New Jersey Medigap (Medicare Supplement) Plans
Medigap plans in New Jersey help cover out-of-pocket costs not paid by Original Medicare, including the Part A deductible, Part B coinsurance, and skilled nursing facility copays. Medigap plans are standardized by federal law, meaning Plan G from one carrier covers the same benefits as Plan G from another carrier. The difference is premium cost.
Plans available in New Jersey: A, B, C, D, F, G, K, L, M, N (plus High-Deductible F and High-Deductible G). Plans C and F are only available to those who became Medicare-eligible before January 1 2020.
Most popular plan: Plan G is the most popular plan among new enrollees (37% of new Medigap members in NJ choose Plan G). Plan F has the highest total enrollment (171779 policyholders) but is closed to new enrollees since 2020. Plan N is the third most popular with approximately 87811 enrollees. is the most popular Medigap plan in New Jersey. Plan G covers all gaps in Original Medicare except the annual Part B deductible ($240 in 2026). Plan N is the most popular lower-premium alternative, with small copays for some doctor visits and ER visits.
Pricing method: New Jersey uses community-rated Medigap pricing. This is the most favorable method for consumers because premiums are the same regardless of age. Your premium will not increase simply because you get older.
The average monthly Plan G premium for a 65-year-old in New Jersey is approximately $170. Plan N averages approximately $125 per month. Actual premiums vary by carrier, age, gender, tobacco use, and zip code. Always compare quotes from at least three carriers.
New Jersey Medigap Switching Rights
New Jersey does not have a Medigap birthday rule. Your primary opportunity to buy or switch Medigap plans without medical underwriting is during your initial Medigap Open Enrollment Period, which lasts 6 months starting when you first enroll in Medicare Part B at age 65 or older.
After your initial OEP closes, you may face medical underwriting if you apply for a new Medigap policy. However, federal law provides guaranteed issue rights in specific situations, such as losing employer coverage or leaving a Medicare Advantage plan during your first year.
New Jersey guaranteed issue protections: Beyond the federal 6-month Medigap OEP, New Jersey provides significant state-level GI protections: (1) Disabled beneficiaries ages 50-64 get a 6-month GI window from Part B enrollment to enroll in Medigap Plan D with any NJ insurer, with premiums capped at the lowest rate charged to 65+ enrollees. (2) Disabled beneficiaries under age 50 get GI access to Medigap Plan D through Horizon Blue Cross Blue Shield of NJ (state-contracted carrier), also with premiums capped at the 65+ rate. (3) NJ recognizes voluntary termination of MA coverage as a qualifying event for GI rights. (4) Standard 12-month trial right applies if you drop Medigap to try MA for the first time.
New Jersey Medicare Advantage (Part C)
Approximately Approximately 1750000 to 1800000 people in New Jersey are enrolled in Medicare. About Approximately 41-45 percent as of late 2024, below the national average of approximately 50 percent. Notably 32 percent of NJ MA enrollees are in group (employer-sponsored) plans, one of the highest shares in the country. of New Jersey Medicare beneficiaries choose Medicare Advantage plans, with the remainder on Original Medicare with or without Medigap supplement coverage.
Medicare Advantage plans in New Jersey are offered by private insurers as an alternative to Original Medicare. Most MA plans include prescription drug coverage (Part D) and often add dental, vision, and hearing benefits. However, MA plans use provider networks, which can limit your choice of doctors and hospitals.

- Networks matter: HMO plans require you to use in-network providers except in emergencies. PPO plans allow out-of-network care at higher cost.
- $0 premium plans: Many New Jersey MA plans have $0 monthly premiums (you still pay your Part B premium).
- Maximum Out-of-Pocket (MOOP): MA plans cap your annual spending, unlike Original Medicare which has no cap.
