose may be to investigate a focal lesion, suspected bone infection, or unexplained abnormality and provide tissue for pathology or microbiology.

Choose 20220 based on the bone-site category and needle or trocar approach; use 20225 for a deep site and an open bone-biopsy code when bone is exposed surgically. Documentation should identify the target bone, approach, specimen obtained, and clinical indication. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate; assistant-at-surgery payment is statutorily restricted, and co-surgeon and team-surgery reporting are not permitted.

20220 billing questions

How do I choose between 20220 and 20225?

Use 20220 for a bone site classified as superficial, such as the ilium, sternum, ribs, or spinous process. Use 20225 for a deep bone site; the distinction is not determined only by how far the needle travels.

Does 20220 include an open surgical exposure?

No. This code is for needle or trocar sampling. When the bone is exposed through an incision, consider the applicable open bone-biopsy code, such as 20240 for a superficial site.

Can imaging guidance be billed separately?

The code describes bone sampling, not image guidance itself. Separately report guidance only when a distinct guidance service is performed, documented, and meets the requirements of the applicable guidance code.

How are other procedures in the same session paid?

Under the CMS multiple-procedure rule, the highest-valued procedure is paid in full and other procedures are reduced by 50% when performed in the same session.

Can I append modifier 50 or report an assistant?

Modifier 50 is inappropriate for this code. CMS also restricts assistant-at-surgery payment and does not permit co-surgeon or team-surgery reporting.

What same-day care is included?

The 0-day global period includes same-day preoperative and postoperative care. Document the biopsy target, needle or trocar approach, specimen, and indication.

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.
