Flow cytometry
About 88185: Flow cytometry technical work, each additional marker
Report the laboratory's technical work for each flow cytometry marker beyond the first on a specimen, together with first-marker code 88184.
This code covers the laboratory work for each additional cell surface, cytoplasmic, or nuclear marker after the first in a flow cytometry study. That work includes preparing and staining cells, acquiring instrument data, and processing the results for review. A common use is immunophenotyping peripheral blood, bone marrow aspirate, lymph node, or body fluid specimens when a hematolymphoid disorder is suspected or monitored. Hospital and independent laboratories perform this technical work; a pathologist or hematopathologist may separately interpret the study.
Report one unit of 88185 for each marker beyond the first on a specimen, with 88184 for its first marker. Record the markers tested for each specimen to support the technical units. CMS treats 88185 as an add-on billed with its primary procedure and paid within that procedure's global period. It is technical-component-only, so do not append modifier 26 or TC. When separately reported, interpretation uses 88187, 88188, or 88189 according to the number of markers interpreted; the report should support that tier.

88185 billing questions
How many units of 88185 are reported for a 10-marker panel?
For one specimen, report 88184 once and nine units of 88185. If all 10 markers are interpreted, the interpretation falls in the 9-to-15-marker tier, 88188.
Can 88185 be reported without 88184?
No. Report this add-on with 88184, the primary technical code for the first marker on the specimen.
Does 88185 take modifier 26 or TC?
No. 88185 is already a technical-component-only code. A separately reported interpretation uses the applicable code from 88187 through 88189.
How are markers counted when two specimens are tested?
Count markers separately for each specimen. Report 88184 for the first marker on each specimen and 88185 units for that specimen's additional markers.
Who bills 88185 versus the interpretation code?
The laboratory performing the technical work bills 88184 and 88185. The pathologist or hematopathologist who interprets the data and issues a report bills the applicable interpretation code.
