2025 HCPCS code G0124
(Active) Effective Date: N/A Revision Date: N/A Laboratory Services - Screening Examinations and Disease Management Training G0101-G0124 Procedures / Professional Services G0008-G9987 Feed
Screening cytopathology of the cervix or vagina using an automated thin layer preparation method, requiring physician interpretation.
Modifiers may apply depending on the circumstances of service. Consult the most recent modifier guidelines.
The medical necessity for G0124 is typically established by the patient's age, risk factors for cervical cancer (e.g., history of sexually transmitted infections, smoking), and adherence to screening guidelines.The test is indicated for early detection of precancerous and cancerous changes in the cervix and vagina.
Physician interpretation of the cytopathology smear is the primary clinical responsibility. This includes reviewing the prepared slides for abnormal cells, making a diagnosis, and generating a report.
In simple words: This code covers a lab test where a sample is taken from the cervix or vagina to check for cancer cells.The sample is prepared by a machine, and a doctor examines it under a microscope.
This HCPCS code, G0124, encompasses the screening of cytopathological smears collected from the cervix or vagina.The specimens are collected in preservative fluid and prepared using an automated thin layer preparation method.The procedure requires interpretation by a physician provider to diagnose cervical cancer or other abnormalities.
Example 1: A 21-year-old female presents for her annual well-woman exam.A Pap smear is collected using liquid-based cytology and sent to the lab for automated thin-layer preparation and physician interpretation. G0124 is reported., A 35-year-old female presents with abnormal vaginal bleeding.A Pap smear is collected and processed using an automated thin-layer preparation method. The physician interprets the results, revealing atypical squamous cells of undetermined significance (ASCUS). G0124 is reported., A 50-year-old female has a routine Pap smear performed, processed by automated thin-layer preparation. The physician reviews the slides and identifies no significant abnormalities. G0124 is reported.
