Indeed. As you learn medical ninjutsu, you gain knowledge of the chakra, chakra system, and tenketsu throughout the body. While you can't see these minute details without the Byakugan, a medical shinobi is knowledgeable enough to, through the use of Diagnosis, know the location of each person's tenketsu as well as his chakra lines when performing that skill. While closing a tenketsu requires jyuuken mastery, opening one requires either that or medical mastery. Through a medical technique, you can re-open closed tenketsu and chakra lines. In addition to that, the second technique allows you to calm a patient's or teammate's chakra flow by purging malicious chakra or energy from a patients body
