TRICARE Out Of Network Lab Work: Costs & Coverage Guide

## Quick answer If you have lab work done at an out-of-network facility, you will almost always pay higher out-of-pocket costs, including a separate deductible and a 50% cost-share if you are on a Prime plan. For TRICARE Select users, you will pay a higher percentage of the "allowable charge" plus any amount the lab charges above that limit (known as balance billing).

## In detail TRICARE strongly encourages the use of network laboratories (such as LabCorp or Quest Diagnostics) or military hospital labs. Using an out-of-network lab—either by choice or because your doctor sent your sample to a non-partner facility—triggers different payment structures depending on your plan.

### TRICARE Prime Plans If you are enrolled in TRICARE Prime, Prime Remote, or US Family Health Plan, your primary care manager (PCM) is responsible for referring you to a network lab. If you bypass this and use an out-of-network provider without an authorization, you fall under the **Point-of-Service (POS) option**. * **Deductible:** You must pay a $300 individual or $600 family deductible (2026 rates) before TRICARE pays anything. * **Cost-Share:** Once the deductible is met, you pay 50% of the TRICARE allowable charge. * **Note:** The POS option does not apply to Active Duty Service Members (ADSMs), who must have an authorization for all non-military care.

### TRICARE Select Plans Select plans offer more flexibility to choose your own providers, but costs are tiered based on network status. * **Network Labs:** You pay a fixed copayment or a small percentage (e.g., 15-20% depending on your Group status). * **Out-of-Network Labs:** You pay a higher percentage of the allowable charge (typically 20-25%). Crucially, non-network labs can **balance bill** you up to an additional 15% above the TRICARE allowable rate.

### How it Happens (The "Hidden" Out-of-Network Bill) The most common way beneficiaries get hit with these bills is when they visit a **network doctor** who then sends their blood or tissue samples to an **out-of-network lab**. 1. Your doctor’s office is in-network. 2. The doctor takes the sample in their office. 3. The doctor sends the sample to a lab they prefer (which may be out-of-network). 4. TRICARE processes the claim as out-of-network because the *lab*, not the doctor, is the billing entity.

## Who this applies to * **TRICARE Prime Enrollees:** Affected by the Point-of-Service (POS) 50% cost-share if authorizations are not obtained. * **TRICARE Select Enrollees:** Affected by higher cost-shares and potential balance billing from non-participating labs. * **TRICARE For Life (TFL) Users:** Generally, if Medicare is primary, they follow Medicare's lab rules. However, if care is received overseas or Medicare doesn't cover the specific lab test, TRICARE out-of-network rules apply. * **Active Duty Service Members:** Always require a referral; they should never use out-of-network labs unless specifically authorized by the Defense Health Agency (DHA), or they may face 100% of the bill.

Common scenarios

### Scenario 1: The "Preferred" Lab Jane is on TRICARE Prime. Her network doctor draws blood and sends it to a specialty lab that is out-of-network because the doctor "prefers their reporting style." Because there was no authorization for out-of-network care, Jane receives a bill for $150 (50% of the $300 allowable charge) plus she has to meet her $300 POS deductible first.

### Scenario 2: The Select Choice Mark is on TRICARE Select and goes to an out-of-network lab for a $200 test. TRICARE’s allowable charge is $100. TRICARE pays 75% of that $100 ($75). Mark pays the remaining $25 plus the $100 difference between the lab’s price and TRICARE’s price. Total cost to Mark: $125.
