What 88363 covers
A pathology laboratory prepares tissue that was previously diagnosed and placed in its archive when a clinician later requests molecular testing. The work centers on locating the relevant archived material, preparing the requested tissue, and conveying it to the laboratory that will perform the molecular analysis. A pathologist or pathology laboratory staff may coordinate the preparation as part of diagnostic testing, including when the testing laboratory is separate from the archive holding the tissue.
Report one unit for each qualifying archived case, rather than counting individual slides or tissue pieces as separate cases. The record should identify the archived case, the request for molecular analysis, and the preparation and transfer of tissue. This service covers preparation and conveyance, not the molecular assay itself; code the assay separately when it is performed and separately reportable. CMS assigns this code work, practice-expense, and malpractice relative values, with practice-expense inputs that differ between office and facility settings.
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.

88363 billing questions
When is 88363 appropriate instead of an in situ hybridization code?
Use 88363 for preparing and conveying previously diagnosed, archived tissue for molecular analysis. In situ hybridization codes describe the assay performed on tissue, not this archive-preparation service.
How many units should be reported?
The code is reported per case. Do not count each slide or tissue piece as a separate case.
Does 88363 include the molecular test?
No. It describes preparation and conveyance of archived tissue; the molecular assay is a separate service when performed and separately reportable.
What documentation supports reporting 88363?
Document the previously diagnosed archived case, the request for molecular analysis, and the preparation and conveyance of tissue for that analysis.
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.
