What 88387 covers

A pathologist examines tissue macroscopically, selects the area needed for a nonmicroscopic analytical study, and dissects and prepares it for testing. A common situation is selecting tumor tissue from a surgical specimen for downstream molecular analysis. The preparation service is distinct from performing or interpreting the molecular assay itself and may take place in a hospital or pathology laboratory.

Report 88387 for the first specimen prepared under this service; code 88388 is used for additional specimens when appropriate. Documentation should identify the tissue and analytical purpose and support the macroscopic selection, dissection, and preparation performed. CMS treats this as a diagnostic test with professional and technical components: modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and reporting without either modifier represents 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.

88387 billing questions

How is 88387 different from 88363?

88387 covers macroscopic dissection and preparation of tissue for a nonmicroscopic study. 88363 concerns examining and selecting tissue already in an archive for molecular analysis.

When is 88388 used instead?

88387 represents preparation of the first specimen; 88388 is the related code for each additional specimen when the service is performed on more than one.

Does 88387 include the molecular assay?

No. It represents the gross tissue selection and preparation, not the downstream molecular analysis.

Which modifiers identify the components?

Use modifier 26 for the professional interpretation and TC for the technical service. Without either modifier, the claim represents the global service.

How does this differ from microdissection?

88387 describes macroscopic selection and preparation. Codes 88380 and 88381 describe laser and manual microdissection, respectively.

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.
