Do not use the Direct Access Absence Request to submit leave transactions for PHS Officers.
PHS uses an automated system called Commissioned Officer Leave Tracking System (COLTS). Leave maintenance clerks (LMC) need to become registered users of COLTS by completing the User Registration Form and faxing it to the PHS Liaison, Commandant (CG-1122).
More information can be found in COMDTINST 1000.11(series), Administration of Public Health Service (PHS) Officers Detailed to the Coast Guard.
