Workers’ compensation — Permanent total disability — Jurisdiction — Judge of compensation claims erred in dismissing claim for permanent total disability benefits based on conclusion that she lacked jurisdiction — JCC had jurisdiction over case when first petition for benefits was filed because employer/carrier did not administratively accept claimant as PTD until a month later — E/c’s voluntary acceptance did not remove matter from JCC’s jurisdiction because JCC retained jurisdiction over costs, and because it was not clear whether claimant received benefits between the time e/c conceded claimant was entitled to such benefits and the date claimant lodged his claim
