What G0145 covers
G0145 identifies screening cytopathology of a cervical or vaginal specimen collected in preservative fluid and prepared as a thin layer. The laboratory uses an automated system for initial screening, then manually rescreens the specimen under physician supervision. This code describes a cervical or vaginal screening cytology service.
Report G0145 for this screening workflow. Medicare pays the test through the Clinical Laboratory Fee Schedule (CLFS), with no separate physician fee schedule payment for the test. The 2026 national CLFS amount is $26.49 and has been unchanged since 2020. One national amount applies in every locality, with no geographic or office-versus-facility adjustment.

How Medicare pays G0145
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 G0145. 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 G0145 with status X (excluded by statute), so the test itself is paid only from the CLFS.
