What Is Prospective Review
Prospective review is an insurer's evaluation of medical necessity before your healthcare provider delivers a service or procedure. It's the formal process your insurance company uses to decide whether they'll cover a treatment in advance. This is also called prior authorization. The insurer reviews your medical records, diagnosis, and the proposed treatment against their coverage guidelines and medical policy criteria to determine if it meets the threshold for medical necessity.
Why It Matters
Prospective review directly affects whether you'll face a denied claim after treatment. If your insurer denies coverage during prospective review, your provider may refuse to proceed, or you'll face an unexpected bill. About 16% of prior authorization requests are initially denied according to 2023 insurer data. When denials occur, you'll need to file an internal appeal within your state's timeframe, typically 30 to 90 days depending on your state's insurance regulations. Understanding how this process works helps you gather the right documentation early and build a stronger appeal case if needed.
How It Works
- Your provider submits: Before scheduling your procedure, your healthcare provider's office submits a prior authorization request to your insurance company. They include your medical records, the specific procedure code, diagnosis codes, and clinical justification for why you need it.
- Insurer reviews: The insurer's utilization management team compares the request against their medical necessity guidelines. These guidelines are based on clinical evidence, FDA approvals, and industry standards like those from the American Medical Association.
- Decision issued: The insurer sends an approval, conditional approval, or denial, typically within 3 to 5 business days for urgent requests and up to 30 days for standard reviews. This decision appears on your Explanation of Benefits (EOB) once treatment occurs.
- If denied: You can file an internal appeal challenging the denial. Most states require insurers to respond within 30 days for expedited appeals and 60 days for standard appeals.
Key Details
- Timing matters: Prospective review happens before treatment. If your provider proceeds without prior authorization approval, you may be liable for the full cost, even if you later win an appeal.
- State variations: Insurance regulations differ by state. Some states mandate faster response times or stricter medical necessity standards. Your state's insurance commissioner's office publishes these requirements.
- What triggers it: Most insurers require prospective review for surgeries, imaging (MRI, CT scans), specialty medications, mental health treatment, and certain diagnostic procedures. Routine office visits typically don't require it.
- Medical necessity criteria: Insurers evaluate whether the treatment is appropriate for your diagnosis, follows clinical guidelines, and is the most cost-effective option. They may deny a requested treatment if they consider a less expensive alternative medically appropriate.
- Appeal documentation: When appealing a prospective review denial, you'll need clinical evidence supporting medical necessity. Your provider's detailed clinical notes, peer-reviewed studies supporting the treatment, and specialist recommendations strengthen your internal appeal.
Common Questions
- Can I get treatment before receiving prospective review approval? Technically yes, but you risk paying out of pocket. If you proceed without approval and later win an internal appeal, the insurer may still only pay based on their approved amount, leaving you responsible for the gap.
- How long should prospective review take? Standard reviews take up to 30 days. Urgent cases (when delay would seriously harm your health) require responses within 72 hours in most states. Your provider's office should specify which timeframe applies to your request.
- What's the difference between prospective review and concurrent review? Prospective review happens before treatment. Concurrent review happens during treatment (like a hospital stay), where the insurer monitors ongoing medical necessity daily. Retrospective review happens after treatment, which often leads to claim denials on your EOB.
