What this denial means
A prior authorization (or “precertification”) denial means the insurer says required pre-approval was not obtained before the service. Crucially, this is usually a procedural denial, not a judgment that you didn’t need the care. If the service met criteria, was urgent, or the gap was administrative, it is frequently reversible.
Why it’s worth appealing
Prior-auth denials are highly appealable because the underlying care was often perfectly appropriate — the problem was paperwork and timing. Urgent and emergency care is commonly exempt from prior-authorization rules entirely.
Show the service met the plan’s medical criteria and argue the authorization gap was administrative, or that the care was urgent or emergent and therefore exempt.
What a strong appeal includes
Attach the clinical records that would have supported authorization, any evidence of urgency, and a clear timeline. Request that the insurer grant a retroactive authorization and process the claim.
How long you have
Appeal windows for prior-auth denials are often shorter — sometimes 60 days — so check the notice carefully and move quickly. Missing the deadline is the most common reason a winnable appeal fails — so act early.
