Mailing address
Not researched for this route
Source is the CMS Medicare Fee-for-Service Provider Enrollment Contact List (official CMS PDF listing each MAC by state), not the contractor's own page. NGS (Wellpoint Federal) home health and hospice provider enrollment line as listed by CMS. CMS lists differing mailing boxes by state (e.g., P.O. Box 7149 for New England, P.O. Box 6474 elsewhere), so no single address is recorded here; check the CMS list for your state.
