Official Description

Cytopathology, slides, cervical or vaginal (the Bethesda System); with manual screening and rescreening under physician supervision

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 88165 refers to a specific cytopathology procedure involving the analysis of cervical or vaginal slides using the Bethesda System. This procedure is commonly known as a Papanicolaou (PAP) smear, which is a critical screening tool for detecting cervical cancer and other abnormalities in cervical cells. The Bethesda System is the predominant reporting framework utilized in the United States for interpreting PAP smear results. It provides a standardized method for reporting the adequacy of the specimen collected, identifying any signs of infection, and categorizing cellular changes. These changes may include benign alterations, atypical squamous cells of undetermined significance (ASCUS), atypical glandular cells of undetermined significance (AGCUS), and various degrees of dysplasia or squamous intraepithelial lesions (SIL), which are further classified into low-grade (LGSIL) and high-grade (HGSIL) lesions, as well as carcinoma. During the procedure, cells are collected from the endocervix using a specialized brush or stick, and the specimen is then smeared onto a glass slide. The slide is fixed using either a spray or immersion technique and subsequently covered with a coverslip. Once prepared, the slide is sent to a cytology laboratory for staining. A trained technician screens the slide under a microscope to identify any abnormalities in the cells. In the context of CPT® Code 88165, the technician performs a manual screening of the slide while under the supervision of a physician. This code also includes a rescreening process that utilizes computer assistance to enhance the detection of suspicious single cells and abnormal cell structures. The technician reviews the findings from both the manual and computer-assisted screenings to ensure a comprehensive evaluation of the specimen. This thorough approach is essential for accurate diagnosis and subsequent management of any identified abnormalities.

1. Indications

The procedure associated with CPT® Code 88165 is indicated for the following conditions:

  • Cervical Cancer Screening This procedure is primarily performed as a routine screening for cervical cancer in women.
  • Detection of Abnormal Cervical Cells It is used to identify atypical squamous cells of undetermined significance (ASCUS) and atypical glandular cells of undetermined significance (AGCUS).
  • Monitoring of Known Abnormalities The procedure may be indicated for patients with a history of cervical dysplasia or other abnormalities to monitor changes over time.
  • Evaluation of Symptoms It is performed in patients presenting with symptoms such as abnormal vaginal bleeding or discharge, which may warrant further investigation of cervical health.

2. Procedure

The procedure for CPT® Code 88165 involves several detailed steps to ensure accurate cytological evaluation:

  • Specimen Collection Cells are collected from the endocervix using a specialized brush or stick. This step is crucial as it ensures that an adequate sample of cervical cells is obtained for analysis.
  • Slide Preparation The collected specimen is smeared onto a glass slide. The slide is then fixed using either a spray or immersion technique to preserve the cellular structure for microscopic examination.
  • Staining After preparation, the slide is sent to a cytology laboratory where it undergoes a staining process. This step enhances the visibility of the cells under a microscope, allowing for better identification of abnormalities.
  • Manual Screening A trained technician performs a manual screening of the slide under a microscope. This initial screening is conducted under the supervision of a physician, ensuring that any potential abnormalities are identified.
  • Computer-Assisted Rescreening Following the manual screening, the slide is subjected to a computer-assisted rescreening process. The computer is programmed to detect suspicious single cells and abnormal cell structures, providing an additional layer of analysis.
  • Comparison of Findings The technician reviews the findings from both the manual and computer-assisted screenings. This comparison is essential for confirming any abnormalities and ensuring a thorough evaluation of the specimen.
  • Communication of Results The findings from the screening are communicated to the treating physician. If any abnormalities are detected, the pathologist may recommend further testing or follow-up procedures, such as a repeat PAP smear or additional diagnostic tests.

3. Post-Procedure

After the procedure associated with CPT® Code 88165, the patient may be advised on several post-procedure considerations. The results of the PAP smear are typically communicated to the treating physician, who will discuss the findings with the patient. If the results indicate abnormal cells, the physician may recommend a follow-up PAP smear at a shorter interval than usual or suggest additional diagnostic tests, such as colposcopy, endocervical curettage, or biopsy, to further evaluate the cervical health. Patients may also be advised to monitor for any unusual symptoms, such as abnormal bleeding or discharge, and to maintain regular gynecological check-ups as part of their ongoing health care.
