Medigap Rating Methods: Community-Rated vs Attained-Age vs Issue-Age

Understanding the Three Medigap Rating Methods

Medigap rating methods are the three pricing systems insurers use to calculate Medicare Supplement premiums: community-rated, attained-age, and issue-age. Each method determines how much you pay when you enroll and how those costs change over time.

Medigap insurers do not all price their policies the same way. State regulations determine which rating methods are available in your area, and each method produces a different premium trajectory over a policyholder's lifetime.¹

These three methods work differently, and the difference matters enormously over a 20- or 30-year policy horizon.

• Community-rated: All enrollees pay the same premium regardless of age or sex. Yearly adjustments may occur for reasons other than individual aging, such as overall medical inflation or claims experience across the entire pool.²
• Issue-age-rated: Premiums are set based on your age when you first buy the policy. They do not increase just because you get older, though insurers may raise rates for broader market factors.³
• Attained-age-rated: Premiums start lower than the other two methods but increase automatically as you age. By your 80s and 90s, these increases can be substantial.⁴

An insurance agent or Medicare counselor who cannot explain these three methods clearly risks recommending a policy that becomes unaffordable for a client five or ten years down the road.

What Medigap Rating Methods Mean for Your Wallet

The rating method directly determines how much a client pays at age 65 versus age 85. Consider a hypothetical scenario: a 65-year-old in good health shopping for Plan G in a state where all three methods are available.⁵

Under attained-age pricing, the initial premium might be $120 per month. Under issue-age, it might be $140. Under community-rated, it might be $150. The attained-age policy looks cheapest at enrollment.

But by age 80, that attained-age premium could reach $280 per month or more, while the issue-age policy might have risen only to $170 due to market-wide adjustments. The community-rated policy might sit at $195. The client who chose the lowest initial premium ends up paying significantly more in later years.

, making the long-term cost comparison even more critical for anyone enrolling now.⁶

How Community-Rated Policies Keep Premiums Stable Over Time

Community-rated Medigap plans charge identical premiums to all enrollees regardless of age or sex.² A 70-year-old and an 85-year-old in the same plan pay the same amount.

This method spreads risk across the entire pool of policyholders. Premiums may still rise each year, but those increases reflect the claims experience of the whole group, not the individual aging of any single member. The result is a flatter premium curve over time.

For a client who plans to keep a Medigap policy for 20 years or more, community-rated pricing often produces the lowest total lifetime cost. The trade-off is that the initial premium is typically higher than an attained-age policy.

Insurers using community rating must file rate changes with state regulators, and those changes apply uniformly to all policyholders. A client in a community-rated plan will not face a sudden premium spike on their birthday.

Why Attained-Age Pricing Gets More Expensive Each Year

Attained-age-rated Medigap premiums start lower but increase as you age, often substantially so by your 80s and 90s.⁴ The premium is recalculated each year based on the policyholder's current age.

For example, suppose a client buys an attained-age Plan N at age 65 for $110 per month. At age 66, the premium adjusts upward. At age 67, it adjusts again. By age 75, that same policy might cost around $200 per month. By age 85, it could exceed $350 per month in a typical scenario.

The initial savings are real, but they come with a predictable cost trajectory. An agent who recommends an attained-age policy to a 65-year-old client should show the projected premiums at age 75, 80, and 85 so the client understands the long-term commitment.

Some states restrict or prohibit attained-age rating because of the burden it places on older enrollees. In states where it is allowed, it remains the most common pricing method for Medigap policies sold today.

Issue-Age Policies: Locking In Rates Based on Enrollment Age

Issue-age-rated Medigap premiums are set based on your age when you first buy the policy and do not increase just because you get older.³ A 65-year-old who buys an issue-age policy pays the 65-year-old rate for the life of the policy.

The premium can still rise due to inflation, medical cost trends, or changes in the insurer's claims experience. But the age component of the rate is frozen at enrollment. A client who buys at 65 will never pay the 75-year-old rate, even when they turn 75.

This creates a strong incentive to enroll as early as possible. A 65-year-old who delays enrollment to age 70 will pay the 70-year-old rate for life, which is higher than the 65-year-old rate.

Issue-age pricing is common in states that restrict attained-age rating. It offers a middle ground between the stability of community rating and the low initial cost of attained-age pricing. For clients who enroll at 65 and keep the policy for decades, issue-age often provides the best balance of affordability and predictability.

Comparing the Three Rating Methods Side by Side

The table below summarizes how each method behaves across key dimensions.

A second table shows a hypothetical premium projection for a Plan G policyholder enrolling at age 65⁵.

These figures are illustrative. Actual premiums vary by insurer, state, and plan type. The pattern, however, is consistent across markets.

Which Medigap Rating Method Saves You the Most Money

The answer depends on the client's age at enrollment, expected longevity, and tolerance for future premium increases.

For a 65-year-old in excellent health who expects to live into their 90s, community-rated or issue-age pricing almost always produces the lowest total lifetime cost. The higher initial premium is offset by the absence of age-based increases in later decades.

For a 75-year-old enrolling for the first time, attained-age pricing may be the only option available, and the shorter expected policy duration reduces the impact of annual increases.

For a client on a fixed income who cannot absorb large premium jumps, community-rated or issue-age pricing provides the predictability needed for long-term budgeting.

Agents should run side-by-side projections for each client using actual rate filings from carriers in their state. The numbers tell the story better than any general rule.

How Your State Regulates Medigap Pricing and Availability

State regulations determine which rating methods Medigap insurers may offer, so availability varies significantly by location.¹ Some states allow all three methods. Others restrict or prohibit attained-age rating entirely.

For example, California, Florida, and Texas allow attained-age rating. New York and Connecticut require community rating for all Medigap plans. Massachusetts uses a modified community rating system.

An agent practicing in a state that allows all three methods has the most flexibility to match clients with the right pricing structure. An agent in a community-rating-only state must focus on comparing insurers' rate stability and financial strength rather than rating method.

Clients who move to a different state after enrolling in a Medigap plan may face different pricing rules if they switch plans. This is an important consideration for snowbirds and retirees who relocate frequently.

Your Next Step

Pull the current rate filings from three Medigap carriers in your state, one using each rating method. Build a side-by-side premium projection for a 65-year-old client at ages 65, 70, 75, 80, and 85. Present that table in your next client appointment and let the numbers drive the recommendation.
