What 38220 covers

A clinician advances an aspiration needle into marrow, commonly at the posterior iliac crest, and withdraws liquid marrow for diagnostic studies. Hematologists and oncologists often perform the procedure in an office, clinic, or hospital setting; interventional radiologists may perform it with image guidance when clinically needed. The aspirate can support evaluation of suspected marrow disorders, cytopenias, or hematologic malignancy. This code describes aspiration, not removal of a core tissue specimen.

Select this service when diagnostic marrow is aspirated without a marrow biopsy during the encounter. When both aspiration and biopsy are performed, use 38222 rather than separately reporting 38220 and 38221. Documentation should identify the diagnostic purpose, procedure site, and aspiration performed. CMS applies the standard multiple-procedure reduction when applicable procedures are performed in the same session: the highest-valued procedure is paid in full and others at 50%. For a bilateral procedure reported with modifier 50, CMS pays at 150%.

38220 billing questions

How is 38220 different from 38221?

38220 represents aspiration of liquid marrow for diagnostic testing; 38221 represents obtaining a core biopsy specimen. Use 38222 when both aspiration and biopsy are performed.

Can 38220 and 38221 be reported together for the same encounter?

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

Does 38220 include interpretation of the marrow specimen?

The procedure code represents obtaining the aspirate. A pathologist may separately report marrow smear interpretation, such as 85097, when that service is performed and documented.

How does CMS price bilateral aspiration?

CMS pays a bilateral procedure reported with modifier 50 at 150%. Document the bilateral procedure and report modifier 50 when appropriate.

What happens when other procedures are performed in the same session?

Under the standard multiple-procedure reduction, CMS pays the highest-valued procedure in full and the other applicable procedures at 50% when performed in the same session.

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.
