What 88311 covers
A histology laboratory decalcifies bone and other calcified tissue by removing mineral that would prevent the specimen from being cut into thin sections. This preparation may be needed for a bone biopsy, a bone-containing tumor specimen, or another calcified tissue sample before microscopic evaluation. Laboratory personnel generally perform the processing; a pathologist interprets the resulting tissue examination as part of the diagnostic workup.
Report 88311 when decalcification is performed, alongside the applicable surgical pathology examination when that specimen is also examined. The record should identify the specimen and support why decalcification was needed; the pathology report documents the diagnostic examination. CMS recognizes professional and technical components: modifier 26 identifies the professional interpretation, modifier TC identifies the technical work, and billing without either modifier represents the global service. The professional and technical components are separately priced.
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.

88311 billing questions
Is 88311 the surgical pathology examination of the specimen?
No. It reports decalcification preparation; the surgical pathology code represents the examination and diagnostic work on the specimen.
Can 88311 be reported with a surgical pathology code?
Yes, when decalcification is performed and the same specimen also receives a surgical pathology examination. Select the examination code for the specimen and service documented.
Which modifier identifies the pathologist's work?
Modifier 26 identifies the professional interpretation. Modifier TC identifies the technical work, and no modifier represents the global service.
What should the record support?
Document the tissue specimen, the decalcification performed, and the associated microscopic examination when one is reported. The pathology report should support the diagnostic work.
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.
