Summary & Overview
CPT 88331: Intraoperative Pathology Consultation
CPT code 88331 represents an intraoperative or pathological consultation performed during surgery to provide immediate diagnostic or prognostic information that guides a surgeon's decision to continue, modify, or stop a procedure. Nationally, this code is important because timely pathology input can change intraoperative management and influence downstream outcomes and resource use. The code applies to services rendered in the operating room or other intraoperative settings where rapid pathology interpretation is needed.
Key payers typically included in analyses are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national benchmarks for utilization and common payer coverage patterns, an explanation of clinical context and appropriate sites of service, and discussion of coding and billing considerations relevant to intraoperative pathology consultations. The publication summarizes typical service delivery, common modifiers in use (provided separately), and where to locate appropriate documentation standards.
This executive summary orients clinicians, coding staff, and payers to the operational and clinical significance of CPT code 88331, clarifying when the service is performed and what stakeholders should expect in terms of service type and setting. Data not available in the input will be noted in detail sections.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient is taken to the operating room for a partial colectomy for a suspicious segmental colonic mass identified on preoperative imaging and colonoscopy. During surgery, the operating surgeon requests an intraoperative (frozen section) pathological consultation to determine margin status and to assess whether the lesion represents invasive carcinoma versus a benign or in situ process. The pathology team performs a rapid frozen section of the tissue specimen in the surgical pathology suite adjacent to the OR and communicates immediate diagnostic and margin information to the surgeon. Based on the consultation, the surgeon decides whether to extend resection, perform additional lymph node sampling, or proceed to reconstruction. Typical workflow steps: the surgeon communicates the clinical question and specimen labeling in the OR; specimen transport to the frozen section room; immediate gross examination, freezing, sectioning, microscopic interpretation by the pathologist; verbal report to the surgeon; and documentation of the intraoperative consultation in the pathology report and operative record.
