News in MDS | September 2026

CMS has released the final MDS 3.0 RAI User’s Manual v1.20.11, effective October 1, 2026. One clarification in particular is worth putting in front of every MDS nurse and wound team.

Pressure ulcer present on admission: here’s the scenario

A resident is admitted to the SNF with a pressure ulcer. The ulcer subsequently heals and closes. Months later, the same area reopens at the same stage.

A common reaction may be: “It reopened during the stay, so now it is facility-acquired.”

Not necessarily.

The October 2026 RAI guidance clarifies that when a pressure ulcer/injury that was present on admission closes and later reopens in the same location and at the same stage, it can retain its present-on-admission status. The fact that it reopened later does not, by itself, automatically make it facility-acquired.

Why this matters: MDS coding decisions should follow the current RAI instructions and the resident-specific clinical record—not assumptions based only on when the wound reopened.

What MDS teams should do before October 1

Also changing for FY2027: PDPM

CMS has also released PDPM Grouper V2.5000 for assessments with target dates on or after October 1, 2026. The update supports FY2027 ICD-10 codes and includes changes to clinical-category mappings and NTA comorbidities. MDS and reimbursement teams should make sure they are working from current FY2027 resources when reviewing diagnoses and PDPM.

Knowing the rule is different from knowing how to apply it

This is where MDS education has to go beyond memorizing definitions. The MDS nurse has to take the resident’s clinical picture, documentation, interviews, diagnoses, treatments, assessment timing and RAI instructions and determine how they fit together.

That is exactly what we will practice at Elite MDS Academy.
