Official Description

Cytopathology, cervical or vaginal (any reporting system), collected in preservative fluid, automated thin layer preparation; with manual screening and rescreening under physician supervision

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Cytopathology examination, specifically for cervical or vaginal specimens, is a diagnostic procedure aimed at identifying cellular changes that may indicate the presence of disease. This examination is crucial for detecting conditions such as cervical dysplasia and in situ carcinoma, which are precursors to invasive malignancies. The procedure is commonly known as a Papanicolaou (PAP) smear, named after Dr. George Papanicolaou, who developed this method of screening. During the test, cells are collected from the endocervix using specialized tools, such as a brush or stick, and placed in a preservative fluid to maintain their integrity for laboratory analysis. Once the specimen reaches the laboratory, it undergoes a process where the liquid cell suspension is centrifuged to eliminate debris, allowing for a concentrated sample of cervical cells. These cells are then prepared using an automated thin layer preparation system, which stains the cells and transfers them onto slides for microscopic examination. The examination process involves manual screening by a trained technician under the supervision of a physician, specifically a pathologist. In the case of CPT® Code 88143, the procedure includes not only the initial manual screening but also a rescreening process, which entails a thorough reassessment of the entire slide, potentially by a second technician. This comprehensive approach ensures that any abnormal findings are accurately identified and communicated to the treating physician, who may then recommend further diagnostic tests or follow-up procedures based on the results.

1. Indications

The cytopathology examination using CPT® Code 88143 is indicated for the following conditions:

  • Cervical Dysplasia - This condition involves abnormal changes in the cells on the surface of the cervix, which can be precursors to cervical cancer.
  • In Situ Carcinoma - This refers to cancer that is confined to the site of origin and has not invaded surrounding tissues, making early detection critical for effective treatment.
  • Routine Screening - The procedure is also performed as part of routine cervical cancer screening to monitor for any cellular changes that may require further investigation.

2. Procedure

The procedure for CPT® Code 88143 involves several key steps that ensure accurate cytopathological assessment:

  • Specimen Collection - Cells are collected from the endocervix using a specialized brush or stick. This collection method is designed to obtain a representative sample of cervical cells for analysis.
  • Preservation of Specimen - The collected specimen is immediately placed in a preservative fluid to maintain cell viability and integrity during transport to the laboratory.
  • Laboratory Processing - Upon arrival at the laboratory, the liquid cell suspension is subjected to centrifugation. This process separates the cervical cells from debris, resulting in a concentrated cell sample.
  • Automated Thin Layer Preparation - The concentrated cells are then prepared using an automated system that stains the cells and transfers them onto slides. This method enhances the quality of the slides for microscopic examination.
  • Manual Screening - A trained technician performs the initial manual screening of the prepared slides under the supervision of a physician (pathologist). This step is crucial for identifying any abnormal cellular changes.
  • Manual Rescreening - Following the initial screening, the slides undergo a manual rescreening process, which involves a complete reassessment of the entire slide. This may be conducted by a second technician to ensure thorough evaluation.
  • Communication of Findings - The results of the screening and rescreening are communicated to the treating physician. If any abnormalities are detected, the pathologist may recommend further diagnostic procedures, such as a repeat PAP smear or additional tests like colposcopy, endocervical curettage, or biopsy.

3. Post-Procedure

After the cytopathology examination is completed, the treating physician will review the findings and determine the appropriate follow-up actions. If the results indicate abnormal cellular changes, the physician may recommend a shorter interval for the next PAP smear or suggest additional diagnostic tests to further investigate the findings. It is essential for patients to adhere to follow-up recommendations to monitor their cervical health effectively and address any potential issues promptly.

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.
