Immediately: ensure resident safety and separate the accused from resident contact. Nothing else matters if this is not done first.
Immediately: report as required by the state mandatory reporter statute, within the statutory timeframe, without waiting for the internal investigation. Document the time and method of the report.
Immediately: engage counsel. If the allegation involves potential criminal conduct, that engagement should happen before anyone is interviewed.
Same day: notify the carrier as a claim or a circumstance. Provide what is known, note what is not, and confirm the notice in writing.
Same day: issue a litigation hold covering the resident record, staffing records for the relevant period, scheduling, training files, the personnel file, incident reports, and any electronic communications or video. Suspend any automatic deletion that touches them.

Within seventy-two hours: pull the policy and answer three questions in writing. What is the abuse sublimit, does it carry its own aggregate, and does the excess follow form over it. Those three answers set the boundaries of everything that follows.
Ongoing: communicate with the family, deliberately and with counsel input. The operators who end up in the worst position are usually the ones who said nothing for weeks.
