Laboratory pathology

About 88188: Flow cytometry interpretation, 9–15 markers

Reports a pathologist’s interpretation of flow cytometry findings when the analysis includes 9–15 markers, commonly for suspected hematologic malignancy.

This service is the professional interpretation and written report of flow cytometry findings from a panel of 9–15 markers. A pathologist or other qualified laboratory professional may evaluate results from peripheral blood, bone marrow, lymph node, or fluid specimens when assessing suspected leukemia, lymphoma, or another hematologic disorder. The report interprets the cell populations and marker pattern in the clinical context; it is not the laboratory work that processes and analyzes the specimen.

Select this code according to the number of markers included in the interpretation: 9–15. The record should support the specimen examined, markers assessed, findings, and resulting interpretation. Report the professional service separately from the applicable technical flow cytometry services; the technical portion is covered by separate codes. This code represents interpretation and reporting only.
