559th Medical Group at Joint Base San Antonio-Lackland, Texas

The 559th Medical Group delivers primary and operational health care services at seven geographically separated facilities to a diverse population of 150,000 people from the 130-plus units at Joint Base San Antonio-Lackland, Texas. Operating at seven facilities across JBSA, the group provides care to active-duty military members, dependents and civilians, as well as basic military trainees, technical training students, and students from around the world studying at the Defense Language Institute English Language Center and Inter-American Air Forces Academy.

The 559th MDG is home to the largest optometry and public health flight in the Department of Defense; the DOD's first military training consultation service; the first athletic trainer embedded clinic - known as the Versatile Injury Prevention and Embedded Reconditioning clinic in the Air Force; and one of only three en-route patient staging systems in the continental U.S. Recording approximately 185,000 patient encounters each year, the group provides a variety of services including primary health care, optometry, preventive health, public health, bioenvironmental engineering, acute rehabilitation, and aeromedical services.

We're committed to operational readiness, outstanding customer service, and world-class health care delivery for our beneficiaries.

  • You can see how well we're doing.
  • Click on one of the links to learn how we measure our performance.


  • One measure is not an indication of a facility's quality. Sometimes a smaller population can make a measure move pretty drastically from quarter to quarter, so don't be alarmed if you see a dip or a spike.
  • If there is no data included with the description of the measures below, it may be because your facility doesn't offer that particular service or treatment.
  • Some data is reported every month or quarter and some is reported once a year. Occasionally, a measure is no longer used. But we continue to provide the data from past years as a reference.
  • The dates we report data may vary by measure. Measuring quality, safety, access and patient experience requires time to ensure data is valid and accurate.
  • We report some of the measures in Calendar Year (CY) and some measures in Fiscal Year (FY). Calendar years begin on January 1st. Fiscal years begin on October 1st.
  • If you have questions, please contact the Patient Administration office at your military medical treatment facility or a beneficiary counseling and assistance coordinator
