What 88332 covers
A pathologist uses this service during an operation to examine an additional tissue block by frozen section and provide an immediate diagnostic opinion to the surgeon. It is commonly used when further tissue is submitted to assess a margin or clarify an intraoperative finding. The work may occur in a hospital or other surgical setting with the specimen processed and examined while the procedure is underway.
Report 88332 for each additional block examined after the initial block, typically with 88331 for the first block. The operative and pathology records should support the number of distinct blocks examined and the intraoperative interpretation communicated to the surgical team. For Medicare, modifier 26 identifies the professional interpretation, modifier TC identifies the technical service, and reporting without either modifier represents the global service. CMS separately prices the 26 and TC components.

88332 billing questions
When should 88332 be reported instead of 88331?
Use 88331 for the initial tissue block in the intraoperative frozen-section consultation. Report 88332 for each additional block examined during that consultation.
Can 88332 be reported with 88331?
Yes. The additional-block service is reported with 88331 for the initial block when the pathologist examines further blocks during the same intraoperative consultation.
Which modifiers identify the components?
Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
What documentation supports multiple units?
The pathology record should identify the additional blocks examined and document the intraoperative findings or interpretation. Report a unit for each additional block supported by the record.
Is 88332 for an intraoperative cytology examination?
No. It represents additional tissue-block frozen-section work. Intraoperative cytologic examination is represented by the separate 88333 and 88334 code family.
