The DoD Military Health System includes hundreds of hospitals and clinics called military
                  treatment facilities (MTF). MTFs provide inpatient and outpatient medical care worldwide
                  to active duty personnel, eligible military retirees, dependent family members, and
                  other eligible individuals.
               
               MTFs currently maintain both paper-based and electronic records for their patients.
                  We have arranged for expedited transfer of most military health system electronic
                  records via the Medical Evidence Gathering and Analysis through Health Information
                  Technology (MEGAHIT) system or the DoD central location system. These processes allow
                  the Disability Determination Services (DDS) to send one request to obtain available
                  MER from all MTFs.
               
               We automatically receive MER from the DoD through MEGAHIT at case transfer from the
                  field office to the DDS in most claims at the initial level. The DDS should first
                  check the folder to see if we already received this evidence electronically through
                  MEGAHIT before requesting MER from the DoD.
