What 88291 covers

A qualified interpreting professional reviews results from cytogenetic or molecular cytogenetic testing, interprets the findings, and prepares a report. The studies may involve chromosome analysis or molecular cytogenetic methods such as DNA-probe testing. These services are commonly performed through clinical laboratories serving hospitals, physician practices, and other diagnostic settings; the interpretation may inform evaluation of suspected chromosomal abnormalities or other genetic conditions.

Report 88291 for the interpretation and report, not for specimen processing or the laboratory testing itself. The documentation should support the study reviewed, the interpreting professional’s findings, and the resulting report. CMS identifies 88291 as a professional-component-only code; the technical portion is reported separately using the code for the test performed. Select that technical code according to the method and study, such as DNA-probe testing or chromosome analysis. The professional interpretation and the technical service may therefore appear as separate lines for the same study.

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.

88291 billing questions

How is 88291 different from 88271?

88291 represents interpretation and reporting. 88271 describes DNA-probe testing, the technical service, when that method is performed.

Does 88291 include laboratory testing or specimen processing?

No. CMS identifies 88291 as professional-component-only; the technical portion is coded separately based on the cytogenetic method performed.

What documentation supports reporting 88291?

Keep the interpreted study results and the written report documenting the professional findings. The record should identify the study being interpreted.

Can 88291 be reported with chromosome analysis?

Yes, when the professional interpretation and report are performed for a chromosome analysis study. Report the applicable technical service separately.

Does 88291 represent a count of cells or probes?

No. It represents the interpretation and report; cell counts or probe details belong to selection of the separate technical study code.

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.
