What 88305 covers
This service covers gross examination and microscopic interpretation of a Level IV tissue specimen, with routine processing, embedding, sectioning, and H&E staining. Common specimens include skin biopsies, gastric and colon biopsies, colorectal polyps, breast core biopsies, endometrial biopsies, and bone marrow core biopsies. Pathologists, including dermatopathologists, examine these specimens in hospital laboratories, independent laboratories, or physician office laboratories.
Report one unit for each separately submitted specimen classified at Level IV; the specimen type, not the number of tissue blocks or slides, determines the level. The pathology report should identify each specimen and its anatomic site, gross findings, and microscopic diagnosis. Separately performed and documented special stains, immunohistochemistry, or decalcification may be reported with the appropriate codes when medically necessary. Without a modifier, 88305 represents the global service. Modifier 26 identifies the pathologist's interpretation and report; modifier TC identifies technical processing, equipment, and staff work. For Medicare prostate needle biopsies, report G0416 for the biopsy case rather than 88305 units for individual cores or specimens.

Where the Wyoming rate applies
Wyoming is a Medicare payment area, not a city. Our Census mapping connects it to 205 cities and communities in Wyoming. Some span more than one payment area; confirm with the service ZIP.
88305 billing questions
How many units are reported when a patient has several biopsies?
Report one unit for each separately submitted specimen, such as biopsies from different colon sites submitted in distinct containers. Multiple pieces of tissue submitted together as one specimen count as one unit.
When is modifier 26 appended?
Append 26 when the pathologist bills only the interpretation, such as when a hospital laboratory processes the slides. The entity billing only the technical work uses TC; an entity billing both components uses no component modifier.
Are special stains or immunostains included?
Routine H&E staining is included. Separately performed and documented special stains (88312, 88313), immunohistochemistry (88342, 88341), or decalcification (88311) may be reported when medically necessary.
How is a Medicare prostate needle biopsy reported?
Report one unit of G0416 for the prostate needle biopsy case, regardless of the number of cores or specimens, rather than per-specimen 88305.
Can a skin cyst be billed at this level?
Skin cysts, tags, and debridements are assigned to Level III (88304). Select 88305 for skin biopsies and excisions classified at Level IV rather than assigning a level based on whether margins are assessed.
What documentation supports the level?
The report should identify each specimen separately, include gross findings and the microscopic diagnosis, and specify the anatomic site so the specimen type supports the Level IV assignment.
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.
