What 85097 covers

A physician, commonly a pathologist or hematopathologist, examines bone marrow material and documents findings that help diagnose or classify conditions such as leukemia, myelodysplastic syndromes, plasma cell disorders, and unexplained cytopenias. The material may include aspirate smears or a marrow biopsy. The interpretation is a diagnostic service, not the collection of the specimen.

Report 85097 for the physician’s marrow interpretation when that service is separately performed and documented. The record should identify the material reviewed, the clinical question, and the physician’s interpretive findings in a signed report. If aspiration, biopsy, and smear interpretation are reported together under 38222, the interpretation is included in that combined service; do not separately report 85097 for the same interpretation. A separately examined core biopsy may also have a surgical pathology service reported when supported by the work performed.

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.

85097 billing questions

Is 85097 used to collect the marrow specimen?

No. It reports the physician’s interpretation of marrow material; aspiration and biopsy collection are represented by separate procedure services.

How does 85097 differ from 38222?

85097 reports interpretation alone. Code 38222 represents combined marrow aspiration and biopsy with smear interpretation, so the same interpretation should not be separately reported as 85097.

Can 85097 be reported with a marrow biopsy pathology service?

It may be reported with a separate surgical pathology examination when the core biopsy tissue is separately examined and the documentation supports both services.

What documentation supports 85097?

Keep the marrow material reviewed, the diagnostic reason for the study, and a signed report of the physician’s microscopic interpretation.

Should 85097 be used for a peripheral blood smear?

No. 85097 concerns bone marrow material; 85060 is the related interpretation service for a peripheral blood smear.

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.
