Original Medicare with Medigap = full Mount Sinai access
If keeping Mount Sinai in-network is non-negotiable, the simplest path is Original Medicare (Parts A and B) plus a Medigap plan plus a standalone Part D plan. Medigap plans don't have networks — they pay out-of-pocket costs at any provider that accepts Medicare.
Mount Sinai accepts Medicare. So: Original Medicare + Medigap means you can see any Mount Sinai doctor, in any Mount Sinai hospital, with no referrals or pre-authorizations.
The trade-off: Medigap costs $100-$250/month (versus often $0 for Medicare Advantage), and standalone Part D adds $15-$70/month. But you get total provider freedom and predictable out-of-pocket costs.
How to verify your Mount Sinai doctor is in your Medicare Advantage plan
- Call the plan member services line with your doctor's full name and NPI number. Ask: "Is Dr. [Name], NPI [#####], in-network for [plan name] for 2027?"
- Check the plan's online provider directory. Search by full name. Verify the address matches your Mount Sinai location.
- Call your Mount Sinai doctor's office. Ask the receptionist which Medicare Advantage plans they accept. Verify both that the practice is in-network and that the specific physician is in-network — they're sometimes different.
- If you have specialists, repeat for each one. Network status varies physician-by-physician within the same hospital system.
