How to file an external review in Maryland
In Maryland, external review is administered directly by the Maryland Insurance Administration (MIA), which is unusual: rather than only assigning an outside Independent Review Organization, the MIA itself reviews most medical-necessity, cosmetic, and experimental or investigational denials and issues a binding written determination. You must first exhaust your plan's internal grievance process, then submit a written external review request, with any new records, to the MIA's Appeals and Grievance Unit within four months (120 days) of the final denial. Standard reviews generally conclude within about 60 days; emergency or expedited reviews are decided much faster, within roughly four business days for urgent cases. There is no charge to you, and the Attorney General's Health Education and Advocacy Unit can help for free.
Maryland appeal questions
How do I file an external review in Maryland after my health insurance claim is denied?
First complete your health plan's internal grievance process, then send a written external review request to the Maryland Insurance Administration's Appeals and Grievance Unit in Baltimore. Include your denial letter and any new medical records or documentation you did not submit before. Unlike many states, the MIA itself reviews the case and issues a final written determination, and it can direct your insurer to cover or pay for the service.
What is the deadline to request external review in Maryland?
You must submit your external review request to the Maryland Insurance Administration within four months, which is 120 days, after your health plan's final grievance decision. Missing that window can forfeit your right to review, so act promptly once you receive the final denial. If your situation is urgent, you can request an expedited review without waiting out the full internal process.
Does external review in Maryland cost anything, and how fast is an urgent case decided?
The external review process through the Maryland Insurance Administration is free to you, and the Attorney General's Health Education and Advocacy Unit offers free assistance as well. Standard reviews generally finish within about 60 days. For urgent situations, where delay could seriously threaten your health, an expedited decision is reached much faster, generally within about four business days.
Is the Maryland external review decision binding, and does it cover self-funded employer plans?
Yes. When the Maryland Insurance Administration overturns a denial, the decision is binding and the insurer must provide the coverage or payment. The MIA weighs whether the service is medically necessary and covered under your plan. Note that self-funded employer (ERISA) plans are generally regulated federally rather than by Maryland, so those members usually follow the federal external review path instead, and we can confirm which applies to your plan.
