Which action helps ensure accuracy when entering payer information on a CMS-1500 claim?

• A. Entering the prior authorization number in the claim
• B. Verifying the patient’s demographics in Block 2
• C. Submitting claims without demographics
• D. Checking the CPT codes for accuracy

Answer: (B)

Verifying the patient’s demographics in Block 2 helps ensure accuracy because this section contains the patient identifiers the payer uses to locate the correct records and match the claim to the right insurance. When the patient’s name, birth date, sex, and address are accurate, the claim aligns with the payer’s profile, reducing the chance of rejections for identity or eligibility mismatches and speeding processing. While prior authorization, CPT coding, or submitting without demographics can be relevant in other contexts, they don’t directly ensure that the payer information correctly corresponds to the patient in the insurer’s system.
