TRICARE surgery denied: how to appeal

Quick answer

If TRICARE denied your surgery, you can appeal, and the plan must give you its file and the criteria it used. You have 90 days from the notice (TRICARE) to file. The date printed on your denial notice controls; it can only be later than these floors, never earlier.

Why TRICARE denies surgery

TRICARE is the U.S. Department of Defense health program covering active-duty servicemembers, retirees, and eligible family members. Appeals are governed by 32 CFR Part 199, administered by regional contractors (Humana Military and TriWest), with final review by the Defense Health Agency (DHA).

For surgery specifically: Surgical denials are issued before the procedure (prior authorization) or after (claim denial). Both have appeal paths. The strategy depends on which.

The law that controls this appeal

Medical-necessity review against the plan's own clinical criteria (MCG or InterQual), which the plan must disclose on request under the rules that govern your plan (see the table above).

Note for TRICARE: where the standard above cites ERISA or the ACA appeal rules, those describe employer and Marketplace plans. The windows and levels that apply to TRICARE are in the table below.

TRICARE appeals: the rule, the deadline and the next level, by plan type

TRICARE is a federal programme with its own appeal rules. State external review, ERISA and the ACA appeal rules do not apply.

Plan type	Rule that governs	File your appeal within	The plan must answer	If the plan says no again
TRICARE Active-duty families, retirees and their families. Claims are handled by Humana Military (East) or TriWest (West) under the Defense Health Agency.	32 CFR 199.10 (appeal and hearing procedures) and the TRICARE Operations Manual, Chapter 12. ERISA, the ACA appeal rules and state external review do not apply.	Reconsideration: 90 days from the date of the notice of the initial determination. Formal review by the Defense Health Agency: 60 days from the reconsideration decision. Hearing: 60 days from the formal-review decision (32 CFR 199.10).	Expedited review is available for pre-admission and pre-authorization denials; the contractor's clock for a standard reconsideration is stated in the letter.	Formal review by the DHA, an independent hearing when the amount in controversy meets the threshold in 32 CFR 199.10(d), and a final decision by the DHA Director.

TRICARE

What you can demand. The sponsor, the beneficiary, a participating provider or an appointed representative can appeal. Ask the contractor for the file and the medical-necessity criteria it applied.

How to open the appeal. Cite 32 CFR 199.10 and the benefit rule in 32 CFR 199.4: state the appeal type, address it to the regional contractor named on the letter, and request the criteria used.

What TRICARE denies for surgery

The surgery services most often denied:

Bariatric surgery (gastric sleeve, bypass, RYGB)
Orthopedic, knee, hip, shoulder replacement
Spine surgery (fusion, decompression)
Cardiac (CABG, valve replacement, ablation)
Reconstructive and plastic surgery deemed cosmetic
Bilateral mastectomy and reconstruction

Why surgery claims get denied

A typical TRICARE surgery denial almost always cites one of these reasons. Each one maps to a specific rebuttal in the appeal:

Plan claims procedure is 'not medically necessary'
Conservative therapy (PT, weight loss, etc.) not documented
Wrong CPT/ICD coding submitted by surgeon's office
Carrier deems procedure 'experimental' or 'investigational'
Pre-existing condition exclusion (rare under ACA)

The TRICARE appeal process

Appeal levels: Contractor reconsideration, formal review by DHA, then independent hearing (above the amount-in-controversy threshold), then DHA Director final decision.

Carrier timing: 90 days from denial for reconsideration; 60 days from each subsequent adverse decision for the next level. Urgent / pre-authorization timelines compress to 72 hours.

Surgery timing for TRICARE: the filing windows and decision clocks in the table above apply; the date on the notice controls.

What we know about TRICARE: TRICARE rules are federal, state DOI external review does not apply. We brief appeals against 32 CFR Part 199 and the TRICARE Operations Manual specifically.

Common TRICARE denial patterns for surgery

Regional contractor reconsideration first. TRICARE appeals begin with reconsideration by the regional managed care support contractor, Humana Military (East) or TriWest (West). The reconsideration request must be in writing and is typically due within 90 days of the initial denial.
Formal review by DHA. After contractor reconsideration, members can request a formal review by the Defense Health Agency. This step is the gateway to a hearing and is the prerequisite to any further federal review.
Independent hearing for higher-dollar cases. TRICARE provides an independent hearing for appeals meeting a minimum amount-in-controversy threshold. The hearing officer's recommendation goes to the DHA Director for a final agency decision.

How to win your TRICARE surgery appeal

Strategy for surgery: Force the carrier to disclose the clinical criteria they used. Have the surgeon write a letter of medical necessity addressing each criterion. Attach prior conservative-therapy documentation. Request a peer-to-peer review with the plan's medical director.

Filed against TRICARE, that strategy rides on this procedural spine:

Procedural-rights anchor. Cite 32 CFR 199.10 and the benefit rule in 32 CFR 199.4: state the appeal type, address it to the regional contractor named on the letter, and request the criteria used.
Criteria-disclosure demand. TRICARE frequently denies on "not medically necessary" without disclosing the clinical criteria applied. Once disclosed, those criteria become the rebuttal map.
Controlling-standard citation. Medical-necessity review against the plan's own clinical criteria (MCG or InterQual), which the plan must disclose on request under the rules that govern your plan (see the table above).
Treating-provider attestation. A letter from the treating physician addressing each criterion in TRICARE's own policy language. This is the single strongest evidentiary element.
Requested action. A specific demand to reverse the surgery denial and approve the service, not a general "please reconsider."

Documents you'll need for your TRICARE surgery appeal

The denial letter
Insurance card (front + back)
Surgeon's pre-operative notes
Imaging reports (MRI, X-ray, CT)
Conservative-therapy records (PT, medication trials)

What a surgery appeal can recover

Typical recovery for surgery cases runs $5,000 - $150,000+ depending on procedure. The exact figure depends on the specific service and your plan's contracted rates.

TRICARE surgery appeals: frequently asked questions

Can I appeal your TRICARE surgery denial?

Yes. Pre-service (prior authorization) and post-service surgical denials are both appealable. Force TRICARE to disclose the clinical criteria (MCG or InterQual) it applied, then have your surgeon rebut each criterion in a letter of medical necessity.

Why did TRICARE call my surgery 'not medically necessary'?

Most surgical denials cite unmet criteria or missing documentation of conservative therapy such as physical therapy, weight loss, or medication trials. Documenting those prior treatments and mapping them to the carrier's own criteria is the core of the appeal.

What Apellica does for TRICARE surgery appeals

We file appeals against TRICARE specifically configured to its internal review process. Every surgery appeal embeds the criteria-disclosure demand, the procedural-rights anchor, the controlling-standard citation above, treating-provider attestation language, and the peer-reviewed evidence relevant to the denied service.

Cost: $0 upfront. We work on contingency for TRICARE appeals, if the appeal succeeds, we collect a percentage of the recovered claim value. If it fails, you owe nothing.
