What 88381 covers

A pathology laboratory uses manual microscopic techniques to isolate a selected area or cell population from a tissue specimen. For example, a technologist may separate tumor-rich regions from surrounding non-tumor tissue in a prepared section before molecular testing. The service is distinct from gross trimming: the target is selected at the microscopic level, often with pathologist guidance, rather than by cutting the specimen at the bench based only on its gross appearance.

Report 88381 for the manual microdissection work, not for the downstream molecular assay itself. Documentation should identify the tissue and target population, support why microscopic separation was performed, and show that the work was manual rather than laser-based. CMS recognizes professional and technical components: the professional portion may be reported with modifier 26, the technical portion with modifier TC, and billing 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.

88381 billing questions

When should 88381 be chosen instead of 88380?

Use 88381 when the target tissue is separated manually under microscopic guidance. Use 88380 when laser microdissection is performed.

Does 88381 include the molecular test?

No. It represents the manual tissue preparation, not the subsequent molecular analysis; report a separately performed assay under its applicable code.

How are the professional and technical portions reported?

Modifier 26 identifies the professional portion, and modifier TC identifies the technical portion. Reporting without either modifier represents the global service.

What documentation supports reporting 88381?

Document the specimen, the target cell population or tissue area, and the manual microscopic separation performed. The record should make clear that this was not laser microdissection or gross tissue trimming.

Is 88381 used for gross selection of tissue?

No. Manual microdissection targets tissue at the microscopic level; gross examination and preparation for molecular analysis is a different service.

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.
