CPT® Code 88142

CPT® Code 88142 is used to report cervical or vaginal cytopathology (Pap test) performed using an automated thin-layer preparation with manual screening by a qualified cytotechnologist or pathologist. This test is commonly used to screen for cervical cancer, precancerous lesions, and other cervical cytologic abnormalities.

The specimen is collected by the healthcare provider and processed using a liquid-based (thin-layer) preparation before being manually reviewed for abnormal cellular changes.

This code represents the cytopathology laboratory service, not the collection of the specimen, which may be reported separately when appropriate.

When to Use CPT® 88142

CPT 88142 is appropriate when:

  • Performing a Pap test using an automated thin-layer preparation with manual screening
  • Screening for cervical cancer according to established clinical guidelines
  • Evaluating patients with a history of abnormal cervical cytology
  • Monitoring patients following treatment for cervical dysplasia or other cervical abnormalities

Examples:

  • Routine cervical cancer screening during a preventive gynecologic visit
  • Follow-up Pap testing after a previously abnormal screening result
  • Surveillance of a patient with a history of cervical intraepithelial neoplasia (CIN)
  • Screening a patient with increased risk factors for cervical cancer

Documentation Requirements

To support CPT 88142 billing, documentation should include:

  • Patient identifiers and date of service
  • Clinical indication for the Pap test
  • Specimen source (cervical and/or vaginal)
  • Confirmation of automated thin-layer preparation with manual screening
  • Cytology findings and final laboratory report
  • Ordering provider information

Complete documentation supports medical necessity, preventive care reporting, and accurate laboratory billing.

Reimbursement and Coding Considerations

  • CPT 88142 applies to automated thin-layer preparation with manual screening of cervical or vaginal cytology specimens
  • Specimen collection may be reported separately when permitted by payer guidelines
  • Diagnosis coding should support preventive cervical cancer screening or diagnostic evaluation, as appropriate
  • HPV testing, if performed, is reported separately using the appropriate CPT code
  • Coverage and screening intervals vary based on payer policies and current preventive care guidelines

Always verify payer-specific laboratory and preventive screening billing requirements before submitting claims.
