Medicare Supplement Plan G in California

Medicare Supplement Plan G in California

A Medicare Supplement Plan G in California is the most complete Medigap plan a person who is new to Medicare can buy. Plan G pays almost every cost Original Medicare leaves behind: the hospital deductible, the 20 percent coinsurance, skilled nursing coinsurance, and Part B excess charges. The one cost it does not pay is the annual Part B deductible, $283 in 2026.

Plan G benefits are federally standardized, so a Medigap Plan G from one insurance company covers exactly the same things as a Plan G from another. What changes from company to company is the price, and in California those prices vary a lot for identical coverage. That is why comparing Medigap Plan G cost in California, carrier by carrier, matters more than comparing benefits.

Who Plan G fits

A good fit if

  • You want the most predictable costs available with Original Medicare.
  • You see doctors often, or you are managing ongoing conditions and do not want a bill at every visit.
  • You want to use any doctor or hospital in the country that accepts Medicare patients, with no network and no referrals.
  • You travel, or split time between homes, and want the same coverage everywhere.

Think twice if

  • The monthly premium strains your budget. Plan N or High Deductible Plan G may fit better.
  • You rarely use care and would rather pay less each month and accept a deductible first. Look at High Deductible Plan G.
  • You want dental, vision, hearing, and fitness benefits bundled in one plan. Medigap plans do not bundle those; Medicare Advantage plans often do.

Questions about Plan G in California

What does Medicare Supplement Plan G cover in California?

Plan G covers the Part A hospital deductible, Part A and Part B coinsurance, the first 3 pints of blood, hospice coinsurance, skilled nursing facility coinsurance, Part B excess charges, and 80 percent of foreign travel emergency costs, up to plan limits. The only standard Medicare cost it does not cover is the annual Part B deductible, $283 in 2026.

How much is Plan G in California?

It depends on the carrier, your age, and your ZIP code, because the coverage is identical and only the price differs. Across 8 California ZIPs checked in the California Department of Insurance 2026 Medicare Supplement Rate Guide, Plan G annual premiums at age 65 ranged from $1,946 to $4,517 for an individual, non-tobacco policy (about $162 to $376 per month, 19 companies in every ZIP table checked). Guide survey rates, not quotes. The pricing section below shows the statewide range, and we can quote your exact age and ZIP at no cost.

Is Plan G the same as Medicare Part G?

No. There is no Medicare Part G. Medicare has Parts A, B, C, and D. Plan G is a Medigap plan letter, a private Medicare Supplement policy that works alongside Original Medicare (Parts A and B). The letters for Medigap plans and the letters for Medicare parts are two different systems that happen to share an alphabet.

Can I keep my doctor with Plan G?

Yes, if your doctor accepts Original Medicare patients. Medigap has no provider network, so you can see any doctor or hospital in the United States that accepts Medicare, and you do not need referrals. That freedom to choose any provider who accepts Original Medicare patients is the main reason people pick Medigap.

Does Plan G include prescription drug coverage?

No. No Medigap plan sold today includes drug coverage. Most people on Plan G buy a standalone Part D plan for prescriptions, and going without creditable drug coverage can lead to a late enrollment penalty, so the Part D choice matters even when the medical choice is settled.
