What Is Reimbursement
Reimbursement is payment from your insurance company to your provider or directly to you for healthcare services already delivered. The amount depends on your plan's allowed charges, your deductible status, and whether the service meets your insurer's definition of medical necessity.
How Reimbursement Actually Works
Your provider submits a claim to your insurer within 30 to 120 days of your visit (timelines vary by state). The insurer reviews the claim code, cross-references it against your coverage terms, and determines what portion they'll pay. You receive an Explanation of Benefits detailing what was covered, what was denied, and why. The insurer then pays your provider directly. If your claim is denied, reimbursement stops until you appeal successfully.
The key variable: many denials stem from lack of prior authorization. Your insurer may have required pre-approval before the service occurred. Without it, they won't reimburse even if the service was medically necessary. This is one of the most common reasons claims get denied.
Reimbursement and Denials
When your claim is denied, reimbursement doesn't happen automatically on appeal. You have two paths:
- Internal appeal: Request your insurer reconsider. Most states require insurers to respond within 30 days for standard appeals, 72 hours for urgent cases. You can submit additional medical records or a physician's letter supporting medical necessity.
- External appeal: If internal appeal fails, state insurance regulators can force an independent review. This takes longer (30 to 60 days typically) but removes your insurer from the decision-making process. You have the right to request this in all 50 states under the Affordable Care Act.
State Regulations and Timelines
Reimbursement rules vary by state. Some states mandate 30-day payment windows after claim submission. Others allow 45 days. New York, for example, requires payment within 45 days of receipt or the claim is considered approved as submitted. Check your state's insurance commissioner website for exact timelines, as missing deadlines can strengthen your appeal if your insurer delays.
Common Questions
- If my claim is denied, do I owe my provider? That depends on your plan and state law. If you were an in-network provider and the denial was the insurer's error, many states require the insurer to pay, not you. Out-of-network providers are trickier. Don't assume you owe anything until you understand the denial reason.
- Can I request reimbursement in writing instead of calling? Yes. Send your internal appeal request via certified mail to your insurer's appeals department. Keep copies. This creates a paper trail courts and regulators respect more than phone calls.
- What if my provider goes out of network after treatment? You're typically still covered at in-network rates if you received the service while they were in-network. Reimbursement should reflect the contracted rate, not the provider's out-of-network fee.
