Official Description

Cytopathology, cervical or vaginal (any reporting system), collected in preservative fluid, automated thin layer preparation; manual screening 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 a specialized instrument, 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 and concentrate the cervical cells, facilitating their retrieval for examination. The cells are then prepared using an automated thin layer preparation system, which stains the cells and transfers them onto slides, ensuring a uniform distribution for microscopic evaluation. The manual screening of these slides is conducted by a trained technician under the supervision of a physician, typically a pathologist, who oversees the accuracy of the findings. This process is essential for ensuring that any abnormal results are communicated to the treating physician, allowing for timely follow-up actions, such as repeat PAP smears or further diagnostic procedures like colposcopy or biopsy, if necessary.

1. Indications

The cytopathology examination using CPT® Code 88142 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 screening for cervical cancer in women, particularly those within the recommended age groups.

2. Procedure

The procedure for CPT® Code 88142 involves several key steps to ensure accurate cytopathological evaluation:

  • Specimen Collection - Cells are collected from the endocervix using a specialized instrument, such as a brush or stick. This step is crucial as it ensures that an adequate sample of cervical cells is obtained for analysis.
  • Preservation of Specimen - The collected specimen is immediately placed in a preservative fluid. This fluid helps maintain the cellular integrity of the sample during transport to the laboratory.
  • Laboratory Processing - Upon arrival at the laboratory, the liquid cell suspension is subjected to centrifugation. This process removes debris and concentrates the cervical cells, making them easier to analyze.
  • 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 ensures a uniform layer of cells on the slides, which is essential for accurate microscopic examination.
  • Manual Screening - The prepared slides are manually screened by a trained technician under the supervision of a physician (pathologist). This step is critical for identifying any abnormal cellular changes that may indicate disease.

3. Post-Procedure

After the cytopathology examination is completed, the findings are communicated to the treating physician. If any abnormalities are detected, the pathologist may recommend follow-up actions, which could include scheduling another PAP smear at a shorter interval than usual or conducting additional diagnostic tests such as colposcopy, endocervical curettage, or biopsy. These follow-up measures are essential for ensuring that any potential issues are addressed promptly and effectively.

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.
GA Waiver of liability statement issued as required by payer policy, individual case
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.
GC This service has been performed in part by a resident under the direction of a teaching physician
Q6 Service furnished under a fee-for-time compensation arrangement by a substitute physician or by a substitute physical therapist furnishing outpatient physical therapy services in a health professional shortage area, a medically underserved area, or a rural area
GX Notice of liability issued, voluntary under payer policy
X5 Diagnostic services requested by another clinician: for reporting services by a clinician who furnishes care to the patient only as requested by another clinician or subsequent and related services requested by another clinician; this modifier is reported for patient relationships that may not be adequately captured by the above alternative categories; reporting clinician service examples include but are not limited to, the radiologist's interpretation of an imaging study requested by another clinician
26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
91 Repeat clinical diagnostic laboratory test: in the course of treatment of the patient, it may be necessary to repeat the same laboratory test on the same day to obtain subsequent (multiple) test results. under these circumstances, the laboratory test performed can be identified by its usual procedure number and the addition of modifier 91. note: this modifier may not be used when tests are rerun to confirm initial results; due to testing problems with specimens or equipment; or for any other reason when a normal, one-time, reportable result is all that is required. this modifier may not be used when other code(s) describe a series of test results (eg, glucose tolerance tests, evocative/suppression testing). this modifier may only be used for laboratory test(s) performed more than once on the same day on the same patient.
