Risk watchlist

Common reasons claims get denied

These show up most often in adjuster decisions for this claim type. Knowing them in advance usually changes how you document the loss.

Appeal filed after internal deadline

Check the denial letter for appeal windows—some are 30–60 days.

New evidence not tied to cited provisions

Address each policy clause the adjuster relied on.

Release already signed

Appeals after signing a release are usually barred—get counsel.

Excluded driver or business use upheld

Focus appeal on facts disproving the exclusion trigger.

Late notice upheld without prejudice argument

Show the delay did not harm investigation.

Timeline

What slows a claim down

Most delays come from these causes — often fixable with a single phone call or follow-up email.

Supervisor queue

Internal appeals often take 15–30 business days.

Independent medical exam ordered

Common in injury denials—comply or document refusal.

DOI inquiry period

Regulator complaints may add 30–60 days but keep file moving.

Be ready

Supplemental documents you may be asked for

Adjusters routinely request additional records during review. Being ready keeps a claim from stalling.

Total loss valuation dispute on appeal

Market comps and condition documentation.

Coverage counsel involved

Copy of reservation-of-rights letters from your insurer.

Escalation

If your claim is denied, delayed, or short-paid

Concrete next steps for readers who hit a wall. Each one is a recognized consumer right or documented escalation path.

2Request the denial or short-pay decision in writing citing specific policy language.
3Compare your file against the related Insurhi playbook before escalating.
4If the carrier misses your state's prompt-pay timeline, send a written demand referencing the statute.

Paper trail

Talking to the carrier and your state regulator

How you communicate matters. These notes help you keep a written paper trail and use language carriers and state DOIs recognize.

Confirm verbal commitments in a follow-up email with deadlines.
Log adjuster name, direct line, and supervisor contact on every call.
Use claim number and policy number in every email subject line.
