TRICARE Appeal Letter Template 2026: Four Letters for Reconsiderations, Appeals, and Network Providers

Why One Generic TRICARE Appeal Letter Isn't Enough

A single all-purpose letter fails on TRICARE because the program checks three things before it reviews your argument: whether the issue is a reconsideration or an appeal, whether you're allowed to file it, and which level you're at. Commercial templates skip all three, since most commercial plans let any treating provider appeal.

TRICARE appeals run under 32 CFR 199.10. Under that rule, a request has to be in writing, state the specific matter in dispute, and include a copy of the initial determination. The same section says a nonparticipating provider is not a party to the initial determination and may not appeal. The regional contractors add a further rule on top: network providers aren't appropriate appealing parties unless the beneficiary appoints them in writing.

For the full two-track process (factual vs. medical necessity, the $50 and $300 escalation thresholds, and the Point-of-Service trap), see the TRICARE appeal guide for providers. This post is the letter set: which one to send, and the exact language for each.

Step 1: Decide Whether It's a Reconsideration or an Appeal

If you're disputing how a claim was processed, send a reconsideration. If you're disputing a coverage or medical necessity decision, send an appeal. TriWest's provider page draws that line explicitly, and Humana Military separates "allowable charge reviews" from medical necessity appeals the same way.

Sources: TriWest reconsiderations and appeals; Humana Military appeals and reconsideration; TRICARE West authorization appeals (updated March 19, 2026).

For the general version of this fork outside TRICARE, see reconsideration vs. appeal.

Step 2: Confirm You Can File the Appeal Yourself

Non-network participating providers can file appeals in their own name. Network providers need a signed AOR from the beneficiary, and non-participating providers can't appeal at all. This is where most TRICARE provider appeals stall. A letter from a network practice with no AOR attached is treated as filed by someone who isn't an appropriate appealing party, so the clock keeps running while nothing is reviewed.

Humana Military's appeal page says "network providers cannot appeal without an AOR specific to the appeal being requested" (Humana Military). The West Region page says the same thing: "Network participating providers can't file an appeal without a signed Authorization of Representative form" (TRICARE West). TriWest's form is titled Appointment of Representative and Authorization to Disclose Information, and it asks for the denied authorization or claim numbers along with the beneficiary's signature. Use your region's current form.

Where to Send Each Letter

Reconsiderations and appeals go to different addresses in both regions, so match the address to the letter. These are the destinations published on the contractors' pages as of October 2026. If the denial letter lists a different address, use the denial letter.

Letter 1: Claim Reconsideration Request

Use this letter when the claim paid wrong or denied for a processing reason: allowed amount, timely filing, OHI, a coding edit, or a no-authorization penalty. TriWest requires that it arrive no later than 90 days from the remittance date. Include whatever proves the processing error, such as a clearinghouse acceptance report for a timely filing denial or the primary EOB for an OHI issue.

Letter 2: Appeal From a Non-Network Participating Provider

Use this letter when you're a non-network participating provider and the claim or authorization was denied as not medically necessary, as a policy limitation, or as POS-only for emergency care. The appeal has to be written, signed, state the issue in dispute, and include the initial denial and supporting documents (TriWest). If records are still being gathered, send the letter on time and say more documents will follow, as TRICARE advises.

APPEAL TYPE
[ ] Medical necessity: care denied as not medically necessary
[ ] Factual: denied as a TRICARE policy limitation / non-covered
[ ] Point-of-Service: processed as POS-only; services were emergency
    care

ISSUE IN DISPUTE
The [EOB / denial letter] states: "[quote the exact denial reason]."
We dispute this determination for the reasons below.

BASIS FOR APPEAL
[Medical necessity: summarize the diagnosis (ICD-10 [code]), the
service (CPT/HCPCS [code]), prior treatments tried and their results,
and why this service is required now. Address each criterion the
denial cited and attach the records that meet it.]

[Factual: identify the TRICARE policy provision the denial relied on
and explain why the service falls within coverage, citing the
applicable TRICARE Policy Manual section or benefit description.]

