A provider saying it “accepts Medicare” does not automatically mean it participates in every Medicare Advantage network. Original Medicare acceptance, a Medicare Advantage contract, and a specific doctor's participation are three different questions.
What current local sources say
| Provider | What is confirmed | What you still need to verify |
|---|---|---|
| St. Charles Health System | Its current insurance page lists Medicare and warns that contracts can change. A separate agreement confirms PacificSource Medicare Advantage participation for 2026. | Your exact plan, facility, and individual clinician. The PacificSource Medicare Advantage agreement described by St. Charles was for one year. |
| Summit Health Oregon | Summit states that it accepts Medicare, Medicare Advantage, and all Medicare Supplement plans. | Your exact Medicare Advantage product and the individual clinic or clinician you intend to use. |

A four-part network check
Check 1
Your exact plan
Carrier names are not enough. Confirm the full plan name and contract/product shown on your member card or enrollment materials.
Check 2
Each clinician
A hospital system, medical group, facility, and individual specialist can have different contracting status.
Check 3
Your county and year
Medicare Advantage availability is county-specific, and contracts can change for January 1.
Check 4
Both directories
Check the plan's directory and the provider's billing office. Save the date, representative name, and confirmation number.
Why older announcements need context
St. Charles announced network changes involving Humana, Health Net, and Wellcare beginning in 2024. That announcement is useful history, but it is not enough by itself to establish a provider's status for a later plan year. Treat dated announcements as a prompt to recheck the current directory.
Original Medicare and Medigap
With Original Medicare, the key question is whether the provider accepts Medicare. A Medicare Supplement policy generally does not create its own provider network; it helps pay eligible costs after Original Medicare. That is different from Medicare Advantage, where the plan's network rules matter. See our Bend comparison of Medicare Advantage and Medicare Supplement.
