This section applies only to a prisoner who is a covered employee under § 9-221 of this title. A prisoner who is permanently partially disabled or temporarily totally disabled shall file a claim with the Commission in accordance with this subtitle. After a prisoner has filed a claim, the Commission shall decide any issue of coverage or compensability. Until the prisoner is discharged by pardon, parole, or expiration of sentence, the Commission may not: hold a hearing on or determine a permanent partial disability or permanent total disability of the prisoner; or make an award to the prisoner. When the prisoner is discharged from a correctional institution, the institution promptly shall notify the Commission of the discharge. Promptly after receiving notice under paragraph (1) of this subsection, the Commission shall schedule a hearing to determine the extent of any permanent partial or permanent total disability of the prisoner as of the date of discharge.