[POS emergency: describe the presenting symptoms and why the visit
was emergency care rather than a non-referred routine visit; attach
the ED or triage record.]

REQUESTED ACTION
Please reverse the denial and [approve authorization / reprocess the
claim for payment].

ENCLOSURES
1. Copy of the EOB / denial letter dated [date]
2. Letter of medical necessity from [Treating Provider, Credentials]
3. Relevant chart notes, test results, and treatment history

Letter 3: Appeal From a Network Provider With an Appointment of Representative

If you're a TRICARE network provider, file the appeal on the beneficiary's behalf as their appointed representative, and attach the signed AOR. Without the AOR, the contractor can refuse to treat the letter as an appeal. Get the form signed as soon as the denial arrives so the 90-day window isn't spent chasing a signature.

Letter 4: Second-Level Request (DHA Formal Review or TQMC Reconsideration)

If the contractor upholds the denial, the next step depends on the track. For a factual denial with $50 or more in dispute, request a Defense Health Agency formal review, postmarked within 60 days of the appeal decision. For a medical necessity denial, request reconsideration from the TRICARE Quality Monitoring Contractor (TQMC), postmarked within 90 days of the appeal decision (TRICARE). Send it to the address printed in the contractor's decision. The same standing rules apply here, so a network provider still needs the AOR.

[Address exactly as printed in the contractor's appeal decision]

RE: Request for [Formal Review / Reconsideration]
[ ] Formal review: factual determination, amount in dispute $50+
[ ] Reconsideration: medical necessity determination (TQMC)
Appealing Party: [Provider Name / Beneficiary Name]
[Representative: Provider/Practice Name, if filing under an AOR]
Beneficiary: [Name] | DOB: [MM/DD/YYYY]
Sponsor DoD Benefits Number (or SSN, last 4): [Number]
[Claim / Authorization] Number: [Number]
Contractor Appeal Decision Date: [MM/DD/YYYY]
Amount in Dispute: $[Amount]

REQUEST
We request [formal review / reconsideration] of the enclosed appeal
decision issued by [TriWest Healthcare Alliance / Humana Military] on
[date], which upheld the denial of [service, CPT/HCPCS code].

WHY THE APPEAL DECISION IS INCORRECT
1. The decision states: "[quote its rationale]."
2. [Explain the specific error: a criterion misapplied, records
   overlooked, or the wrong policy provision cited.]
3. [Identify any new evidence enclosed that was not available at the
   first level, and explain what it shows.]

ENCLOSURES
1. Copy of the contractor's appeal decision dated [date]
2. Copy of the original denial and the first-level appeal
3. [New or additional clinical documentation]
4. [Signed Appointment of Representative form, if applicable]

This request is submitted within [60 days (formal review) / 90 days
(reconsideration)] of the date on the appeal decision.

Sincerely,

[Provider Name, Credentials] | NPI: [Number]
[Practice Name] | Phone: [Number] | Fax: [Number]

After formal review or TQMC reconsideration, disputes of $300 or more can go to an independent hearing. Request it within 60 days of the formal review decision. The hearing officer issues a recommended decision, and the DHA director (or a designee) or the Assistant Secretary of Defense for Health Affairs makes the final call (TRICARE). Below $300, the second-level decision is final.

Deadlines Every TRICARE Letter Has to Meet

Count from the date on the remittance, EOB, or decision letter, and mail with a postmark you can prove. Under 32 CFR 199.10, a request is deemed filed on the date it's mailed and postmarked, or on the date received if there's no postmark. The contractors' own pages phrase some of these clocks as "received," so leave margin.

Sources: TRICARE appeals (updated October 21, 2026); TriWest; TRICARE West authorization appeals. For how these compare with commercial and Medicare clocks, see insurance appeal deadlines.

Mistakes That Get TRICARE Letters Rejected or Delayed

Most rejected TRICARE letters fail on routing or standing, not on the clinical argument.

