## Definition Balance billing is the practice where a non-network provider bills a patient for the difference between the provider's actual charge and the TRICARE-allowable amount.

## What it means in practice In the TRICARE system, balance billing occurs primarily when you see **Non-Network, Non-Participating providers**. These are healthcare professionals who do not have a contract with TRICARE and do not agree to accept the TRICARE-allowable charge as payment in full. Under federal law, these providers are permitted to charge up to 15% above the TRICARE-allowable amount. This "extra" 15% is the balance bill, and the beneficiary is responsible for paying it out of pocket in addition to their standard deductible and cost-share.

For example, if you see a non-participating specialist for a procedure that TRICARE determines should cost $100 (the allowable amount), but the doctor charges $115, TRICARE will pay its percentage of the $100. You are then responsible for your normal cost-share PLUS the additional $15. If the doctor were to charge $130, they would still legally be capped at billing you for a total of $115 ($100 allowable + 15% maximum) if they are a "covered" provider under TRICARE regulations.

You can avoid balance billing entirely by seeing **Network Providers** or **Participating Non-Network Providers**. Network providers (managed by Humana Military in the East and TriWest in the West) have signed contracts agreeing to accept TRICARE’s rates as full payment. Participating providers are those who do not have a permanent contract but agree to "accept assignment" on a case-by-case basis. In both scenarios, the provider is prohibited from billing you for any amount above the TRICARE-allowable charge and your specific 2026 cost-share.

It is important to note that TRICARE Prime enrollees usually avoid balance billing because they are required to see network providers. Balance billing is most common for TRICARE Select, TRICARE Reserve Select, and TRICARE For Life beneficiaries who choose to utilize the "Point of Service" option or see providers outside the established network.
