What 88334 covers
A pathologist evaluates cytologic material from an additional site during surgery, often using a touch preparation or another rapid preparation to assess material while the procedure is underway. The result can help the surgical team make an immediate decision about the specimen or whether additional tissue is needed. This service is typically performed in connection with an operation, with laboratory staff preparing the material and the pathologist interpreting it.
Report 88334 with 88333 when the pathologist examines cytologic material from an additional site; the initial site is reported with 88333. Documentation should identify the sites examined and support a separate intraoperative evaluation for each additional site, rather than merely counting slides or preparations from one site. CMS classifies 88334 as an add-on billed with a primary procedure and paid within that procedure’s global period. Modifier 26 identifies the interpretation, modifier TC identifies the technical service, and an unmodified claim 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.

- 88331Frozen sectionFirst block, one specimen
- 88331 reports intraoperative frozen-section examination of the initial tissue block. Choose 88334 when the additional evaluation is cytologic and site-based.
- 88332Frozen sectionEach additional tissue block
- 88332 is for each additional tissue block examined by frozen section; 88334 is for each additional site evaluated cytologically.
- 88329Pathology consultGross examination only
- 88329 describes an intraoperative pathology consultation based on gross examination. 88334 applies when the additional intraoperative evaluation is cytologic.
88334 billing questions
When should 88334 be reported instead of 88333?
88333 reports the initial cytologic site examined during surgery. Report 88334 for each additional site evaluated in that intraoperative consultation.
Does each slide or preparation count as another unit?
No. The distinction is based on additional sites examined, not the number of slides or preparations from the same site. Document the site associated with each additional evaluation.
Can 88334 be billed by itself?
No. It is an add-on code and is reported with the primary procedure, typically 88333 for the initial intraoperative cytologic site.
When are modifiers 26 and TC used?
Use modifier 26 for the pathologist’s interpretation and modifier TC for the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
How does 88334 differ from frozen-section codes 88331 and 88332?
88334 is for additional-site cytologic evaluation during surgery. Codes 88331 and 88332 report intraoperative examination of tissue blocks using frozen sections.
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.
