Which of the following is a requirement for claims submission under HIPAA?

The requirement for claims submission under HIPAA is that claims must be in electronic format. This mandate stems from the need to streamline healthcare transactions and ensure consistency across the healthcare system. HIPAA emphasizes the importance of electronic transactions to facilitate faster processing, reduce errors, and improve overall efficiency in claims management.

Submitting claims electronically allows for easier tracking and management of claims, reduces administrative costs, and enhances patient privacy by minimizing the handling of sensitive information, such as social security numbers, in paper form. The transition to electronic submissions is a key part of HIPAA's goal to modernize healthcare operations and safeguard patient data.

The other options reflect misunderstandings of HIPAA requirements: claims do not need to be submitted on paper, social security numbers are not mandatory for every claim submission, and specific time frames for submission can vary based on different regulations and payer requirements rather than a strict 10-day rule under HIPAA.
