Request an independent medical review

Request review of an eligible health coverage denial; check your plan’s regulator, grievance requirements, filing deadline and urgent-review rules.

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.
