Official Description

Pathology consultation during surgery;

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 88329 refers to a pathology consultation that occurs during a surgical procedure. This service is specifically requested by the surgeon and involves the examination of a tissue block to ascertain the presence or absence of disease, including malignancy. The primary goal of this consultation is to provide immediate information that can influence surgical decisions, particularly regarding the adequacy of surgical margins. A tissue block is defined as a sample of tissue that has been prepared and submitted as a single specimen for pathological examination. The process begins with a gross examination of the tissue block, which allows the pathologist to assess the overall characteristics of the specimen. Following this initial assessment, the tissue block is subjected to a process known as flash freezing, which preserves the cellular structure for further analysis. The frozen tissue is then sliced into thin sections, enabling detailed microscopic examination. During this evaluation, the pathologist is tasked with identifying any neoplasms or other diseases present, determining the extent of involvement, and assessing whether the surgical margins are free of disease. An initial verbal report is provided to the surgical team, summarizing critical findings such as the presence of neoplasm, the extent of disease involvement, and any other significant characteristics of the tissue sample. Additionally, a comprehensive written report is generated and included in the patient's medical record, ensuring that all findings are documented for future reference. It is important to note that CPT® Code 88329 is specifically for the pathology consultation during surgery without the examination of a tissue block. For the examination of the first tissue block and all frozen sections derived from it, CPT® Code 88331 should be utilized, while CPT® Code 88332 is designated for each additional tissue block with frozen sections.

1. Indications

The pathology consultation during surgery, represented by CPT® Code 88329, is indicated in various clinical scenarios where immediate pathological assessment is crucial. The following conditions may warrant this procedure:

  • Presence of Tumors The surgeon may request a consultation to determine if a tumor is malignant or benign, which can significantly influence surgical decisions.
  • Assessment of Surgical Margins The procedure is indicated when there is a need to evaluate whether the surgical margins are free of disease, ensuring complete removal of malignant tissue.
  • Uncertain Diagnosis In cases where the diagnosis is unclear, a pathology consultation can provide critical information to guide further treatment.
  • Intraoperative Decision-Making The need for real-time information during surgery to make immediate decisions about the extent of resection or additional interventions.

2. Procedure

The procedure for CPT® Code 88329 involves several key steps that ensure a thorough examination of the tissue block during surgery. The following outlines the procedural steps:

  • Step 1: Request for Consultation The surgeon initiates the process by requesting a pathology consultation during the surgical procedure, indicating the need for immediate pathological evaluation.
  • Step 2: Gross Examination Upon receiving the tissue block, the pathologist performs a gross examination, assessing the overall characteristics of the specimen to identify any visible abnormalities.
  • Step 3: Flash Freezing The tissue block is then flash frozen to preserve its cellular architecture, which is essential for accurate microscopic analysis.
  • Step 4: Sectioning The frozen tissue is sliced into thin sections, allowing for detailed microscopic examination of the cellular structure and any pathological changes.
  • Step 5: Microscopic Examination The pathologist examines the thin sections microscopically to identify the presence of neoplasms, assess the extent of disease involvement, and evaluate the surgical margins.
  • Step 6: Initial Verbal Report After the examination, the pathologist provides an initial verbal report to the surgical team, summarizing critical findings such as the presence of disease and the status of surgical margins.
  • Step 7: Written Report Finally, a comprehensive written report is generated, detailing the findings and conclusions, which is then placed in the patient's medical record for future reference.

3. Post-Procedure

After the pathology consultation during surgery, the pathologist's findings are crucial for guiding the surgical team's next steps. The initial verbal report allows for immediate decision-making regarding the surgical approach, such as whether additional tissue needs to be removed or if the procedure can proceed as planned. The written report, which is documented in the medical record, serves as a formal account of the findings and is essential for ongoing patient management and follow-up care. It is important for the surgical team to review the report thoroughly to ensure that all relevant information is considered in the patient's treatment plan. Additionally, any further actions or interventions based on the pathology findings should be documented appropriately in the patient's medical record.

59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
GC This service has been performed in part by a resident under the direction of a teaching physician
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
