By: Christina Panos, RHIA, ODS

At a glance: CMS has finalized multiple FY 2027 payment system updates impacting inpatient psychiatric facilities, skilled nursing facilities, inpatient rehabilitation facilities, hospices, inpatient acute care hospitals, and long-term care hospitals. Organizations should prepare for payment rate changes, new reporting requirements, MS-DRG revisions, and ICD-10 coding updates effective October 1, 2026.

It may seem a bit early to be thinking about changing seasons, yet that shift in winds is exactly what comes to mind as the final CMS Prospective Payment System (PPS) rules begin to emerge, continuing to reshape the reimbursement landscape. As healthcare organizations prepare for upcoming coding, payment, and policy changes, having access to current regulatory guidance and monitoring tools such as MediRegs can help teams stay ahead of the transition.

What’s Next

As we await finalization of the calendar year payment system updates, associated fee schedules, and CPT/ HCPCS code sets, it is important to remain vigilant, monitor regulatory developments, and proactively assess the potential impact on operational and reimbursement processes. MediRegs Analytical Tools, for example the MediRegs IPPS MS-DRG Grouper, Calculator, and Analyzer provides IPPS payment logic that enables organizations to model the impact of IPPS changes, including New Technology Add-on Payments (NTAP), early in the fiscal year to support budgeting and planning activities.

Delays in adopting new or revised coding requirements, payment polies or reimbursement guidance can put both compliance and revenue at risk. Connect with us to discover how MediRegs can help.
