Internal vs. External Appeal for a Pediatric Claim: A Parent's Guide

Opening a letter that says your child's claim or prior authorization was denied is stressful. The good news: a denial is rarely the final word. Most health plans give you two layers of appeal — an internal appeal and an external appeal — and understanding the difference helps you move through the process calmly and in the right order. This guide explains what each one is, how they connect, and how to stay organized along the way. It's about navigation and paperwork, not medical advice — your child's clinical questions always belong with their licensed providers.

What Is an Internal Appeal?

An internal appeal is your request for the insurance company itself to look again at a decision it made. You're asking the same plan that issued the denial to re-review the claim, usually with additional information attached — such as a letter of medical necessity from your child's provider, records, or corrected billing codes.

Internal appeals are almost always the first step. The denial letter you received should spell out how to file one, the deadline (often 180 days from the denial), and where to send it. Plans typically have set timelines to respond — faster for urgent situations and longer for standard reviews. Keep every letter, fax confirmation, and reference number as you go.

What Is an External Appeal?

An external appeal — sometimes called an independent or external review — moves the decision outside the insurance company. An independent third-party reviewer, not connected to your plan, looks at the case and makes a decision the plan must honor.

External review generally becomes available after you've completed the internal appeal and the plan still says no (though some urgent cases can run both at once). This is a powerful step because the decision no longer rests with the company that originally denied the claim. Depending on your plan type and whether it's regulated by Arizona or by federal rules, the external review may go through a state process or a federally administered one — the final denial letter from your internal appeal should tell you which path applies and how to request it.

Internal vs. External Appeal: What's the Difference?

Who decides: An internal appeal is reviewed by your insurance plan. An external appeal is reviewed by an independent organization with no stake in the outcome.

When you use each: Internal comes first; external typically follows an unsuccessful internal appeal.

How binding it is: The external reviewer's decision is binding on the plan, which is why many families find it reassuring.

Do I Have to Do an Internal Appeal Before an External One?

In most cases, yes. Health plans generally require you to exhaust the internal appeal first, and the external reviewer will usually want to see that you completed it. The main exception is urgent situations involving your child's health, where some plans allow you to request an external review at the same time as, or instead of waiting on, the internal process. Your denial letter and your plan's member services line are the most reliable sources for which rules apply to your specific policy.

What Information Should I Gather for Either Appeal?

Strong appeals tend to share the same building blocks, no matter the level:

• The exact denial letter and the reason code or language it used
• Your child's plan ID and the relevant claim or authorization number
• A letter of medical necessity or supporting notes from your child's provider
• Any records, test results, or prior approvals that relate to the denied service
• A simple timeline of dates, calls, and reference numbers

Submitting the same organized packet at each level saves you from rebuilding it later. Note the deadline on each letter the moment it arrives, and send everything in a way you can track.
