Medicare's October 2026 physician fee schedule pays G0141 $24.05 non-facility and $24.05 facility nationally, from 0.25 work, 0.46 practice-expense and 0.01 malpractice RVUs at the $33.4009 conversion factor. Qualifying APM participants get $24.17 at $33.5675. MUE limits for G0141: practitioner 1 (MAI 3, Anatomic Consideration); hospital outpatient 1 (MAI 3, Anatomic Consideration). In the NCCI PTP files v323r0 G0141 appears in 3 practitioner pairs as column 2 and 17 as column 1 (most often with 88141, G0124, P3001), and in 3 hospital outpatient pairs as column 2 and 17 as column 1. G0141 appears in no active LCD or billing and coding article, so coverage follows HCPCS coverage code C (carrier judgment, so the Medicare contractor decides coverage) and any NCD. OPPS status indicator B: Non-allowed item or service for OPPS. HCPCS record: BETOS T1H (lab tests - other (non-Medicare fee schedule)); pricing indicator 11; type of service 5 (diagnostic laboratory). 2 other active codes open with "Screening cytopathology smears"; related codes: G0147, G0148, G0140, G0138.
