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.
