The document also showed the Business Office manager (BOM) called Resident 15's responsible party on 3/21/25, notifying the responsible party of the Medicare Covered Part A stay was ending on 3/24/25. Review of Resident 15's SNF ABN showed Medicare doesn't pay for everything even some care that you and your health care provider think you need. The Skilled Nursing Facility Advanced Beneficiary Notice of Non-Coverage or its utilization review committee believes that the care listed below does not meet the Medicare coverage requirement. Beginning 3/25/25, you may have to pay out of pocket for this care if you do not have insurance that may cover those costs. Further review of the document did not show the signature of Resident 15 and/or the resident's authorized representative. Review of Resident 15's Optional Form to Document Alternate Delivery for the NOMNC showed Resident 15's responsible party was contacted via telephone call on 3/21/25, and via email on 3/24/25.

If a bed rail is needed, the facility must (1) assess a resident for safety risk; (2) review these risks and benefits with the resident/representative; (3) get informed consent; and (4) Correctly install and maintain the bed rail. **NOTE- TERMS IN BRACKETS HAVE BEEN EDITED TO PROTECT CONFIDENTIALITY** Based on observation, interview, medical record review, and facility P&P review, the facility failed to ensure one of three final sampled residents (Resident 7) remained free from an accident/hazards due to the use of the side rails/ grab bars. * The facility failed to ensure the informed consent was obtained and completed for Resident 7's bilateral U grab bars. This failure had the potential to put the resident at risk for entrapment and serious injuries. Findings: According to FDA.gov, deaths and serious injuries related to side rail entrapment have occurred with the use of side rails. The FDA issued a Safety Alert entitled Entrapment Hazards with Hospital Bed Side Rails. Residents most at risk for entrapment are those who are frail or elderly or those who have conditions such as agitation, delirium, confusion, pain, uncontrolled body movement, hypoxia, fecal impaction, acute urinary retention, etc., that may cause them to move about the bed or try to exit from the bed. Entrapment may occur when a resident is caught between the mattress and bed rail or in the bed rail itself. Inappropriate positioning or other care related activities could contribute to the risk of entrapment. Review of the facility's P&P titled Bed Rails revised on 5/30/24, showed the ordering physician will obtain informed consent from the resident/ resident representative prior to the use of bed rails. On 9/15/25 at 0943 hours, during the initial tour of the facility, Resident 7 was observed lying in bed awake and verbally responsive. Resident 7's bed was observed with the bilateral U grab bars elevated. On 9/17/25 at 0951 hours, a follow up observation was conducted with Resident 7. Resident 7 was observed lying in bed awake and verbally responsive. Resident 7's bed was observed with the bilateral U grab bars elevated. Medical record review for Resident 7 was initiated on 9/15/25. Resident 7 was admitted to the facility on [DATE]. Review of Resident 7's H&P examination dated 7/24/25, showed Resident 7 was unable to make her own medical decisions. Review of Resident 7's Quarterly MDS assessment dated [DATE], showed Resident 7 had a BIMS of 9, indicating moderate impaired cognition. Review of Resident 7's Order Summary Report for 9/2025 showed a physician's order dated 7/28/22, for the bilateral grab bars for the ADL care changes, mobility, positioning, and as an enabler. Further review of Resident 7's medical record failed to show the informed consent was obtained for the use of the bilateral U grab bars. On 9/17/25 at 1059 hours, an interview was conducted with CNA 6. CNA 6 stated Resident 7 used the bilateral U grab bars for turning and repositioning while in bed. On 9/18/25 at 1026 hours, an interview and concurrent medical record review was conducted with LVN 1. LVN 1 stated Resident 7 currently used the bilateral U grab bars for turning in bed. LVN 1 verified the above findings and stated the informed consent should be obtained for safety measures and updated when the physician's order changed. On 9/22/25 at 1313 hours, an interview was conducted with the Administrator and DON. The Administrator and DON were informed and acknowledged the above findings.
