Why this matters

Verifying the remittance against the claim and account is a foundational step in billing reconciliation. Failure to do so can lead to delayed payments, incorrect adjustments, and ultimately, financial losses for the provider. This action directly impacts the revenue cycle and the provider's ability to accurately track and manage its financial transactions.

Answer choices

A. Match the remittance to the claim and account to verify the discrepancy.
B. File an appeal immediately to dispute the contractual adjustment.
C. Submit a revised claim to correct the duplicate submission.
D. Contact the patient to inform them of the contractual adjustment.

Correct answer
