Medicare Broker in Somerset County, New Jersey

What Medigap actually costs in Somerset County right now

These are statewide filed rates for a 65-year-old non-smoking woman, verified against carrier rate filings as of 2026-07-12. A July 2026 probe of one ZIP in all 21 New Jersey counties — including Somerset — returned identical Plan G and Plan N filed-rate ranges statewide, so this table applies just as directly here as anywhere else in New Jersey. The spread between the cheapest and most expensive carrier for identical benefits is why comparing before you enroll matters.

Every carrier in that range is selling the identical, federally standardized benefits — the spread is pure pricing, not geography. Your exact rate depends on age and household discount eligibility. See the full NJ Medigap Rate Index for the complete dataset.

Medicare Advantage networks in Somerset County

If you're weighing Medicare Advantage instead of Medigap, the network question depends heavily on where in the county you live, because Somerset County sits at the edge of three separate hospital-referral areas:

• Robert Wood Johnson University Hospital Somerset — the county's only acute-care hospital, located in Somerville. It's a 339-bed facility and part of RWJBarnabas Health, New Jersey's largest academic health system, with a cardiology program and a dedicated cancer center (Steeplechase Cancer Center) serving central New Jersey.
• Overlook Medical Center — based in Summit (Union County) and part of Atlantic Health System, it's a common network choice for residents of Basking Ridge, Bernardsville, and Warren Township in southeastern Somerset County.
• Saint Peter's University Hospital and RWJUH New Brunswick — both in Middlesex County, and frequently in-network for Franklin Township residents given the township's border with New Brunswick.

Medicare Advantage plans build their networks around some combination of these systems, and coverage isn't uniform across the county — a plan built around RWJBarnabas may treat an Atlantic Health specialist as out-of-network, and vice versa. That makes Somerset County one of the places where checking your actual doctors against a plan's directory matters more than the brand name on the card.

If a plan makes a significant mid-year change to its provider network, Medicare can grant affected members a Special Enrollment Period to switch plans — you're not automatically stuck until the next Annual Enrollment Period.

A senior population that's still growing

Somerset County has a substantial senior housing and services network, including county-run Senior Wellness Centers such as the one at Basking Ridge, along with independent and assisted living communities like Fellowship Village and Sunrise of Basking Ridge. The county's Division on Aging & Disability Services also maintains a senior housing map covering adult retirement communities, assisted living, and income-restricted senior housing across the county.

With roughly 64,500 residents already 65 or older — about 18% of the county's population as of 2024 Census Bureau estimates — and more residents aging into Medicare each year, the choice between Medigap and Medicare Advantage, and between carriers within each, has real financial stakes. Timing matters most for Medigap: your six-month Open Enrollment Period begins once you're 65 or older and enrolled in Part B, and during it carriers must accept you regardless of health history. New Jersey adds a consumer protection on top — carriers cannot charge tobacco users a higher rate during that window. You can apply up to six months before your Part B effective date, which locks in your rate and guarantees no coverage gap.
