How Much Does Medigap Plan G Cost

The monthly cost of Plan G varies by insurance company, location, age, and pricing method. There is no single national premium that applies to everyone. People should also account for their regular Medicare Part B premium when estimating total healthcare expenses.

Factors that can influence the monthly premium include:

  • Location: Premiums differ between states and regions.

  • Age: Some insurers base prices on age, while others use different pricing methods.

  • Pricing structure: Premiums may be based on attained age, issue age, or community rating.

  • Discounts: Certain insurers offer discounts to eligible policyholders.

  • Annual increases: Premiums may rise over time because of age, inflation, or other pricing factors.

For 2026, the standard Medicare Part B premium is $202.90 per month, and the annual Part B deductible is $283. Plan G generally does not cover this Part B deductible, so beneficiaries pay it themselves before Plan G covers eligible Part B cost-sharing.

What Does Medigap Plan G Not Cover

Although Plan G covers many Medicare-related expenses, it does not pay for every healthcare service. Understanding exclusions can help people estimate expenses that may remain their responsibility.

Common exclusions include:

  • Routine dental care and most routine vision services.

  • Hearing aids and eyeglasses.

  • Long-term custodial care in a nursing home.

  • Prescription medications covered through a separate Medicare Part D plan.

  • The annual Medicare Part B deductible.

Coverage depends on Medicare eligibility rules, policy terms, and whether a service is covered by Original Medicare.

How Medigap Plan G Works With Original Medicare

Plan G supplements Original Medicare rather than replacing it. Medicare generally processes an eligible claim first, and the Medigap insurer then pays its share according to the policy's benefits. The beneficiary remains responsible for expenses that neither program covers.

Important points to understand include:

  • You generally need both Medicare Part A and Part B to purchase Medigap.

  • Plan G is designed to work with Original Medicare, not Medicare Advantage.

  • Each covered individual needs their own Medigap policy.

  • Prescription drug coverage generally requires a separate Part D plan.

Tips for Understanding Medigap Plan G Costs

Reviewing plan details carefully can help people understand the potential financial commitment before enrolling. Since standardized Plan G benefits are generally the same across insurers, comparing premiums and policy conditions can provide useful information.
