What 88184 covers

A laboratory performs the technical work to analyze the first cell-surface, cytoplasmic, or nuclear marker in a flow-cytometry study. This testing is commonly part of immunophenotyping to characterize abnormal cell populations in blood, bone marrow, or another submitted specimen. Laboratory personnel prepare and run the specimen on a flow cytometer; a qualified professional interprets the findings separately.

Report 88184 for the first marker, with 88185 for each additional marker when performed. The record should identify the specimen and markers tested and support the technical work performed. CMS classifies 88184 as technical-component-only: it covers laboratory processing and analysis, not the professional interpretation. Report the appropriate interpretation code separately based on the number of markers interpreted; 88187, 88188, and 88189 cover different marker-count ranges.

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.

88184 billing questions

When should 88184 be reported instead of 88185?

Use 88184 for the first marker in the flow-cytometry study. Use 88185 for each additional marker.

Does 88184 include the professional interpretation?

No. It represents the technical work only; the interpretation is reported separately with the applicable flow-cytometry reading code.

Which interpretation code is paired with 88184?

The interpretation code depends on the number of markers interpreted: 88187 covers 2–8, 88188 covers 9–15, and 88189 covers 16 or more.

What documentation supports reporting 88184?

Document the specimen, the marker panel tested, and the laboratory technical work performed. The record should make clear which marker was the first in the study.

Can 88184 be reported for every marker tested?

No. Report 88184 for the first marker; report 88185 for each additional marker.

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.
