Crown Heights: D-SNPs, IB-Dual, and the “default enrollment” letter

Crown Heights runs from the brownstones near Franklin Avenue to the large prewar apartment buildings along Eastern Parkway and the attached houses out toward Utica Avenue. Long-time Caribbean-American residents, the Lubavitch community around Kingston Avenue, and newer arrivals all get the same kind of letter from a Medicaid managed care plan about being placed in that plan’s Medicare D-SNP.

This page is for the person holding that letter, for residents who already have both Medicare and Medicaid and want IB-Dual and MAP explained, and for the daughters, sons, and home attendants who help. It describes what the letter asks, what each choice does, and where free counseling is. It does not enroll anyone.

Crown Heights is in Kings County and its Medicaid is administered by the NYC Human Resources Administration (HRA). The neighborhood spans more ZIP codes than most: 11213 and 11233 on the east, 11216 and 11238 toward Bedford-Stuyvesant and Prospect Heights, and 11225 on the south side near Prospect-Lefferts Gardens (all approximate; verify with USPS). None of those lines changes plan coverage; every New York City integrated plan on the state’s 2026 IB-Dual chart includes Kings County.

Hospitals ring the neighborhood rather than sit in the middle of it: Interfaith Medical Center on Atlantic Avenue to the north, Kingsbrook Jewish Medical Center on Rutland Road to the southeast, and NYC Health + Hospitals / Kings County on Clarkson Avenue just beyond. Which of them, and which of the clinics on Nostrand and Utica Avenues, are in a specific D-SNP’s Medicare network is the question to settle before the effective date.

The 3 train along Eastern Parkway (Kingston, Nostrand, and Utica Avenues), the 4 express, and the 2, 5, and shuttle at Franklin Avenue put the downtown Brooklyn HIICAP sites a few stops away.

Crown Heights mailboxes on Nostrand and Utica Avenues fill with plan marketing, and the default enrollment notice can be mistaken for it, or for a scam, because it comes from a company rather than from Medicare or HRA. It is a real notice. Your Medicaid plan sends it at least 60 days before Medicare begins, and it states the date the D-SNP would start and how to opt out, generally up to the day before (confirm on your letter). If nothing came, your plan may not do default enrollment.

If a relative in one of the Eastern Parkway buildings already gets many hours of Medicaid home care, look for the long-term-services version of the notice, which points to a Medicaid Advantage Plus plan rather than IB-Dual. The NY Medicaid Choice long-term care line, 1-888-401-6582, explains that path. Opting out of either generally means Medicaid continues as fee-for-service.
