The authorization number for a service that was approved before the service was rendered is indicated in which CMS-1500 block?

• A. Block 23
• B. Block 24
• C. Block 21
• D. Block 32

Answer: (A)

Pre-authorization information is used to show that the payer approved the service before it was provided, so the claim needs to reference that approval in the part of the form reserved for authorization or referrals. This block is specifically designated to capture the authorization/referral number, ensuring the claim can be linked to the prior approval and processed correctly. It’s not the place for diagnosis codes (those go in the diagnosis block), dates of service (those go in the dates-of-service area), or facility/service location details (those belong in the blocks for provider and facility information). So, the authorization number for a pre-approved service is recorded in the authorization/referral information block, which is the proper spot for this data.
