Part A to part B rebilling: understanding the rules in a changing environment

Area of Science:

• Healthcare Policy
• Medicare Reimbursement
• Health Administration

Background:

• A recent Centers for Medicare & Medicaid Services (CMS) ruling allows hospitals to resubmit denied Medicare Part A claims for payment under Medicare Part B.
• A new CMS proposed rule may eliminate this option, creating significant financial challenges for healthcare providers.

Purpose of the Study:

• To analyze the implications of a proposed CMS rule that could restrict hospitals' ability to rebill denied Medicare Part A claims under Medicare Part B.
• To inform hospitals about strategies for responding to the proposed rule and advocating for continued access to Part B rebilling.

Main Methods:

• Analysis of a recent CMS ruling and a proposed rule concerning Medicare claim rebilling.
• Review of potential hospital strategies in response to the proposed rule, including administrative comments and legislative/legal actions.

Main Results:

• The proposed rule, if finalized, would impose barriers to rebilling denied Medicare Part A services under Part B.
• Hospitals have avenues to influence the outcome, including submitting comments to CMS, seeking congressional intervention, or pursuing litigation.

Conclusions:

• Hospitals should actively engage with the proposed rule by submitting comments to CMS.
• Strategic engagement may lead CMS to withdraw the proposed rule or prompt legislative/legal action to preserve Part B rebilling options.
