Advisor's note:

Northwestern is in-network with most major Chicago Medicare Advantage plans. BCBS of Illinois and Humana have particularly broad Northwestern access.

Original Medicare with Medigap = full Northwestern access

If keeping Northwestern 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.

Northwestern accepts Medicare. So: Original Medicare + Medigap means you can see any Northwestern doctor, in any Northwestern 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 Northwestern doctor is in your Medicare Advantage plan

  1. 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?"
  2. Check the plan's online provider directory. Search by full name. Verify the address matches your Northwestern location.
  3. Call your Northwestern 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.
  4. If you have specialists, repeat for each one. Network status varies physician-by-physician within the same hospital system.
