What 88314 covers
A Group III histochemical stain is an additional tissue preparation used to bring out features that help a pathologist evaluate a biopsy or other surgical specimen. Laboratory histotechnologists perform the staining, and a pathologist interprets the result in the context of the specimen and issues the diagnostic report. The stain may be used when routine hematoxylin-and-eosin sections leave a specific tissue characteristic unclear; the stain must fall within the CPT Group III classification.
Report 88314 for each applicable stain, with documentation identifying the stain, the tissue examined, and the diagnostic reason for using it. It is an add-on to the pathology service, not a substitute for the primary examination of the specimen. CMS recognizes professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the laboratory work, and no modifier reports the global service. CMS separately prices both component modifiers.
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.

88314 billing questions
When should 88314 be selected instead of 88312 or 88313?
Select 88314 when the stain performed belongs to CPT Group III. The stain’s CPT group, rather than the specimen type or the reason for testing alone, distinguishes it from Groups I and II.
Can 88314 be reported by itself?
No. It is an add-on stain service reported with the related primary pathology service, such as a surgical pathology examination, when that examination and the stain are documented.
What supports reporting 88314?
The record should identify the Group III stain, the specimen or tissue examined, and the clinical or diagnostic question the stain helps address. The pathology report should include the interpretation.
How are the professional and technical components reported?
Use modifier 26 for the pathologist’s interpretation and modifier TC for the technical laboratory work. Report without either modifier when billing the global service.
Is 88314 counted per slide or per stain?
The code is reported for each applicable stain, not simply for each slide or tissue section. Documentation should make the stain performed identifiable.
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.
