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 from 8:30 a.m. to noon and from 1 p.m. to 4:45 p.m., Monday through Friday. (The West Michigan call center is open from 8:30 a.m. to 4:45 p.m.)


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.
