Plan G covers several costs that Original Medicare does not pay for on its own. When you receive care covered by Medicare Part A (hospital insurance), Plan G may cover your Part A deductible, which was $1,556 in 2024. It also covers coinsurance for hospital stays that extend beyond 60 days, up to an additional 365 days of hospital care that Medicare covers.

For Part B services (medical insurance like doctor visits and outpatient care), Plan G covers the Part B deductible, which was $240 in 2024. The plan also pays for Part B coinsurance or copayment amounts after you meet your deductible. This means if Medicare covers a service and you owe a percentage of the cost, Plan G may pay that portion.

Plan G also covers blood transfusions. Specifically, it pays for the first three pints of blood that Medicare does not cover under Part A or Part B. Additionally, this plan includes coverage for skilled nursing facility coinsurance. If you need care in a skilled nursing facility, Medicare covers up to 100 days, but you may owe coinsurance for days 21-100. Plan G covers these costs.

One important detail: as of 2020, Plan G does not cover the Part B excess charges in most states. Excess charges occur when a doctor charges more than the amount Medicare allows. In rare cases, some doctors may bill patients for this difference, and Plan G would not cover it in most regions.

Practical Takeaway: Plan G is designed to reduce predictable out-of-pocket costs by covering Medicare's deductibles and coinsurance. Reviewing what Plan G covers compared to your current healthcare costs can help you understand potential differences in your out-of-pocket spending.

Monthly Premium Costs for Plan G

The monthly cost of AARP Medicare Supplement Plan G varies significantly based on where you live, your age, and the insurance company's pricing structure. As of 2024, AARP Plan G premiums through UnitedHealthcare typically range from approximately $115 to $200 per month for newly eligible people, though these figures vary by state and rating method.

Insurance companies use different rating methods to set premiums. The most common method is "attained age" pricing, where your premium increases as you get older. When you first enroll in Plan G, your rate is set based on your age at that time. Your premium then increases each year as you age. Another method is "issue age" pricing, where your premium is based on your age when you enroll, and it generally increases more slowly over time. Some insurers use "community" rating, which means everyone in your area pays the same premium regardless of age.

Your location dramatically affects pricing. For example, someone in a rural area might pay $130 per month, while someone in a major metropolitan area might pay $175 per month for the same coverage. State regulations and the local healthcare market influence these differences.

AARP typically adjusts premiums annually. These adjustments reflect inflation, medical cost trends, and claims experience. In recent years, many insurers, including UnitedHealthcare for AARP plans, have increased premiums. From 2023 to 2024, some AARP Plan G premiums increased between 8% and 10% in various states.

When comparing Plan G costs to other supplement plans, Plan G has mid-range premiums. Plans with fewer benefits, like Plan N, often have lower premiums. Plans with more coverage, like Plan F (available only to people who were eligible for Medicare before January 1, 2020), typically have higher premiums. Understanding premium trends in your state helps you make informed decisions about long-term costs.

Practical Takeaway: Contact local insurance agents or AARP directly for current premium rates in your area. Premiums vary widely by location and age, so comparing specific quotes from your region provides more accurate information than national averages.

Annual Deductibles and Out-of-Pocket Limits

AARP Medicare Supplement Plan G has no annual deductible or out-of-pocket maximum. This is an important distinction from health maintenance organization (HMO) plans or preferred provider organization (PPO) plans, which typically include these limits. Under Plan G, once you pay your monthly premium, there is no separate yearly deductible you must reach before coverage begins, and there is no cap on how much the plan will pay toward covered services in a year.

However, you remain responsible for certain costs that Plan G does not cover. These include Medicare Part B excess charges in most states, costs for services Medicare does not cover at all, and any charges above what Medicare allows. You also continue to pay your monthly Medicare Part B premium (which was $164.90 per month in 2024 for most people) and your Medicare Part A premium if applicable.

Because Plan G covers Medicare's deductibles and most coinsurance, your primary out-of-pocket costs are limited to your monthly Plan G premium and any services that Medicare itself does not cover. If you receive substantial medical care, this structure can result in lower total out-of-pocket spending compared to Original Medicare alone, where you would owe both the Part A deductible ($1,556 in 2024) and Part B deductible ($240 in 2024), plus ongoing coinsurance percentages.

Consider a practical example: If you have a hospital stay lasting 10 days, Medicare Part A covers most costs, but you would owe the Part A deductible under Original Medicare. With Plan G, this deductible is covered. If you also see several specialists for outpatient care, you would typically owe 20% coinsurance under Original Medicare after meeting your Part B deductible. Plan G covers this coinsurance.

The lack of an out-of-pocket maximum means you have predictability in your healthcare costs. Your total annual healthcare expenses consist mainly of your monthly premium and any non-covered services. This differs from some other plan types where you face surprise costs once you exceed certain thresholds.

Practical Takeaway: Unlike many health plans, Plan G offers predictable costs with no annual deductible or out-of-pocket cap. Track your monthly premium and any non-covered services to estimate your total annual healthcare spending.

How Plan G Compares to Original Medicare Costs

Comparing AARP Medicare Supplement Plan G to Original Medicare helps illustrate the financial trade-offs between the two options. Original Medicare (Part A and Part B) requires you to pay several out-of-pocket costs when you receive care. Plan G reduces these costs but requires a monthly premium in addition to your Medicare Part B premium.

Under Original Medicare in 2024, you pay a Part A deductible of $1,556 per hospital stay, a Part B deductible of $240 per year, and then 20% coinsurance for most services after the deductible is met. For hospital stays beyond 60 days, you owe coinsurance amounts of $389 per day for days 61-90 and $778 per day for days 91-150. With Plan G, these costs are covered by the supplement plan after you pay your monthly premium.

Consider two scenarios for a person with moderate healthcare needs. Without Plan G, they might incur: one hospital stay costing $5,000 (patient owes $1,556 deductible plus 20% coinsurance on the remainder), four specialist visits costing $200 each (patient owes 20% after Part B deductible), and routine blood work costing $500 (patient owes 20%). Total out-of-pocket under Original Medicare alone could exceed $2,500 in one year.

With Plan G at a monthly premium of $150, the annual premium cost is $1,800. The same medical events would result in only the premium being paid, with Plan G covering the deductibles and coinsurance. The break-even point occurs around $700 in annual medical costs, meaning if you expect significant healthcare needs, Plan G typically results in lower total costs.

However, if your healthcare needs are minimal and you rarely
