Lake Success is a small incorporated village in Nassau County, bordered by New Hyde Park, Great Neck, and Manhasset. The community’s primary medical hub is Northwell Health — with North Shore University Hospital in Manhasset and Long Island Jewish Medical Center in neighboring New Hyde Park serving as the region’s leading tertiary care centers. In 2026, understanding how your Medicare plan covers Northwell facilities is more important than ever.
⚠️ 2026 Northwell Health Network Alert — Lake Success Residents
In 2026, Wellcare Medicare Advantage terminated its Northwell Health network contract, leaving Wellcare members without in-network access to North Shore University Hospital, Long Island Jewish Medical Center, and other Northwell facilities as of July 1, 2026. Fidelis Care was in active contract negotiations with Northwell as of mid-2026. If you are enrolled in a Medicare Advantage plan and see Northwell doctors, verify your network status now — or call Craig Smith at 917-740-1895 for a free review.
Northwell Health and Medicare in Lake Success
For Lake Success residents, Northwell Health is the dominant health system in the area. The two primary Northwell facilities serving Lake Success are:
| Hospital | Location | Key Services |

| Long Island Jewish Medical Center | 270-05 76th Avenue, New Hyde Park, NY 11040 | 827-bed teaching hospital, nationally ranked in 9 adult specialties and 10 pediatric specialties |
Whether your Medicare plan covers these facilities depends on which plan you’re enrolled in and whether that carrier has a current in-network contract with Northwell Health. Craig Smith verifies Northwell network status for every plan we recommend and monitors changes as they occur.

Medicare Advantage vs. Medigap in Lake Success
Medicare Advantage
Often $0 premium with drug, dental, vision, and hearing benefits. However, Northwell Health’s network participation with Medicare Advantage carriers has been volatile in 2026. Before enrolling, it’s essential to verify that your specific Northwell doctors and facilities are covered under the plan you’re considering.
Medicare Supplement (Medigap)
Higher monthly premium, but you can see any doctor who accepts Medicare — including all Northwell physicians — with no network restrictions and no referrals required. New York’s guaranteed issue rights mean you can enroll or switch year-round. Lake Success residents who want guaranteed access to North Shore University Hospital and LIJ, Medigap often provides the most reliable long-term coverage.
