How To Submit Claims To Imperial Insurance Company

For Imperial Insurance Company, the practical claims workflow usually starts with electronic submission guidance and only falls back to paper instructions when the payer documents a mailing address for specific claim types or exceptions. The details below keep the workflow broad instead of reducing it to a single address.

At a glance

• Imperial’s provider-facing pages indicate claims status is available in the provider portal and provider services can be reached by phone. For member-facing paper claims, the transparency page says to complete a claim form, attach an itemized bill, and mail to the address on the form or the state-specific address shown. Public official pages reviewed did not expose a universal electronic payer ID or a single claim submission clearinghouse endpoint.
