Qualifying APM participants get $36.25 at $33.5675. CMS caps G0406 at practitioner 1 (MAI 3, CMS Policy); hospital outpatient 1 (MAI 3, CMS Policy) units per day in the 2026 Q4 MUE tables. In the NCCI PTP files v323r0 G0406 appears in 435 practitioner pairs as column 2 and 75 as column 1 (most often with 00100, 00102, 00103). G0406 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. It is on the CY2026 Medicare telehealth list (CMS action: Maintain). OPPS status indicator B: Non-allowed item or service for OPPS. HCPCS record: BETOS M6 (consultations); pricing indicator 13; type of service 3 (consultation). 2 other active codes open with "Follow-up inpatient consultation"; related codes: G0407, G0408, G0405, G0404.

G0406 descriptor and code status

The October 2026 HCPCS Level II file describes G0406 as “Follow-up inpatient consultation, limited, physicians typically spend 15 minutes communicating with the patient via telehealth”. It sits in the G section (procedures and professional services, temporary), listed with the other G codes. Although searches often call it the "G0406 CPT code", G0406 is a HCPCS Level II code maintained by CMS, not an AMA CPT code; both go in the same procedure-code field on the claim.
