Reimbursement and Interoperability Standards Update (May 2026)

Details

This article provides critical updates on healthcare payment and regulatory compliance, compiled by the Michigan State Medical Society (MSMS). A major highlight is the Centers for Medicare & Medicaid Services' proposed rule (CMS-0062-P) concerning 2026 Interoperability Standards and Prior Authorization. This proposal extends electronic prior authorization requirements to prescription drugs, mandating that payers adopt faster decision timelines, enhance transparency, and support standardized APIs. Furthermore, the Department of Health and Human Services (HHS) proposes adopting FHIR-based standards for prior authorization transactions across all HIPAA-covered entities, underscoring the industry shift toward standardized data exchange. Individual health plans also issue specific guidance on billing practices, such as setting limits ($99,999.99) for professional electronic claims (837P) and requiring multiple claims submission when charges exceed this limit. These updates are vital for providers to ensure compliance with evolving federal regulations and maximize accurate reimbursement in the digital age.
