Summary & Overview
CPT 88147: Automated Cervical or Vaginal Cytology Screening
CPT code 88147 identifies a technical laboratory screening for cervical or vaginal cytopathology performed by a laboratory analyst using an automated system under physician supervision. Nationally, this code is used in cytology workflows for population screening, specimen triage, and as part of laboratory quality and throughput strategies. It matters because automated screening impacts laboratory staffing, equipment utilization, and coding accuracy tied to preventive care pathways.
Key payers in standard analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for automated cytology screening, typical sites of service, and payer coverage considerations. The publication covers benchmark metrics and common modifier usage for claim adjudication, outlines relevant policy and coding updates affecting lab technical services, and summarizes how CPT code 88147 interacts with laboratory billing workflows. This resource is intended to help billing managers, laboratory directors, and compliance staff understand usage patterns and administrative considerations for automated cervical and vaginal cytology screening at a national level.
Billing Code Overview
CPT code 88147 describes a laboratory screening test in which a laboratory analyst performs the technical component of an automated cervical or vaginal cytopathology smear under a physician’s supervision. This code applies to one screening performed using an automated system.
Service type: Laboratory screening (cytopathology), automated
Typical site of service: Clinical laboratory or hospital laboratory
Clinical & Coding Specifications
Clinical Context
A 32-year-old patient presents to a women's health clinic for routine cervical cancer screening. A clinician obtains a cervical/vaginal cytology specimen (Pap smear) during the pelvic exam and places the specimen into the laboratory’s collection medium. The specimen is accessioned in the cytology laboratory where a lab technologist or cytotechnologist prepares the sample for automated slide screening. Under the supervision of a pathologist, the laboratory uses an automated screening system to perform one technical screening pass of the cervical/vaginal cytology smear. If the automated system flags abnormalities or the technologist notes atypia, the case is reviewed by cytology staff and the pathologist for microscopic interpretation and final diagnosis. Typical sites of service include outpatient ambulatory clinics, physician offices, and independent or hospital-based clinical laboratories.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Standard office or outpatient service | Use when the service is the usual, default professional service without unusual complexity. |
26 | Professional component | Use when reporting the professional interpretation component by the pathologist separate from the technical screening (technical component billed by lab). |
