TRICARE imaging denied: how to appeal

Quick answer

If TRICARE denied your MRI and imaging, 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 MRI and imaging

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 MRI and imaging specifically: MRI, CT, PET, and other imaging denials are almost always issued at the prior-auth stage. They move fast, and so should the appeal.

The law that controls this appeal

The ACR Appropriateness Criteria are the recognized clinical standard; the plan's radiology-benefit-manager criteria must be disclosed on request.

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 MRI and imaging

The MRI and imaging services most often denied:

MRI of brain, spine, joints, abdomen
CT with contrast
PET scans (oncology, neurology)
Cardiac imaging (echo, MUGA, stress)
Repeat imaging within 90 days

Why MRI and imaging claims get denied

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

Conservative imaging (X-ray, ultrasound) not tried first
Documented symptoms don't match imaging request
Out-of-network imaging facility
Plan claims it's a 'screening,' not diagnostic
ICD coding doesn't justify the CPT requested

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.

Imaging 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 MRI and imaging

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 MRI and imaging appeal

Strategy for MRI and imaging: Start by working out who actually denied it. Most large plans do not review advanced imaging themselves; they delegate it to a radiology benefit manager, and the two that cover most of the market are eviCore (part of Cigna's Evernorth) and Carelon Medical Benefits Management (part of Elevance, formerly AIM Specialty Health). The denial letter or the ordering office will name it. This matters because the criteria being applied are the benefit manager's, not your insurer's general policy, and you are entitled to ask for them in writing. Second, identify which of the two common refusals you actually received. The first is a step-imaging rule: the plan wants a plain X-ray, an ultrasound, or a course of conservative treatment such as physical therapy documented before it will authorise an MRI or CT. The answer is a dated record of what was already tried and what it showed, or a clinical reason that the earlier step is inappropriate here, such as a red-flag symptom. The second is that the chart does not connect the symptoms to the imaging indication, in which case the answer is a note tying the specific findings to the study requested. In both cases the American College of Radiology Appropriateness Criteria are the recognised external standard and are free to cite; where the ordered study matches the ACR rating for that clinical scenario, say so explicitly and give the scenario name. Mark the appeal urgent when delay carries risk, which most plans honour on the ordering physician's signature and which compresses the decision to 72 hours, and ask for a peer-to-peer review the same day, because imaging denials are frequently reversed on that call once a radiologist or the ordering physician explains the indication.

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. The ACR Appropriateness Criteria are the recognized clinical standard; the plan's radiology-benefit-manager criteria must be disclosed on request.
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 MRI and imaging denial and approve the service, not a general "please reconsider."

Documents you'll need for your TRICARE MRI and imaging appeal

Denial letter
Order from referring physician
Symptom history / ordering physician's notes
Prior imaging results (if any)

What a MRI and imaging appeal can recover

Typical recovery for MRI and imaging cases runs $500 - $5,000 per study. The exact figure depends on the specific service and your plan's contracted rates.

TRICARE MRI and imaging appeals: frequently asked questions

Can I appeal your TRICARE MRI or imaging denial?

Yes, and quickly. Imaging denials are almost always issued at prior authorization. Mark the appeal urgent if your ordering physician signs off, which compresses the decision to 72 hours, and request a same-day peer-to-peer review.

Why was my MRI denied as not necessary?

Common reasons are that conservative imaging such as X-ray or ultrasound was not tried first, the symptoms do not match the imaging request, or the ICD diagnosis codes do not justify the CPT ordered. The ACR Appropriateness Criteria are the recognized standard to cite back.

What proves an MRI is medically necessary?

Symptom documentation that maps directly to the imaging-justification diagnosis codes, the ordering physician's notes, and any prior imaging. Citing the ACR Appropriateness Criteria for your clinical scenario is decisive.
