Medigap in Mabton, WA: Medicare Supplement plans and insurers

CMS lists 65 clinicians with practice locations within 8 miles of Mabton, including 37 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, physical therapy, general surgery, eye care, chiropractic, orthopedics, and foot care. Few or none practice cancer care, kidney care, and neurology within 25 miles. Practices with Medicare clinicians near Mabton include Yakima Valley Farm Workers Clinic and Columbia Physical Therapy Inc. PS.

The closest hospital to Mabton is Prosser Memorial Hospital in Prosser, about 13 miles away (a critical access hospital: a small rural hospital with 25 or fewer inpatient beds). The highest-rated hospital in that list is Kadlec Regional Medical Center, 4 of 5 stars on CMS's overall rating. Medigap has no hospital network: the Part A deductible ($1,736 in 2026) is covered the same here as anywhere.

4 Medicare-certified nursing homes are within 35 miles of Mabton. The highest-rated is Linden Post Acute in Toppenish (4 of 5 stars). Plans G and N pay the $217-a-day coinsurance for days 21 to 100 (2026).

Mabton is about 28 miles from Oregon. Your Washington Medigap policy pays the same at Oregon doctors and hospitals that accept Medicare, with no network. Oregon doesn't ban Part B excess charges, so if you use providers there, Plan G's excess-charge coverage can matter.
