Should I contact the hospital before filing a formal complaint?

Usually, yes. It often helps to contact the hospital billing office first, because some problems are simple billing errors or misunderstandings that can be clarified before you escalate.

Can I file a complaint about a medical bill if it went to collections?

Yes. If the issue involves debt collection or credit reporting, the CFPB may be a more relevant complaint path than the hospital itself.

Where to Complain About a Hospital Bill

The right complaint path depends on the problem. Start with the provider billing office for unclear or incorrect charges, the insurer for claim-processing issues, the CFPB for debt collection or credit-reporting problems, and the CMS No Surprises complaint process when you think federal surprise-billing protections may apply.
