Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What G0124 covers

G0124 represents physician interpretation of screening cytopathology from cervical or vaginal cells collected in preservative fluid and prepared as an automated thin layer. The specimen may come from a routine cervical screening collection; the code identifies the physician interpretation service, not the pelvic examination or specimen collection. Cytology laboratories and pathologists commonly handle this work, with the interpreting physician reviewing the prepared specimen and documenting the cytologic findings.

Select G0124 when the screening specimen follows this thin-layer workflow and physician interpretation is performed. The record should identify the cervical or vaginal specimen, its preservative-fluid preparation, and the physician’s interpretation or report. Distinguish it from G0123, which describes thin-layer cytology that is manually screened. CMS assigns work, practice expense, and malpractice relative value units to G0124.
