Medigap in Brewster, WA: Medicare Supplement plans and insurers

CMS lists 61 clinicians with practice locations within 8 miles of Brewster, including 31 in primary care (family and internal medicine, nurse practitioners and physician assistants). Every one of them is listed as accepting Medicare assignment, so a Part B excess charge is unlikely for care in town. That removes the main extra risk of Plan N for local care. Within 25 miles, CMS lists clinicians in mental health, eye care, and physical therapy. Few or none practice cardiology, cancer care, orthopedics, kidney care, and neurology within 25 miles. Practices with Medicare clinicians near Brewster include Okanogan Douglas County Hospital Dist 1 and Family Health Centers.

The closest hospital to Brewster is Three Rivers Hospital in Brewster, about 2 miles away (a critical access hospital: a small rural hospital with 25 or fewer inpatient beds). Medigap has no hospital network: the Part A deductible ($1,736 in 2026) is covered the same here as anywhere.
