Official Description

Clinical pathology consultation; comprehensive, for a complex diagnostic problem, with review of patient's history and medical records

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A comprehensive clinical pathology consultation, as defined by CPT® Code 80502, is a specialized service performed by a pathologist aimed at delivering expert interpretive judgment regarding one or more test results when a complex diagnostic issue has been identified. This process involves a thorough examination of the patient's medical history and all pertinent medical records to ensure an accurate and informed assessment. The consultation is initiated through a formal written request from the attending physician, which must specifically relate to test results that deviate from expected ranges. This ensures that the pathologist is addressing significant clinical concerns that require additional expertise. Upon completion of the review, the consulting pathologist prepares a detailed written report summarizing the findings and insights, which is then provided to the requesting physician. This report serves as a critical component in guiding further diagnostic or therapeutic decisions based on the complex nature of the patient's condition.

1. Indications

The comprehensive clinical pathology consultation (CPT® Code 80502) is indicated in situations where there is a complex diagnostic problem that necessitates further interpretive judgment. The following conditions may warrant such a consultation:

  • Complex Diagnostic Issues A situation where standard test results do not provide sufficient clarity for diagnosis.
  • Abnormal Test Results Test results that fall outside of expected ranges, indicating potential underlying health concerns.
  • Need for Expert Interpretation Cases where additional expertise is required to interpret the implications of test results in the context of the patient's overall health.

2. Procedure

The procedure for a comprehensive clinical pathology consultation involves several key steps that ensure a thorough evaluation of the patient's condition. Each step is critical to the overall process:

  • Step 1: Written Request The attending physician must submit a formal written request for the consultation. This request should clearly outline the specific test results that are of concern and the reasons for seeking additional interpretive judgment from the pathologist.
  • Step 2: Review of Medical History The consulting pathologist conducts a comprehensive review of the patient's medical history. This includes examining previous diagnoses, treatments, and any relevant medical records that may provide context to the current diagnostic problem.
  • Step 3: Analysis of Test Results The pathologist analyzes the test results in detail, focusing on those that are outside the expected range. This analysis is crucial for understanding the implications of the results and how they relate to the patient's overall health status.
  • Step 4: Documentation of Findings After completing the review and analysis, the pathologist documents the findings in a written report. This report includes interpretations, insights, and any recommendations for further action or testing that may be necessary.
  • Step 5: Communication with Attending Physician The final step involves providing the written report to the requesting physician. This communication is essential for ensuring that the attending physician is informed of the findings and can make appropriate decisions regarding the patient's care.

3. Post-Procedure

After the comprehensive clinical pathology consultation is completed, the attending physician will review the findings outlined in the pathologist's report. This report may lead to further diagnostic testing, adjustments in treatment plans, or additional consultations with other specialists, depending on the insights gained from the consultation. The pathologist's recommendations, if any, will also be considered in the ongoing management of the patient's condition. It is important for the attending physician to document any follow-up actions taken as a result of the consultation to ensure continuity of care and proper tracking of the patient's health outcomes.
