# [TRICARE vs. TRICARE Supplement Insurance: Common Questions Answered | SelmanCo](https://blog.selmanco.com/blog/tricare-vs.-tricare-supplement-insurance-common-questions-answered-selmanco)

As a member of the military community, you’ve earned valuable health care benefits through TRICARE, the Department of Defense’s official health care program for active-duty service members, retirees, and eligible family members.

However, TRICARE doesn’t cover *every* out-of-pocket cost, and that’s where a [**TRICARE Supplement Insurance plan**](https://www.selmanco.com/tricare-supplement) can play an important role in your overall financial protection. This blog answers common questions to help you decide what’s right for you.

### **What is TRICARE?**

TRICARE is the U.S. military’s health care program that provides comprehensive medical benefits, including medical care, hospital care, and pharmacy services, to qualifying beneficiaries. Plans vary based on your status, for example TRICARE Prime, TRICARE Select, and others, but all operate under the Department of Defense with coverage rules, cost-shares, and eligibility defined by the Military Health System.

TRICARE is *primary insurance*, meaning it pays first under most circumstances when you receive care. Learn more about TRICARE plans and eligibility on the official [**TRICARE website**](https://www.tricare.mil/).

### **What is TRICARE Supplement Insurance?**

A **TRICARE Supplement Insurance plan** is secondary, voluntary insurance designed to work alongside your existing TRICARE coverage. It helps pay costs TRICARE doesn’t cover, such as co-pays, cost-shares, deductibles, prescription expenses, and excess charges, after TRICARE pays its portion.

According to SelmanCo, this plan “wraps around your TRICARE health insurance coverage” so you can reduce or even eliminate many out-of-pocket costs. You can read more about how this works on [**SelmanCo’s TRICARE Supplement page**](https://www.selmanco.com/tricare-supplement).

### **How Do They Work Together?**

Here’s the basic sequence when you use both plans:

### **Who Can Use Each?**

### **What Does a TRICARE Supplement Plan Cover?**

Coverage varies by plan, but common features include:

Important: a TRICARE Supplement plan is **secondary**. If TRICARE doesn’t cover the service at all, the supplement typically won’t either. Always review your policy terms, which SelmanCo explains further on its **health care providers page**.

### **Frequently Asked Questions**

**Q: Do I still need TRICARE if I have a supplement plan?**  
Yes. A TRICARE Supplement plan does not replace your TRICARE benefits. It supplements them. You must have TRICARE first, because the supplement pays only after TRICARE has paid its portion.

**Q: Will a supplement pay for services TRICARE denies?**  
Generally no. Because the supplement is secondary to TRICARE, it typically only helps with costs TRICARE already approves. Services TRICARE doesn’t cover usually won’t be covered by the supplement. Additional clarification can be found on **SelmanCo’s health care providers page**.

**Q: Are TRICARE Supplements available everywhere?**  
Availability can vary by state, and some plans may not be offered in all locations. Always confirm plan availability before enrolling.

### **Which Should I Choose?**

### **Final Thoughts**

Understanding how TRICARE and TRICARE Supplement Insurance work together empowers you to make informed decisions about your healthcare finances. TRICARE provides essential coverage backed by the Department of Defense, and a supplement plan from SelmanCo can help **fill in cost gaps**, giving you greater peace of mind.
