Qualifying APM participants get $93.99 at $33.5675. MUE limits for G0408: practitioner 1 (MAI 3, CMS Policy); hospital outpatient 1 (MAI 3, CMS Policy). In the NCCI PTP files v323r0 G0408 appears in 423 practitioner pairs as column 2 and 87 as column 1 (most often with 00100, 00102, 00103). G0408 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.

G0408 descriptor and code status

The October 2026 HCPCS Level II file describes G0408 as “Follow-up inpatient consultation, complex, physicians typically spend 35 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 "G0408 CPT code", G0408 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.
