# Denied Claims: How to Appeal in Tennessee

A denied claim isn't the final word. There's a ladder, and it works: **read the denial letter, appeal inside your plan, and if that fails, ask the state for an independent external review.** Here's each rung, in order.

## Rung 1: Read the denial letter

Your denial letter (sometimes called an Explanation of Benefits or adverse benefit determination) tells you two critical things: **why** the claim was denied, and **your deadline** to appeal. Treat that deadline as the authority — miss it and you can lose the right to appeal entirely. Keep the letter; you'll reference it at every step.

## Rung 2: The internal appeal

File an appeal with your plan — the denial letter and your plan documents explain exactly how. Practical tips that actually matter:

- **Get your doctor involved early.** A letter from your clinician explaining why the care was medically necessary carries real weight.
- **Reference the plan language.** Point to the specific benefit or provision you believe covers the care.
- **Keep copies of everything** you send and receive.
- **Write down names, dates, and reference numbers** for every phone call.

You must **exhaust this step first** — external review isn't available until your plan's internal appeal process is finished.

## Rung 3: Independent external review through TDCI

After your plan's internal appeal is complete, you can request **external review** through the Tennessee Department of Commerce & Insurance (TDCI). Here's what that means:

- **Independent clinicians** with no stake in the outcome re-examine your case — not your insurer, not anyone paid by your insurer.
- It's typically used for denials based on **medical necessity** or because the care was deemed **experimental or investigational**.
- The decision is **generally binding on the plan**. If the reviewers overturn the denial, the plan has to cover the care.

**How to reach TDCI's Consumer Insurance Services:** call (615) 741-2218 or 1-800-342-4029; file online at tn.gov/commerce/insurance/consumer-resources/file-a-complaint.html; or write to 500 James Robertson Parkway, 10th Floor, Nashville, TN 37243-0574.

## If the process itself breaks down

If your plan won't follow the appeal rules — ignoring deadlines, refusing to provide required notices, stonewalling — file a **complaint with TDCI** using the same contacts above. The complaint process and the appeal process are different tools; use the complaint when the *process* is the problem.

## Know which door is yours

Not every plan answers to TDCI. Using the wrong door wastes weeks:

- **Marketplace and most individual plans, plus many small-employer plans:** these are fully insured and regulated by the state — **TDCI** is your agency.
- **Self-funded employer plans** (large or multi-state employers that pay claims themselves rather than buying insurance): regulated by the **U.S. Department of Labor's Employee Benefits Security Administration** — (866) 444-3272. TDCI can't take these cases.
- **TennCare managed-care disputes** (BlueCare, Wellpoint, UHC Community Plan): go through **TennCare**, not TDCI.
- **Medicare questions:** the Tennessee SHIP program offers free, unbiased counseling — 1-877-801-0044.

Not sure which type your plan is? Ask your HR department or benefits administrator whether the plan is self-funded — they're required to tell you.

## Practical tips for the whole process

- **Keep copies of everything.** Every letter, every form, every email — both directions.
- **Log every call:** name, date, time, reference number, and what was said.
- **Don't miss the deadline** in your denial letter. Calendar it the day the letter arrives.
- **Get your doctor involved early**, not after the second denial.
- **Keep paying your premiums** so your coverage stays active while you appeal.
- **Don't ignore the underlying bill.** Ask the provider — in writing if you can — to hold the account while the appeal is pending.

## Frequently asked questions

**My claim was denied. What's the very first thing I should do?**
Read the denial letter carefully: note the reason for the denial and your appeal deadline. Calendar the deadline immediately, then start the plan's internal appeal.

**What's the difference between an internal appeal and external review?**
An internal appeal asks your plan to reconsider its own decision. External review — available only after the internal appeal is exhausted — puts your case before independent clinicians through TDCI, and the decision is generally binding on the plan.

**Who handles external review in Tennessee?**
The Tennessee Department of Commerce & Insurance (TDCI), Consumer Insurance Services: (615) 741-2218 or 1-800-342-4029.

**Is the external review decision binding on my plan?**
Generally, yes. If the independent reviewers overturn the denial, the plan must cover the care.

**How long do I have to file an appeal?**
Your denial letter states your filing deadline — treat it as the authority. For ACA plans, federal rules require at least 180 days from the denial to file an internal appeal, but file as early as you can.

**My plan is through my employer's self-funded plan. Where do I appeal?**
Start with the plan's own internal appeal process, then — for external help — contact the U.S. Department of Labor's Employee Benefits Security Administration at (866) 444-3272. TDCI doesn't regulate self-funded plans.

**I'm on TennCare and my health plan denied something. What do I do?**
TennCare managed-care disputes go through TennCare, not TDCI. Follow the appeal instructions in your TennCare notices.

**What if the appeal process itself isn't working?**
File a complaint with TDCI's Consumer Insurance Services — (615) 741-2218 or 1-800-342-4029, or the online complaint form at tn.gov/commerce/insurance/consumer-resources/file-a-complaint.html.

**Should I keep paying the bill while I appeal?**
Don't ignore it. Ask the provider to hold the account while the appeal is pending — in writing if you can — and keep paying your premiums so your coverage stays active.
