Internal Appeals And External Review Compared

A denied health claim usually has two routes of challenge, and they work differently. The first asks the insurer to reconsider; the second takes the question away from it entirely.

The internal appeal

An internal appeal is decided by the insurer, though the reviewer must generally be someone not involved in the original decision and, for clinical questions, an appropriate clinician.

Deadlines apply on both sides. The member has a defined window to file, and the insurer has defined periods to decide, shortened where care is urgent.

Most plans provide one or two levels, and completing them is normally a precondition to external review, which is why missing the filing deadline is costly.

What external review changes

External review sends the file to an independent organisation whose reviewers are clinicians without a financial relationship to the insurer.

The determination is usually binding on the insurer, which is the feature that distinguishes it from an internal appeal or a complaint to a regulator.

Eligibility is generally limited to disputes involving medical judgement or rescission, so a straightforward exclusion or benefit-limit question may not qualify.

What each stage decides on

Both stages review a record rather than examining the patient, so the material submitted determines the outcome more than the merits of the underlying case.

Members usually have the right to obtain the claim file, including the criteria applied and any reviewer's report, and to submit additional evidence before the decision.

Requesting that file before writing the appeal is the single most useful step, because it converts an argument about care into an argument about the specific unmet criterion.

Urgent and expedited routes

Where delay would seriously jeopardise health or the ability to regain function, expedited timelines apply and are measured in days rather than weeks.

Expedited external review can often run simultaneously with an internal appeal rather than after it, which removes the sequencing delay.

Urgency must be asserted and, where required, supported by the treating clinician, since a request not marked urgent is processed on standard timelines.

Where the routes end

If external review upholds the denial, remaining options are generally legal rather than administrative, and separate limitation periods apply to them.

Regulators accept complaints in parallel, and while they do not usually overturn individual decisions, they do act on procedural failures such as missed deadlines.

Appeal rights, external review availability and deadlines depend heavily on how a plan is regulated, vary by jurisdiction and change over time.
