Official Description

Cytopathology, slides, cervical or vaginal; manual screening under physician supervision

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

CPT® Code 88150 refers to the process of cytopathology specifically for cervical or vaginal specimens, where manual screening is conducted under the supervision of a physician. This procedure is primarily associated with conventional Papanicolaou (PAP) smears, which are critical in the early detection of cervical abnormalities. The PAP smear is a test that involves collecting cells from the cervix using a specialized instrument, such as a brush or stick, to gather samples from the endocervix. These samples are then smeared onto a glass slide, fixed, and sent to a cytology laboratory for further analysis. The laboratory technician stains the slide and examines it under a microscope to identify any cellular abnormalities that may indicate conditions such as cervical dysplasia or in situ carcinoma. The significance of this procedure lies in its ability to detect precancerous changes, allowing for timely monitoring and intervention before the development of invasive cancer. The manual screening performed under CPT® Code 88150 involves a trained technician reviewing the slide for abnormalities, with the oversight of a physician, ensuring that any potential issues are accurately identified and addressed. This code is distinct from other related codes that involve computer-assisted screening or additional manual rescreening processes, emphasizing the importance of direct human oversight in the diagnostic process.

1. Indications

The procedure associated with CPT® Code 88150 is indicated for the following conditions:

  • Cervical Dysplasia - The presence of abnormal cells on the cervix that may indicate a precancerous condition.
  • In Situ Carcinoma - A type of cancer that is confined to the site of origin and has not invaded surrounding tissues.
  • Routine Screening - Regular monitoring of cervical health in women to detect any changes that may require further investigation or treatment.

2. Procedure

The procedure for CPT® Code 88150 involves several key steps that ensure the accurate collection and analysis of cervical or vaginal specimens:

  • Step 1: Specimen Collection - Cells are collected from the endocervix using a specialized instrument, such as a brush or stick. This step is crucial as it gathers the necessary cellular material for examination.
  • Step 2: Slide Preparation - The collected specimen is smeared onto a glass slide. The slide is then fixed using a spray or immersion method to preserve the cellular structure for microscopic evaluation.
  • Step 3: Staining - The prepared slide is sent to a cytology laboratory where it undergoes staining. This process enhances the visibility of the cells under a microscope, allowing for better identification of abnormalities.
  • Step 4: Manual Screening - A trained technician manually screens the stained slide under a microscope. This step is performed under the supervision of a physician, ensuring that any abnormalities are accurately identified and documented.
  • Step 5: Reporting Findings - The technician notes any abnormal cells or cell clusters observed during the screening. The findings are then communicated to the treating physician for further evaluation and potential follow-up actions.

3. Post-Procedure

After the procedure associated with CPT® Code 88150, the following post-procedure considerations are important:

Results from the manual screening are typically communicated to the treating physician, who will review the findings. If any abnormalities are detected, the physician may recommend additional follow-up procedures, such as a repeat PAP smear at a shorter interval, colposcopy, endocervical curettage, or biopsy to further investigate the findings. It is essential for the physician to discuss the results with the patient and outline any necessary next steps based on the findings of the cytopathology report.

90 Reference (outside) laboratory: when laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 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.
