Medigap premiums can increase dramatically over time, catching Medicare beneficiaries off guard with unexpected costs. Some policies see annual increases of 8-15%, while others remain more stable.
Comparing Medigap insurance companies by rate increases requires understanding different pricing methods and historical patterns. We at Dave Silver Insurance help you navigate these complex rate structures to make informed decisions about your supplemental coverage.
How Do Medigap Rate Structures Work?
Insurance companies use three distinct methods that directly impact your premium increases over time. Community-rated policies charge the same premium to everyone in your area regardless of age, which makes them the most predictable option for long-term budgets. These plans typically see annual increases of 3-5% based solely on healthcare inflation and claims experience. Issue-age rated policies lock in your premium based on your age when you first enroll, which protects you from age-related increases while still allowing for inflation adjustments of 2-4% annually.

Attained-Age Policies Create the Biggest Rate Shocks
Attained-age rated policies start with the lowest premiums but increase both from age and inflation, which creates double-digit annual increases for many beneficiaries. A 65-year-old might pay $150 monthly initially, but that same policy could cost $280 by age 75. Companies like Mutual of Omaha often use this structure with attractive introductory rates that become expensive over time. The National Association of Insurance Commissioners data shows attained-age policies provide valuable statistical data across various insurance lines including health coverage.
State Regulations Determine Available Options
Not all states offer every method, which limits your choices based on location. States like New York mandate community rating (which provides stable increases), while others allow all three structures. Each state’s insurance department maintains different approval processes that affect how quickly companies can implement rate increases.
Financial Stability Affects Rate Predictability
Companies with stronger financial ratings tend to implement more gradual rate increases over time. A.M. Best ratings of A+ or higher typically indicate insurers with better claims-paying ability and more conservative rate adjustment practices. Weaker companies may implement larger, less predictable increases to maintain profitability, which makes financial strength a key factor in your comparison process. Medigap insurance costs depend on various factors including the insurer’s financial stability and rating methodology.
What Actually Drives Your Medigap Premium Increases
Healthcare cost inflation remains the primary driver of Medigap premium increases, with health spending increasing by 7.5% from 2022 to 2023 according to the Centers for Medicare and Medicaid Services. Insurance companies pass these costs directly to policyholders through premium adjustments, which explains why even stable community-rated plans see consistent yearly increases. Claims experience within your specific plan pool significantly impacts your rates – when Plan G policyholders in your area file more expensive claims, everyone in that pool faces higher premiums the next year.
Insurance Company Loss Ratios Determine Rate Adjustment Frequency
Insurance companies must maintain loss ratios between 65-85% to remain profitable, which means 65-85 cents of every premium dollar goes toward claim payments. When loss ratios exceed these thresholds, companies request state approval for premium increases to restore profitability. AARP UnitedHealthcare typically maintains loss ratios around 75%, which results in more predictable annual increases of 3-5%. Companies with poor practices or aggressive initial prices often experience loss ratios above 90%, which leads to dramatic rate corrections that shock policyholders with increases of 15-25%.
State Approval Processes Create Different Rate Patterns
State insurance departments review and approve all Medigap rate increase requests, but approval standards vary dramatically between states. California requires extensive justification for increases above 10%, while states like Florida approve most reasonable requests without extensive review. Some states like New York prohibit age-based increases entirely, while others allow companies to implement both inflation and age-related adjustments simultaneously. These regulatory differences explain why identical Medigap plans from the same company can have completely different rate increase patterns based on your location.
Medical Trend Factors Beyond Basic Inflation
Prescription drug costs, new medical technologies, and specialist care expenses drive additional premium pressure beyond standard healthcare inflation. Medicare beneficiaries use more expensive treatments each year (including advanced cancer therapies and cardiac procedures), which increases claim costs for Medigap insurers. Companies must factor these trends into their rate projections, often resulting in increases that exceed general inflation rates.

Understanding these rate drivers helps you evaluate which companies manage costs most effectively, but you also need concrete strategies to compare actual rate increase patterns across different insurers.
How Can You Compare Rate Increases Between Companies
Call insurance companies directly and request premium history data for the past five years, focusing on specific plans like Plan G or Plan N in your state. Companies must provide this information through their customer service lines, and most maintain online rate history databases that show year-over-year percentage increases. Different carriers show varying increase patterns, with some implementing gradual adjustments while others may have more significant changes after initial years. Research individual company histories to understand their specific rate adjustment practices and timing.
Review A.M. Best Ratings and Financial Strength
A.M. Best financial strength ratings directly correlate with rate stability – companies rated A+ or higher implement more gradual increases than those with B+ or lower ratings. Companies with stronger ratings possess better claims-paying ability and more conservative rate adjustment practices. Weaker companies may implement larger, less predictable increases to maintain profitability, which creates significant cost variations over time.
Access State Insurance Department Records
Visit your state insurance department website to review actual rate documents, which show requested versus approved increases and company justifications for rate changes. State insurance departments maintain detailed online databases where you can compare requested increases versus approved amounts across different carriers. Companies with frequent large rate requests indicate poor initial pricing that will cost you significantly over time.

Analyze Loss Ratio Patterns and Claims Data
Insurance companies file annual loss ratio reports with state regulators, which show the percentage of premiums paid out in claims versus administrative costs. Companies consistently maintain loss ratios between 70-80% demonstrate better rate management than those with ratios above 85% or below 65%. Major carriers typically maintain stable loss ratios with predictable rate patterns, while smaller regional carriers often show volatile ratios that lead to unpredictable premium spikes. These reports reveal which companies price accurately from the start versus those that use low introductory rates followed by dramatic corrections.
Compare Multi-Year Rate Trends
Examine rate increase patterns over multiple years rather than focus on single-year adjustments. Some companies implement small increases consistently (2-4% annually), while others alternate between years with no increases and years with large jumps (10-15%). Consistent moderate increases typically cost less over time than volatile rate patterns, even when the volatile pattern shows lower increases in some years. When evaluating these trends, consider comparing quotes from multiple providers to find the best value for your specific situation.
Final Thoughts
Comparing Medigap insurance companies by rate increases demands analysis of multiple data points beyond initial premiums. Community-rated plans offer the most predictable increases at 3-5% annually, while attained-age policies can double your costs over a decade. Companies with A+ financial ratings from A.M. Best typically implement more gradual adjustments than weaker insurers who may shock policyholders with 15-25% spikes.
You should consider a plan switch if your current insurer consistently increases rates above 8% annually or shows volatile patterns that alternate between no increases and large jumps. State insurance department records reveal which companies price accurately from the start versus those that use low introductory rates followed by dramatic corrections. Most Medicare beneficiaries save money when they evaluate their options annually (especially during their birthday month when some states allow guaranteed switches).
