Falls with major injury represent one of the most challenging clinical events in long-term care. Not only do they cause significant harm to residents, but they also directly impact your facility's quality measures and CMS star ratings. With the October 2025 release of the updated RAI Manual, CMS has clarified definitions around falls and fall-related injuries—and these changes affect how you document, code, and prevent these incidents. Whether you're struggling to improve your quality measures or simply want to ensure your team is coding correctly, understanding the new guidance is essential. In this post, I'll walk you through the updated definitions, explain how falls with major injury impact your quality measures, and share practical prevention strategies to help protect your residents and strengthen your facility's performance.
Per the Long-Term Care Facility Resident Assessment Instrument (RAI) 3.0 User’s Manual, Version 1.20.1, released in October 2025, the definitions for fall and fall with major injury have been updated. (Per CMS process, anything in red is a new addition to this version of the manual.)
A fall is defined as:
CMS’ additional coding tips:
A fall with major injury includes, but is not limited to, traumatic bone fractures, joint dislocations/subluxations, internal organ injuries, amputations, spinal cord injuries, head injuries, and crush injuries.
CMS’ additional coding tips:
The Minimum Data Set (MDS) is a standardized assessment used in Medicare and Medicaid- certified nursing homes to collect demographic and clinical information about residents.
Just like so many areas of the MDS, coding of fall with major injury will affect nursing homes quality measures. Let’s see how it is calculated:
Numerator:
A resident is counted in this measure if any of their assessments during the look-back period indicate a fall with major injury.
Residents are not counted if none of their assessments during the review period recorded whether they had a fall with major injury.
A resident is included in the numerator if any look-back scan assessment indicates a fall with major injury by coding of J1900C = 1 or 2.
Denominator:
All long-stay residents with one or more qualifying assessments in the look-back scan.
Long-stay residents are defined as being in the facility greater than 101 days.
Look-back details:
The look-back scan includes the target assessment and all qualifying earlier assessments within the resident’s episode.
Assessments are included if:
They are within the same episode
They have a qualifying Reason for Assessment (RFA)
Their target date is on or before the target assessment’s date
Their target date is no more than 275 days before the target assessment
Per F Tag 689, the intent of this requirement is to ensure the facility provides an environment that is free from accident hazards over which the facility has control and provides supervision and assistive devices to each resident to prevent avoidable accidents. This includes:
Per the RAI Manual, effective fall prevention and management require a comprehensive approach thru risk identification and intervention strategies.
Risk Identification: Recognizing residents at high risk for falls is essential. This includes evaluating both intrinsic factors (e.g., functional decline, delirium, adverse drug reactions, dehydration, infections) and extrinsic factors (e.g., medication side effects, use of appliances or restraints, environmental hazards).
Intervention Strategies: A fall should prompt a thorough evaluation of a resident’s needs, including rehabilitation services, ambulation aids, environmental modifications, and increased monitoring (e.g., toileting assistance to prevent incontinence-related falls). Falls may also signal the onset of serious medical conditions and should be treated as a sentinel event requiring immediate attention and reassessment of the care plan.
Working through the CMS Critical Elements Pathways (CMS 20127 – Accidents) can help facilities ensure that they have appropriate processes in place to prevent accidents and injuries.
Orthostatic hypotension, a sudden drop in blood pressure when standing, may cause dizziness and instability.
Vision impairments can make it difficult to detect hazards in the environment.
Mobility limitations, such as muscle weakness or poor coordination, reduce a person’s ability to move safely and increase fall risk.
Unsafe behaviors, including rushing, not using assistive devices, or ignoring safety protocols, can significantly heighten the chance of falling.
Falls with major injury are more than isolated incidents - they are sentinel events that reflect the quality of care and safety within long-term care facilities. With updated definitions and coding guidance from CMS, it is critical for providers to understand how these events impact quality measures and regulatory compliance. Accurate documentation, proactive risk identification, and timely interventions are essential to prevent deficiencies and improve resident outcomes. By leveraging tools like the Critical Element Pathways and Appendix PP, facilities can strengthen their fall prevention strategies and ensure a safer environment for all residents. Ultimately, a comprehensive, resident-centered approach to fall management not only supports regulatory standards but also promotes dignity, safety, and quality of life.
