This suspension is typically triggered to resolve Coordination of Benefits (COB) discrepancies, verify primary versus secondary coverage, or investigate potential third-party liability such as a work-related or auto accident.

Dear Appeals Department,

I am writing to appeal the denial of the above-referenced claim, which was denied with code 98: "Benefits suspended - investigation in progress".

We are appealing the denial of this claim, designated under Denial Code 98 (Benefits suspended - investigation in progress), as the medical services rendered were medically necessary and the patient's active coverage has been verified. Under CMS and industry standard Coordination of Benefits (COB) guidelines, the timely adjudication of claims should not be indefinitely delayed when valid coverage is established. We have confirmed with the beneficiary that all primary and secondary payer information is current, and no third-party liability applies to this specific service. Attached, please find the updated COB documentation, the complete medical record, and proof of the patient's active enrollment. We request that you immediately resolve the suspension and process this claim for reimbursement.

Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].

We respectfully request that you reprocess this claim for payment.

Sincerely,
