What G0147 covers
G0147 identifies automated screening of cytopathology smears from the cervix or vagina. A cytology laboratory uses an automated system to screen cells for abnormalities under physician supervision. The service is used for cervical cytology screening. Other related codes identify automated screening with physician involvement or rescreening, or a thin-layer preparation.
Report G0147 for the automated screening service. Medicare pays it under the CLFS at one national amount per code, applicable across localities and without an office-versus-facility adjustment. The 2026 national CLFS amount is $18.54. The national amount has risen each year from 2020 through 2026. G0147 is paid only through the CLFS, with no separate physician-fee-schedule payment for an interpretation component.

How Medicare pays G0147
Clinical lab tests aren’t priced like physician services. They’re paid from their own fee schedule, with its own rules. See the whole lab fee schedule.
One national amount
CMS sets a single Clinical Laboratory Fee Schedule amount for G0147. There’s no geographic (GPCI) adjustment, so it pays the same in every state and payment locality.
No office or facility rate
Lab tests aren’t built from relative value units, so there’s no office and facility split: the place of service doesn’t change the CLFS amount.
Updated every quarter
CMS republishes the CLFS each quarter. New tests, often proprietary laboratory analyses (PLA codes), join during the year; existing amounts are updated each January.
Excluded from the physician fee schedule
The physician fee schedule lists G0147 with status X (excluded by statute), so the test itself is paid only from the CLFS.
