Insurance complaints & medical review

Find CDI or DMHC help with an insurance or health plan complaint, denied care, billing problems and eligible independent medical reviews.

Before you start

  • Check which regulator oversees your actual policy or health plan. A company name alone does not establish jurisdiction.
  • Keep the insurer’s decision, your grievance record and supporting documents. IMR has specific eligibility and filing deadlines.
  • If there is an immediate serious threat to your health, contact the regulator for urgent assistance; ordinary grievance waiting rules have exceptions. County maps help you browse and do not determine plan eligibility.
