About Keystone First
Keystone First is a Medical Assistance (Medicaid) managed care health plan that was founded by the Sisters of Mercy in 1982 to help people get care, stay well, and build healthy communities. Today, we remain committed to that mission.
Headquartered in Philadelphia, Keystone First offers all the benefits and services of regular Medical Assistance. We also offer special programs and benefits for our members. We aim to provide a medical home that helps our members access the services they need. And we provide extensive programs to help our members prevent illness and injury so they can live fuller lives.
