What 88358 covers
A pathologist uses manual morphometric methods to measure or evaluate features of tumor cells in a tissue specimen. A recognized example is analysis of tumor DNA ploidy. This is a specialized pathology service, not the routine microscopic examination used to diagnose and classify a biopsy or resection. It is generally performed in a pathology laboratory, with the pathologist interpreting the analysis and laboratory staff supporting the technical work.
Report the code when the documented tumor analysis is performed manually; distinguish it from computer-assisted tumor morphometry and from quantitative assessment of immunohistochemical staining. The record should identify the tumor material examined, the analysis performed, and the pathologist’s findings or interpretation. CMS recognizes a professional component for interpretation and a technical component for equipment and staff. Report modifier 26 for the professional component, modifier TC for the technical component, or neither modifier when billing the global service.
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.

88358 billing questions
How does this differ from computer-assisted tumor morphometry?
This code is for manual morphometric analysis. Use the computer-assisted sibling when the tumor measurement is performed with computer assistance.
Is routine tumor microscopy included in this service?
No. This code represents a specialized morphometric analysis, such as manual assessment for DNA ploidy, rather than routine microscopic examination of a biopsy or resection.
Which modifiers identify the professional and technical components?
Use modifier 26 for the pathologist’s interpretation and modifier TC for the equipment and staff component. Submit without either modifier for the global service.
What documentation supports reporting this code?
Document the tumor specimen or material analyzed, the manual morphometric method and purpose, and the resulting findings or interpretation.
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.
