Inaccurate MDS Coding for Resident With Stage 3 Pressure Ulcers
Summary
The facility failed to ensure the accuracy of the Minimum Data Set (MDS) assessment for one resident with pressure ulcers/injuries. The quarterly MDS with an Assessment Reference Date of 02/17/2026 documented that the resident was not at risk for developing pressure ulcers/injuries and had no unhealed pressure ulcers/injuries. This coding was completed despite existing documentation in the resident’s medical record and care plan indicating the presence of pressure ulcers. The facility reported that it followed the CMS LTC Facility RAI 3.0 User’s Manual for MDS completion, which requires coding of any pressure ulcer/injury present during the 7‑day look‑back period. The resident, admitted on 08/05/2025, had a medical history including hemiplegia and hemiparesis following a nontraumatic subarachnoid hemorrhage affecting the left non-dominant side and had a BIMS score of 10, indicating moderate cognitive impairment. The resident’s care plan, initiated on 08/07/2025, identified them as at risk for skin breakdown related to incontinence, limited mobility, and existing pressure ulcers on the right gluteus/sacral area, left heel, and left lateral ankle. Progress notes dated 01/28/2026 by the wound physician documented an unhealed Stage 3 pressure ulcer on the sacrum, and notes dated 02/12/2026 by the evening nursing supervisor documented an in-house acquired Stage 3 pressure ulcer on the left gluteus. During interviews, the DON confirmed the pressure ulcer should have been coded on the MDS, and the MDS Coordinator acknowledged she missed coding the Stage 3 pressure ulcer, while the Administrator stated that a Stage 3 pressure ulcer should be reflected on the MDS.
