Appeal the denial using the reason and instructions in your written notice, whether or not you can prove an AI system was involved. Save the denial letter and explanation of benefits (EOB), check the deadline, and send an internal appeal with evidence addressing the insurer’s stated reason. If waiting could seriously endanger the patient’s health, ask about expedited review. The exact route depends on the plan, state, type of denial, and—for employer coverage—whether the plan is self-funded.
Start with the denial notice, not assumptions about AI
Insurers must explain why they denied a claim and how to dispute the decision. HealthCare.gov says, “You can ask your insurance company to conduct a full and fair review of its decision.” See HealthCare.gov’s guide to appealing an insurance company decision.

Read the denial letter and EOB together. Record the service or treatment, claim number, date of the denial, stated reason, appeal deadline, and where to send the appeal. Check whether the denial concerns care already received or a request for prior authorization: the distinction can affect decision timelines. If the reason is vague, ask the insurer to explain the coverage provision, clinical criteria, and records it relied on. Keep notes of calls and save the notice and EOB.
You can also ask whether an automated tool contributed to the decision and whether a qualified person can review the patient-specific record. Treat these as practical questions, not guaranteed rights to model details or a particular form of human review. The NAIC describes insurers’ AI uses and its 2023 Model Bulletin on AI in insurance, but that does not establish a separate, universal appeal right solely because AI was involved: NAIC: Insurance Topics—Artificial Intelligence.

File an internal appeal with evidence that answers the denial reason
HealthCare.gov’s general guidance says to file an internal appeal within 180 days of receiving the denial notice. Treat that as a general federal guidance window, not a substitute for the deadline in your notice or plan documents; rules can vary. Do not let informal calls consume the time available to file. Follow the notice’s submission instructions and keep a complete copy plus proof of delivery or portal submission. See HealthCare.gov’s internal appeals guidance.
- Identify the claim. Include the member’s name and ID, claim number, date of service or requested service, and the denial date.
- Explain the error. Respond directly to the reason in the notice—for example, identify a factual error, explain why the cited plan provision does not apply, or address the clinical basis for the decision.
- Attach relevant support. Ask the treating clinician to explain the patient’s circumstances and, where relevant, why the service is medically necessary. Include pertinent records and other documents that address the insurer’s stated reason. Send copies, not irreplaceable originals.
- Submit and document. Use the address, portal, or other method in the notice. Save the appeal, attachments, confirmation, and dated notes of any calls.
A clinician’s letter is most useful when it responds to the actual denial rationale and connects the patient’s records to the requested care, rather than simply repeating the request.
Ask for expedited review if waiting could seriously endanger health
If delay could seriously jeopardize the patient’s life or ability to regain maximum function, tell the insurer that the case is urgent and ask how to request an expedited internal appeal. HealthCare.gov’s guidance explains that urgent cases can receive faster review. In some circumstances, external review may also be available before the internal process is finished. The applicable urgency standard, route, and timing depend on the case and review process; use the contact and instructions on the notice. The internal appeals page and external review page describe the general options.

An external review sends an eligible denial to an independent reviewer outside the health plan. HealthCare.gov says a written request is generally due within four months after receiving the denial notice or final determination. Its general guidance describes standard external review decisions as due no later than 45 days and expedited decisions as due no later than 72 hours. These are general procedural timeframes; check the notice and applicable state or federal process for the deadline and timing that govern your case.

Under the described process, the independent reviewer’s decision is binding on the insurer. Not every denial qualifies, and state and federal procedures differ. Follow the external-review instructions in the notice or EOB, and consult HealthCare.gov’s external review guidance. CMS also describes the scope and operation of the HHS-administered federal external review process.
Use the right consumer-help channel for your coverage
A state Consumer Assistance Program or Department of Insurance may help explain appeal rights or direct you to the correct process. If your insurance is job-based, the U.S. Department of Labor’s Employee Benefits Security Administration (EBSA) is another official contact. Which regulator or review process applies can depend on whether coverage is state-regulated and fully insured or provided through a self-funded employer plan. Start with HealthCare.gov’s consumer assistance directory.

What AI involvement does—and does not—establish
A denial involving software is not, by itself, proof that the decision was unlawful or incorrect. The most actionable appeal addresses the plan terms, the facts and records considered, the medical evidence where relevant, and the review rights in the notice.

The report states: “Patients and providers need to be given a rationale for every denial, so that they can determine whether or not to appeal the decision or resubmit the request with modifications.” This is a recommendation, not a binding rule establishing a universal individual right to an AI explanation or human review.

For a claim denial, use the health plan’s appeal process rather than assuming that a Marketplace eligibility appeal is the right route. HealthCare.gov directs consumers to challenge claim denials through their health plan. The process and exact deadline cannot be determined without the state, plan type, denial category, and notice date.
