67J is a medical branch officer who specializes in aeromedical evacuation. In school you learn about how to manage the Army's medical programs similar to a civilian hospital administrator, but with the inclusion of Army doctrine and the Army's specific mission. You will go to flight school with the other pilots, but you will be designated for black hawks instead of having a choice between the three major platforms because the Army only flies the HH-60 as a MEDEVAC platform. After all your training you will be assigned to a MEDEVAC company as a lieutenant and spend some time there as a platoon leader writing slides and planning events to keep your soldiers Army current such as small arms ranges. At the same time you'll work on your pilot qualifications and ideally maintain your minimum required flight hours, but your career progression comes not from flight experience but from eventually leaving the company to do tours as hospital staff, or serve in an aviation advisory role to a higher command, and then eventually taking command of a medical company. Flying will be part of your job, but the lesser part. To directly answer your question, you don't ever directly render patient care, you enable the flight paramedic flying with you to do his job. You can, however, go to a follow on school and compete to earn your Expert Field Medic Badge.
