§483.420(d)(2) The facility must ensure that all allegations of mistreatment, neglect or abuse,
as well as injuries of unknown source, are reported immediately to the administrator or to
other officials in accordance with State law through established procedures.
Guidance §483.420(d)(2)
Injuries of unknown source that give rise to a suspicion that they may be the result of abuse or
neglect, should be reported immediately.
An injury should be reported as an “injury of unknown source” when:
• The source of the injury was not witnessed by any person and the source of the injury
could not be explained by the client; and
• The injury raises suspicions of possible abuse or neglect because of the extent of the
injury or the location of the injury (e.g., the injury is located in an area not generally
vulnerable to trauma) or the number of injuries observed at one particular point in time
or the incidence of injuries over time.
It is important to note that members of the ICF/IID population are a mobile population and lead
active lives. Therefore, they experience normal day-to-day bumps and minor abrasions as they
go about their lives. These minor occurrences which are not of serious consequence to the
individual and do not present as a suspicious or repetitive injury (as discussed above) should be
recorded by the facility staff once they are aware of them and follow-up should be conducted as
indicated. For injuries that do not rise to the level of reportable “injuries of unknown source”,
the facility should follow its policies and procedures for incident recording, investigation, and
tracking.
The facility must immediately report any suspicious injuries of unknown source and all
allegations of mistreatment, neglect or abuse to a client residing in the facility regardless of who
is the alleged perpetrator (e.g., facility staff, parents, legal guardians, volunteer staff from
outside agencies serving the client, neighbors, or other clients, etc.).
If state law requires reporting to an agency or entity other than the administrator, the Centers
for Medicare & Medicaid Services (CMS) expects the administrator to be notified as well, in
order to ensure facility response to promptly safeguard the client(s).
For the purposes of this regulation “immediately” means there should be no delay between staff
awareness of the occurrence and reporting to the administrator or other officials in accordance
with State law unless the situation is unstable in which case reporting should occur as soon as
the safety of all clients is assured.
