Urgent Care

Urgent Care services treat non-life-threatening health issues that require immediate attention, such as sprains, the flu, colds, and other common illnesses.

If you’re unsure about whether you need urgent care, contact the Military Health System Nurse Advice Line to speak to a registered nurse. Visit for web chat and video chat, or dial 1-800-TRICARE (874-2273).

For urgent care, please contact us during duty hours or call the Nurse Advice Line at 1-800-874-2273, 24 hours a day, 7 days a week. Non-active duty beneficiaries may also visit a TRICARE-authorized Urgent Care Clinic without a referral. Urgent care is care you need for a non-emergency illness or injury, and should be treated within 24 hours.

You typically need urgent care to treat a condition that:

  • Doesn’t threaten life, limb or eyesight
  • Needs attention before it becomes a serious risk to health

Examples may include things like a high fever or sprained ankle.

Emergency Care

If you are experiencing a life-threatening medical situation (including mental health emergencies), call 911 immediately. Emergency care services treat life-threatening medical issues such as threats to your life, limbs, sight, or safety. The 66th Medical Squadron does not offer emergency care.
