Imperial Insurance Company Timely Filing Limit

The most important thing to confirm with Imperial Insurance Company is not just the number of days, but also what event starts the clock. Some payer documents measure from date of service, some from discharge, and some publish different rules for corrected claims or appeals.

At a glance

• Official public-facing materials found in the review clearly state member claim filing windows for some plan/state combinations, but provider-side timely filing limits were not fully located in the accessible excerpts. For enrollee medical claims, the transparency page shows 90 days for Arizona and Texas. Provider manuals reviewed mention claims timeliness generally, but the specific provider timely-filing rule was not extracted from accessible text.

Initial claim filing limits

• Member medical claims: 90 days for AZ
• Member medical claims: 90 days for TX

Corrected claim filing limits

• Not clearly published in the researched sources.

Appeal and reconsideration deadlines

• Not clearly published in the researched sources.

Trigger basis and caveats

• The accessible transparency page is framed around enrollee medical claim submission, not provider contracted claim filing rules.
• Plan/state variation is likely; do not generalize the 90-day enrollee window to all provider claim types without the applicable provider agreement or state-specific manual.
• No definitive provider-side initial, corrected, or appeal deadline was confirmed from the accessible official excerpts.
• A secondary search result from an older California provider manual suggests different contracted-provider claim processing rules, but it was not used as a primary basis because the question asked for current operational guidance and the excerpt was insufficient for universal limits.
