Yes. Because Medicare is a federal program that does not recognize domestic partners as Internal Revenue Service-eligible dependents, Medicare becomes primary for your domestic partner at age 65 even though you are still working and they are enrolled in NYSHIP as a dependent. Regardless of your employment status, your domestic partner must have Medicare Parts A and B in place when first eligible due to age for Medicare. Please note that your domestic partner would retain NYSHIP as secondary coverage and they would be eligible for Medicare Part B reimbursement from the NYS Department of Civil Service. Please call (1-800-833-4344) for further details.
