The medical emergency affecting a leave recipient shall terminate—

At the end of the biweekly pay period in which the leave recipient's employing agency receives written notice from the leave recipient or from a personal representative of the leave recipient that the leave recipient is no longer affected by a medical emergency;

At the end of the biweekly pay period in which the leave recipient's employing agency determines, after written notice from the agency and an opportunity for the leave recipient (or, if appropriate, a personal representative of the leave recipient) to answer orally or in writing, that the leave recipient is no longer affected by a medical emergency; or

At the end of the biweekly pay period in which the leave recipient's employing agency receives notice that the Office of Personnel Management has approved an application for disability retirement for the leave recipient under the Civil Service Retirement System or the Federal Employees' Retirement System.

The leave recipient's employing agency shall continuously monitor the status of the medical emergency affecting the leave recipient to ensure that the leave recipient continues to be affected by a medical emergency.

An agency may deem a medical emergency to continue for the purpose of providing a leave recipient an adequate period of time within which to receive donations of annual leave.
