Washington National at a glance
Washington National Insurance Company has Washington-approved Medicare Supplement premiums for Plan A, Plan G, High-deductible Plan G, Plan N, and Plan F. Its Plan G costs $274 a month, 5th lowest of 17 insurers. That is $41 a month ($492 a year) more than the lowest Plan G we track, for the same standardized benefits. Its Plan N is $82 a month less than its own Plan G; whether that saving beats Plan N's office and ER copays depends on how often you see the doctor (see Plan G vs Plan N). It also offers high-deductible Plan G at $68 a month. You pay the first $2,950 of Medicare-covered costs in 2026 before it pays. The OIC chart shows it can apply a pre-existing condition waiting period. Washington caps that wait at three months, and it doesn't apply when you replace Medigap or other coverage you've had for at least three months. It can ask health questions when you apply outside a protected period such as your Medigap open enrollment. Washington's switching rule still lets anyone with Plan B through N move to its Plan B through N with no health questions.

Will Washington National raise my premium as I get older?
Not because of age. Washington's community rating rule means it charges every 65+ policyholder the same premium for a plan. It can still raise premiums for all policyholders after a rate increase is approved by the state.
