Days to comply
30 days

Summary

Effective August 1, 2026, Michigan Medicaid changes hospital readmission reimbursement policy. Readmissions within 15 days to a DIFFERENT hospital for the same condition now receive full separate payment (instead of bundled payment). Readmissions to the same hospital for related conditions remain bundled as a single episode. Unrelated readmissions are always paid separately regardless of hospital.

Action Required

Before Aug 1, 2026
REQUIREMENTS: - By July 15, 2026: Billing team must review and update hospital discharge/readmission tracking procedures to identify whether readmissions within 15 days are: (1) to same vs. different hospital, and (2) same condition vs. related vs. unrelated condition. - By July 31, 2026: Update billing system logic and claims submission protocols to ensure: • Readmissions within 15 days to DIFFERENT hospital for SAME condition = bill as separate episodes with full payment to both hospitals • Readmissions within 15 days to SAME hospital for RELATED condition = bundle as single episode (no separate payment) • Readmissions for UNRELATED conditions = always bill as separate episodes regardless of hospital - Before August 1, 2026: Train billing and coding staff on new readmission classification requirements. Create decision tree or flowchart documenting condition relationship assessment methodology. - Ongoing: Ensure all existing prior authorization and service criteria limits continue to be applied per previous policy. Clinical disagreements with Medicaid Health Plans must be resolved using existing resolution processes. - NOTE: Implementation is contingent on CMS State Plan Amendment approval. Monitor michigan.gov/medicaidproviders for SPA approval confirmation before full system implementation.