• No AOR on a network-provider appeal. The contractor can treat it as filed by an improper party. Have the AOR signed at intake.
• Appealing a processing dispute. Allowed-amount, OHI, and timely filing issues go to the reconsideration address, not the appeals box.
• Using the old region map. Since January 1, 2025, TriWest has handled the West Region, including Arkansas, Illinois, Louisiana, Oklahoma, Texas, and Wisconsin. Route by the beneficiary's region, not your practice address. The TRICARE appeal guide covers the realignment.
• Appealing a POS cost-share that wasn't emergency care. Most Point-of-Service determinations aren't appealable. A missing referral is fixed with a referral.
• Waiting for complete records. Send the letter inside the window and say more documentation will follow.
• Treating a medical-records denial as an appeal. TriWest sends those to a separate records address with its own cover sheet.

If a claim seems stalled rather than denied, confirm its status first. The appeal status call script works for contractor calls too.

How Muni Appeals Helps With TRICARE Letters

Muni Appeals helps staff organize an uploaded denial and supporting evidence, research the appeal, and prepare a draft for review. For TRICARE, staff must determine whether to request reconsideration or appeal, select the contractor and submission channel, confirm standing and any AOR requirement, and verify the controlling deadline against the notice and current contractor instructions. Staff review the draft, attach the required records, and submit it through the contractor's channel.

For the clinical core of Letters 2 through 4, use the medical necessity justification letter guide. Practices that also see VA Community Care patients can compare the VA Community Care appeal guide, where TriWest is also a contractor but the reconsideration rules differ.

Frequently Asked Questions

Can a TRICARE network provider file an appeal?

Not in its own name. Humana Military and the TRICARE West Region both state that network providers can't appeal without a signed Appointment of Representative form from the beneficiary. With the AOR attached, the network provider files as the beneficiary's representative.

What is the difference between a TRICARE reconsideration and an appeal?

A reconsideration disputes how a processed claim paid, for example an allowed amount, a timely filing denial, other health insurance, or a no-authorization penalty. An appeal disputes a denial as not medically necessary, a policy limitation, or a POS-only determination for emergency care. They go to different addresses in both regions.

How long do I have to send a TRICARE appeal letter?

Ninety days from the date on the EOB, remittance, or denial for routine claim and authorization appeals, and three calendar days for an expedited authorization appeal. Second-level requests are due within 60 days (DHA formal review) or 90 days (TQMC reconsideration) of the contractor's appeal decision.

Can a non-participating provider appeal a TRICARE denial?

No. Under 32 CFR 199.10, a nonparticipating provider is not a party to the initial determination and may not appeal. The beneficiary can appeal or appoint a representative.

Where do I send a TRICARE East appeal letter?

Humana Military Appeals, PO Box 740044, Louisville, KY 40201-7444, fax (877) 850-1046, or online at humanamilitary.com/appeal, which Humana Military lists as the preferred method. Allowable charge reviews go to Humana Military Customer Service, PO Box 202146, Florence, SC 29502-2146.

Where do I send a TRICARE West appeal letter?

Claim appeals go to TRICARE West Claims Appeals, P.O. Box 2777, Virginia Beach, VA 23450 (fax 1-866-670-4330). Authorization appeals go to TriWest's Appeals and Reconsideration Department, P.O. Box 2636, Virginia Beach, VA 23450 (fax 866-852-1919). Reconsiderations go to TRICARE West Correspondence, P.O. Box 2748.

What should a TRICARE appeal letter include?

It must be in writing and signed by the appealing party or its representative. It should state the specific issue in dispute and include a copy of the initial denial (EOB or remittance) plus supporting documentation. Network providers also need the signed AOR.

Send the Right TRICARE Letter the First Time

On TRICARE, the letter that wins is usually the one that went to the right box, from a party allowed to send it, inside the right window. Match the request type first, check network status second, and then make the clinical case.

Muni Appeals helps practices:

• Organize uploaded denials and supporting evidence
• Research and draft appeal arguments for staff review
• Prepare a draft that staff check against the contractor's current requirements
