What 38221 covers

A clinician obtains a core of marrow through a needle or trocar, most often from the posterior iliac crest, to evaluate suspected or known marrow disease. Hematologists and oncologists commonly perform the procedure in an office, clinic, or hospital setting, often using local anesthesia. Typical indications include unexplained cytopenias, suspected leukemia or lymphoma, plasma cell disorders, and assessment of marrow involvement. The specimen is sent for pathologic evaluation.

Report 38221 when a diagnostic core biopsy is performed without aspiration; when both biopsy and aspiration are performed, use 38222 instead. Documentation should identify the indication, biopsy site and side, and the procedure performed. For bilateral biopsies, CMS pays 150% when modifier 50 is reported. When this service and another procedure subject to the multiple-procedure rule are performed in the same session, the highest-valued procedure is paid in full and the others at 50%.

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.

38221 billing questions

When should 38221 be chosen over 38222?

Use 38221 for a diagnostic marrow core biopsy without aspiration. When both a biopsy and aspiration are performed, report 38222.

Can marrow aspiration be reported separately with 38221?

When aspiration and biopsy are both performed, use 38222 rather than separately reporting 38220 with 38221.

How is a bilateral bone marrow biopsy reported?

Report modifier 50 for a bilateral procedure; CMS pays 150%. Document the biopsy at both sites.

What documentation supports 38221?

Document the diagnostic indication, the site and side sampled, and that a needle or trocar core biopsy was performed without aspiration.

How does the multiple-procedure reduction affect 38221?

When another procedure subject to the rule is performed in the same session, the highest-valued procedure is paid in full and the others at 50%.

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.
