What Is Allowed Amount
The allowed amount is the maximum dollar figure your insurance company will reimburse for a specific medical service or procedure. This is the negotiated rate between your insurer and the healthcare provider, not necessarily what the provider charges or what you might owe out of pocket.
For example, if a dermatologist bills $500 for a skin biopsy but your insurer's allowed amount is $275, the insurer will base its payment on $275. The provider can bill you for the remaining $225 only if they're out-of-network and you agreed to balance billing upfront. In-network providers must write off the difference.
How Allowed Amount Affects Denials and Appeals
The allowed amount appears on your Explanation of Benefits (EOB) and is critical when evaluating whether a claim denial is legitimate. Some insurers deny claims by stating the service exceeds the allowed amount, which is actually a coverage decision, not a processing error. This distinction matters for appeals.
When you file an internal appeal, you should challenge whether the service truly exceeded the allowed amount or whether the denial was based on medical necessity instead. Many insurers conflate the two reasons. If your claim was denied due to medical necessity, the allowed amount becomes irrelevant. If it was denied as exceeding the allowed amount, request documentation showing how your insurer calculated that figure and what contracted rate applies to your specific plan.
Key Factors Affecting Allowed Amounts
- Plan type and tier: HMO plans typically have lower allowed amounts than PPO plans. Tiered networks (bronze, silver, gold) within ACA plans set different allowed amounts per provider.
- Geographic variation: Allowed amounts vary by zip code and region. A procedure in San Francisco may have a $1,200 allowed amount while the same procedure in rural Montana carries $650.
- Network status: In-network providers accept negotiated allowed amounts. Out-of-network providers are not bound by these rates and can balance bill you for the full difference.
- Prior authorization requirements: Some insurers condition higher allowed amounts on prior authorization approval. If you didn't obtain authorization first, they may reduce the allowed amount retroactively.
- State regulations: State insurance commissioners can challenge unreasonably low allowed amounts, particularly for emergency services. Most states require insurers to publish their allowed amounts upon request.
Common Questions
- Can an insurer change the allowed amount after I receive treatment? No. The allowed amount is locked in on the date of service based on your active plan and network status at that time. However, if your insurer retroactively determines prior authorization was required and you didn't obtain it, they may apply a lower allowed amount or deny the claim entirely. This is why requesting prior authorization details before any elective procedure is essential.
- Is the allowed amount the same as what I owe? Not necessarily. You owe your portion of the allowed amount based on your deductible, copay, and coinsurance percentage. If the provider is out-of-network, you may owe the full difference between their charge and the allowed amount. Review your EOB to see the breakdown of what the insurer paid and what you owe.
- What do I do if the allowed amount seems too low? File an internal appeal requesting a review of the allowed amount determination. Include documentation of fair market value for that service in your geographic area. You can also file a complaint with your state insurance commissioner if you believe the allowed amount violates state insurance regulations on network adequacy or access to care.
