About 88369: Computer-assisted ISH morphometric analysis
Reports computer-assisted quantitative or semiquantitative morphometric analysis of in situ hybridization, such as probe-based FISH testing.
This service uses computer-assisted image analysis to quantify or semiquantify signals in tissue cells examined by in situ hybridization, including fluorescence in situ hybridization (FISH). A pathologist or laboratory specialist may evaluate probe signals to assess a molecular finding such as gene amplification in a tumor specimen. It is distinct from simply performing or interpreting a routine histologic stain; the work is the morphometric analysis of the ISH result.
Report 88369 as an add-on with the required primary procedure, not by itself; CMS pays it within that procedure’s global period. The record should identify the specimen and probe, describe the computerized quantitative or semiquantitative analysis, and support the reported interpretation. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical work, including equipment and staff. Reporting without either modifier represents the global service.

- Global period
- Add-on code: billed only together with a primary procedure and paid within that procedure's global period.
- Professional and technical components
- Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

88369 billing questions
Can 88369 be reported by itself?
No. CMS identifies it as an add-on code, so it must be billed with a primary procedure and is paid within that procedure’s global period.
When should 88369 be distinguished from 88373?
88369 is for the initial single-probe stain procedure in this morphometric analysis series. 88373 is for each additional single-probe stain procedure.
How are modifiers 26 and TC used?
Use modifier 26 for the professional interpretation and modifier TC for the technical service. Without either modifier, the claim represents the global service.
What documentation supports 88369?
Document the specimen and probe evaluated, the computer-assisted quantitative or semiquantitative analysis performed, and the resulting interpretation.
Is 88369 a test for routine immunohistochemistry?
No. It describes morphometric analysis of in situ hybridization. Tumor immunohistochemistry analysis is represented by a different code family.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
