• Contracted providers must mail the provider dispute resolution form to the address on the form; do not send it to the appeals department.

• For overpayment disputes, written notice must be sent within 30 working days of the overpayment notice.

Caveats

• Claim submission details vary significantly by state and product; the addresses and payer IDs above are the ones explicitly listed in official materials reviewed.
• I did not find a verified electronic payer ID for every possible Imperial product beyond the IDs listed in the provider manuals.
• The exact corrected-claim/void-bill mechanics were not clearly spelled out in the reviewed official sources; the dispute process is the clearest official path for claim reconsideration.
