CPT 88325: Pathology Consultation and Surgical Case Review

CPT code 88325 covers a comprehensive pathology consultation in which a qualified provider, commonly a pathologist, reviews referred material (for example, tissue blocks or slides), relevant records and specimens, and issues a formal report. The unit of service is the surgical case regardless of the number or type of materials received. This service is critical for diagnostic accuracy in surgical pathology and for supporting downstream clinical decision-making nationally.

Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical role, typical sites where the service is delivered, and the implications for billing workflows. The publication also summarizes benchmarking context, common payer handling practices, and relevant coding considerations for pathology consultation claims.

The report is intended for revenue cycle leaders, pathology group administrators, and policy analysts. It presents actionable reference material: code definition and clinical context, payer coverage landscape, common modifiers and claim considerations (listed separately), and pointers to where stakeholders typically focus attention when submitting and adjudicating 88325 claims.

Billing Code Overview

CPT code 88325 describes a comprehensive pathology consultation in which a qualified provider, typically a pathologist, reviews referred material such as tissue blocks or slides, examines relevant records and specimens, and prepares a formal report. The consultation addresses interpretation of the referred material and formulation of diagnostic or management information for the requesting clinician.

Service type: Pathology consultation / diagnostic surgical pathology review

Typical site of service: Hospital-based pathology services, independent pathology laboratories, and outpatient surgical pathology or reference laboratory settings

Clinical Context

A 62-year-old patient with a prior hospital surgical resection of a colon mass is referred to a tertiary pathology practice for expert review of the submitted tissue slides and paraffin block. The referring facility requests a comprehensive consultation because of unusual histologic features and need for secondary opinion to guide oncology treatment. The pathologist reviews the submitted clinical records, operative report, and all slides/blocks, performs additional stains if indicated, and issues a signed consultation report. Typical workflow: receipt and accessioning of referred material, verification of clinical data, review of original and referral slides, ordering special stains or immunohistochemistry as needed, generation of a consultation report, and communication of diagnostic opinion to the referring clinician.

Typical site of service: hospital-based anatomic pathology laboratory, independent pathology reference laboratory, or outpatient pathology consulting service. Typical patient scenario: referral for second opinion on surgical pathology material following resection or biopsy, often for malignancy confirmation, margin assessment, or subspecialty interpretation (e.g., soft tissue, dermatopathology, or gastrointestinal pathology).
