New Jersey Medicare AdvisoryBy New Jersey Medicare Advisory • June 5, 2026
Here's something that surprises many New Jersey Medicare beneficiaries: You and your neighbor could both have Medigap Plan G with identical benefits, yet one of you might be paying significantly more each month. This isn't a mistake or unfair practice—it's how Medigap pricing actually works. Let's unpack why standardized plans don't mean standardized prices.
Congress standardized Medigap plans to make comparison shopping easier. A Plan G from one company covers exactly what Plan G covers from another company—no exceptions. The benefits are carved in stone. But here's what many people miss: while the federal government standardizes the benefits, insurance companies have considerable freedom to set their own premiums.
Each insurance carrier operates with different business models, overhead costs, claim experiences, and pricing strategies. Some companies specialize in Medicare products and operate with lean administrative structures. Others are large multi-line insurers with higher operational costs spread across their Medicare divisions. These structural differences directly impact what they charge for identical coverage.
Think of it like buying the same brand of cereal at different stores. The product inside the box is identical, but ShopRite, Wegmans, and a convenience store all charge different prices based on their own cost structures and business strategies.
Medigap carriers in New Jersey use one of three pricing methodologies, and your premiums will increase differently depending on which method your insurer uses:
Community-rated (or "no-age-rated") plans charge everyone the same premium regardless of age. A 65-year-old pays what an 85-year-old pays. These plans still increase over time due to inflation and healthcare costs, but not because you're getting older.
Issue-age-rated plans base your premium on your age when you first buy the policy. Your rate won't increase just because you have another birthday, though it will rise with inflation and other factors.
Attained-age-rated plans increase as you get older. Your premium at age 75 will be higher than at 65, even if nothing else changes. These often start with the lowest initial premiums but can become expensive over time.
The same company might appear affordable initially but become costly years later, while another company's higher starting premium might be the better long-term value. This is why shopping solely on today's price can be shortsighted.
Beyond pricing methods, several other factors create premium variations between carriers:
Claims experience matters tremendously. If a company's policyholders file more claims than expected, that insurer may raise premiums more aggressively than competitors with healthier risk pools.
Company efficiency plays a role too. Insurers with streamlined claims processing, lower marketing costs, and efficient customer service can often charge less while maintaining profitability.
Market strategy also influences pricing. Some companies intentionally price low to attract new customers, planning to raise rates later. Others maintain consistent, moderate pricing year after year. Some actively market to seniors while others barely advertise, keeping acquisition costs low.
New Jersey has dozens of carriers offering Medigap plans, and their premium differences can be substantial—sometimes hundreds of dollars monthly for absolutely identical coverage.
Understanding that premiums vary widely should motivate you to shop carefully. Don't assume your current plan offers the best value, and don't assume the most expensive option provides better coverage—it doesn't. With standardized plans, you're shopping for price and customer service, not benefits.
Most New Jersey residents have between 20-40 different Medigap options available to them. Working with someone who can compare multiple carriers simultaneously helps you see the full pricing landscape rather than just one company's offering.
Remember, during your Medigap Open Enrollment Period (the six months starting when you're 65 and enrolled in Medicare Part B), you have guaranteed issue rights. Companies can't charge you more or deny coverage based on health conditions. This is your golden opportunity to choose based on price rather than being locked into whatever company will accept you.
Identical coverage shouldn't mean identical costs. The difference between the highest and lowest premiums for the same standardized Medigap plan in New Jersey can be eye-opening. Before you renew your current policy or select your first Medigap plan, take time to compare what's actually available to you.
