Official Description

Pathology consultation during surgery; cytologic examination (eg, touch prep, squash prep), initial site

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 88333 refers to a pathology consultation performed during surgery, specifically involving a cytologic examination at the initial site of tissue sampling. This procedure is crucial for surgeons who require immediate information regarding the presence or absence of disease, particularly malignancy, while the patient is still undergoing surgery. The pathologist conducts this examination at the request of the surgeon, utilizing techniques such as touch preparation and squash preparation to obtain cellular samples from the tissue. In the touch preparation method, the margin of the tissue sample is directly touched against a glass slide, allowing cells to adhere to the slide. This slide is then air-dried, stained, and examined microscopically to assess cellular characteristics. Alternatively, the squash preparation technique involves slicing a small portion of the tissue specimen and placing it on a slide, where it is then crushed with another slide to create a thin film. This specimen is also fixed, stained, and analyzed under a microscope. The pathologist provides an initial verbal report of the findings, which includes critical information about the presence of abnormal or malignant cells, as well as any other significant features of the cell sample. A formal written report is subsequently generated and included in the patient's medical record. For examinations of cells from the initial site, the appropriate code to use is 88333, while 88334 should be used for examinations of cells from any additional sites.

1. Indications

The procedure associated with CPT® Code 88333 is indicated in various clinical scenarios where immediate cytological evaluation is necessary. The following conditions may warrant the use of this procedure:

  • Suspicion of Malignancy The procedure is performed when there is a clinical suspicion of cancer, allowing for rapid assessment of tissue samples during surgery.
  • Assessment of Tumor Margins It is utilized to evaluate the margins of excised tumors to ensure complete removal and to check for any residual malignant cells.
  • Guidance for Surgical Decisions The cytologic examination aids surgeons in making real-time decisions regarding the extent of surgical intervention required based on the findings.

2. Procedure

The procedure for CPT® Code 88333 involves several critical steps to ensure accurate cytologic evaluation during surgery. The following outlines the procedural steps:

  • Initial Tissue Sampling The surgeon obtains a tissue sample from the surgical site, which is crucial for the subsequent cytologic examination. This sample is typically taken from areas of concern where malignancy is suspected.
  • Touch Preparation In this step, the margin of the tissue sample is gently touched against a glass slide. This contact allows cells from the tissue to adhere to the slide, creating a preliminary sample for examination.
  • Slide Preparation The slide with the adhered cells is then air-dried to preserve the cellular structure. Following this, the slide is stained using appropriate cytological stains to enhance visibility under the microscope.
  • Microscopic Examination The pathologist examines the prepared slide under a microscope, assessing the cellular characteristics to identify any abnormal or malignant cells present in the sample.
  • Initial Reporting After the examination, the pathologist provides an initial verbal report to the surgeon, detailing the findings, including the presence or absence of malignancy and any other significant cellular features.
  • Documentation A formal written report is generated, summarizing the findings of the cytologic examination. This report is then placed in the patient's medical record for future reference and continuity of care.

3. Post-Procedure

Post-procedure care following the cytologic examination under CPT® Code 88333 typically involves monitoring the patient for any immediate complications related to the surgical procedure. The surgeon may discuss the findings of the cytologic examination with the patient, particularly if any abnormal or malignant cells were identified. The written report generated by the pathologist will be reviewed in subsequent follow-up appointments to determine any further treatment or intervention needed based on the results. Additionally, the surgical team may plan additional diagnostic or therapeutic procedures if malignancy is confirmed or if further evaluation is warranted.

26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
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
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
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
XE Separate encounter, a service that is distinct because it occurred during a separate encounter
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
TC Technical component; under certain circumstances, a charge may be made for the technical component alone; under those circumstances the technical component charge is identified by adding modifier 'tc' to the usual procedure number; technical component charges are institutional charges and not billed separately by physicians; however, portable x-ray suppliers only bill for technical component and should utilize modifier tc; the charge data from portable x-ray suppliers will then be used to build customary and prevailing profiles
XP Separate practitioner, a service that is distinct because it was performed by a different practitioner
Q6 Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area
