Provider Inquiry — Facilities (BCBSM)

The Provider Inquiry Department is your primary resource for most unresolved issues. For questions about billing, benefits or eligibility that CAREN and web-DENIS can't answer, call Provider Inquiry Monday through Friday.


To save time, please have ready all records and documentation regarding your issue and the steps you've taken to resolve it when you make your call.
