What 88187 covers

Code 88187 represents the professional interpretation and written report of a flow-cytometry study evaluating 2 through 8 markers. Hematopathologists commonly perform this work to characterize abnormal cell populations in peripheral blood, bone marrow, lymph-node specimens, or body-cavity fluids when evaluating suspected leukemia, lymphoma, or another hematologic disorder. The service is the analysis and report, not specimen collection or instrument acquisition.

Select the code level based on the number of markers evaluated in the interpretation: 2 through 8 for 88187. The report should identify the specimen, describe the flow-cytometry findings, and support the interpretation and marker count. CMS identifies 88187 as professional-component-only; the technical portion is reported separately using the applicable technical code or codes, such as 88184 for the first marker and 88185 for additional markers.

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.

88187 billing questions

How does 88187 differ from 88188?

88187 applies when the interpretation evaluates 2 through 8 markers. Use 88188 for an interpretation involving 9 through 15 markers.

How does 88187 differ from 88189?

88189 is the higher marker-count interpretation level, for 16 or more markers. Choose among these interpretation codes according to the marker count documented for the study.

Does 88187 include the technical flow-cytometry work?

No. 88187 represents the professional interpretation and report; the technical portion is separately coded, typically with 88184 and any applicable units of 88185.

Should modifier 26 be appended to 88187?

CMS identifies 88187 as a professional-component-only code, so the code itself represents the interpretation and report. Do not add modifier 26 solely to identify that component.

What documentation supports reporting 88187?

Document the specimen, markers evaluated, flow-cytometry findings, and the professional interpretation. The record should support that the interpretation falls within the 2-through-8-marker range.

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.
