Important Tennessee CMI Reporting Dates

4/2/2025

The facility-specific Case Mix Index, or CMI, is a key Medicaid rate component for Skilled Nursing Facilities in Tennessee. Ensuring that each facility’s MDS is both accurate and submitted timely is crucial to guaranteeing accurate Medicaid reimbursement. Today, we want to talk about how the CMI is used and some of the key MDS reporting dates.

The Tennessee case mix reimbursement system utilizes a time-weighted CMI value calculation in which resident MDS assessments are weighted based on the number of calendar days the assessment is active within a given semi-annual rate period. This facility-specific CMI score is then an input in the Medicaid per diem reimbursement rate as a value in the Direct Care Case Mix and Direct Care Non-Case Mix component calculations. Because a facility’s CMI is a key component to Medicaid reimbursement, making sure your facility submits its time-weighted case mix index report in a timely manner is crucial.

The following list of criteria assists providers in understanding the 2025 reporting calendar shown at the bottom of this page.
