MDA has a dedicated medical emergency phone number in Israel, 101. MDA can become an auxiliary arm of the Israel Defense Forces during times of war. In 2022, MDA became academically affiliated with Ben-Gurion University of the Negev. Following the October 7th attacks against Israel, the American Red Cross presented Magen David Adom with the International Humanitarian Service Award stating that the organization "exemplifies and inspires the humanitarian values of human dignity, respect, [and] compassion."
