The PROMPT Act would require the Department of Health and Human Services to send Medicare beneficiaries an explanation of benefits within 30 days after they receive a covered service or item. Currently, no specific deadline exists for sending these explanations, which detail what Medicare paid for, what the beneficiary owes, and other claim information. The bill affects all Medicare beneficiaries and would improve transparency by ensuring they receive timely information about their claims. There is no specific funding amount or implementation timeline mentioned beyond the 30-day requirement for sending explanations of benefits.
