MRI Denied by Insurance in Texas: How to Appeal

Texas is a major insurance market with some of the country's most prominent carriers, but MRI denials are common across all plan types. The good news: Texas has enacted legislation specifically designed to cut down on unnecessary Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization burdens — and you have clear appeal rights.

Why Texas Insurers Deny MRI Claims

Prior authorization denial. Most Texas commercial plans — including those from Blue Cross Blue Shield of Texas, Aetna, Cigna, UnitedHealthcare, and Humana — require prior authorization for MRI scans. If the ordering provider didn't submit the request or the plan deemed it unnecessary, the claim gets denied.

Medical necessity. Texas insurers rely on criteria like InterQual and MCG to evaluate whether an MRI is appropriate. Back pain without red flags, headaches without neurological symptoms, and knee pain early in treatment are frequently flagged as not meeting criteria.

In-network facility required. Texas has large insurer networks but significant regional gaps. An out-of-network imaging center can result in a full denial under HMO plans or dramatically higher cost-sharing under PPOs.

Non-covered service. Some Texas plans classify certain MRI protocols (e.g., functional MRI, MRI with contrast for certain indications) as investigational and exclude them from coverage.

Frequency limitations. Insurers often limit how frequently an MRI can be performed for chronic conditions, leading to denials for follow-up scans within a set time window.

Major Texas Insurers and Their Authorization Practices

Blue Cross Blue Shield of Texas is the dominant carrier in the state and uses a third-party radiology benefit manager (RBM) for imaging authorization. UnitedHealthcare and Aetna have their own prior auth portals. Molina, Centene (Superior Health Plan), and Amerigroup handle Medicaid managed care in Texas, each with their own imaging criteria.

If you are on a Texas Medicaid managed care plan, prior authorization is almost always required for MRI, and the criteria can be stricter than commercial standards.

Texas Gold Carding Law

Texas enacted the Gold Carding law (HB 3459) in 2021, one of the first in the nation. Under this law, if a physician has a 90% or greater prior authorization approval rate with a specific insurer over the prior 12 months, that physician is exempt from requiring prior authorization for services that were previously approved.

Ask your physician whether they are gold-carded with your specific insurer. If so, the authorization step should not be a barrier. If the insurer still denied the claim despite gold card status, that may itself be grounds for an appeal.

How to Appeal an MRI Denial in Texas

Step 1: Get the denial in writing. Your insurer must provide a written denial with the clinical reason and the criteria used. Keep this document — you will need it for your appeal.

Step 2: File an internal appeal. You generally have 180 days from the denial date to file. Include:

• Your physician's letter of medical necessity
• Relevant medical records documenting your symptoms and prior treatments
• Clinical literature supporting MRI for your diagnosis
• A copy of the denial letter

Internal appeals must be resolved within 30 days (standard) or 72 hours (expedited/urgent).

Step 3: Peer-to-peer review. Your physician can request a peer-to-peer call with the insurer's reviewing physician. This is often the fastest route to overturning an imaging denial.

Documenting Medical Necessity for Your Appeal

Texas insurer reviewers and IROs respond to documentation that directly addresses their criteria. Your physician's letter should:

• State the specific diagnosis and symptoms
• Explain why imaging is necessary for diagnosis or treatment planning
• Note what other treatments or imaging modalities have already been tried
• Cite any relevant clinical guidelines (ACR Appropriateness Criteria, for example)
• Address any urgency if the denial involves potential serious pathology
