What changed

The Centers for Medicare & Medicaid Services (CMS) has released a series of transmittals in late December 2024 that introduce significant policy and coverage updates for Medicare. These include changes to the payment for Tribal Federally Qualified Health Centers, updates to the Medicare Benefit Policy Manual for dental services, revised billing instructions for expedited determinations, adjustments to the Medicare Adjudication Portal for dental claims, and modifications to payment for specific HCPCS codes. The transmittals also address updates to cost reporting forms and policies for Organ Procurement Organizations.

Healthcare providers and entities billing Medicare must review these transmittals to understand the specific policy changes and ensure compliance. Key implementation dates range from January 2025 to March 2025, requiring prompt attention to update billing systems, operational procedures, and provider education materials. Failure to adhere to these updated policies could result in claim rejections or payment disruptions.

What to do next

Review Medicare transmittals issued in late December 2024 for policy and coverage updates.
Update billing systems and operational procedures to align with new implementation dates (Jan-Mar 2025).
Ensure provider education materials reflect the changes outlined in the transmittals.
