Appointments & Referrals

SEPTEMBER 1, 2022 - Appointment Line hours updated

As of September 1, 2022, the Keller Army Community Hospital Appointment Line hours of operation will be 0700 to 1530.

Please utilize TRICARE Online – available 24 hours, 7 days a week – to make, change, or cancel primary care appointments.

Additionally, patients with referrals at Keller should call the appointment line to schedule specialty care appointments. Outgoing calls for referrals will no longer occur.

Help Keller Army Community Hospital reduce, eliminate “No Shows”

Keller Army Community Hospital is asking for your assistance in reducing, and eventually, eliminating “no-shows” – missed appointments.

Did you know that in Fiscal Year 2017 (October 1, 2016 - September 30, 2017), Keller had 3,107 ‘no-shows’? Did you know since, October 1, 2017, Keller has 2,637 ‘no-shows’? At approximately $75 per visit, these ‘no-shows’ resulted in a loss of $233,025 in FY17, and are currently resulting in a loss of $197,775.

There is a saying in the medical community that “an appointment missed by you, is an appointment missed by two” – 1) the appointment missed by the patient, and 2) that missed appointment time that another patient could have had.

We ask that as soon as you realize you will not make your scheduled appointment, please call the Appointment Center at (845) 938-7992 or (800) 552-2907, or by going to, and cancel so we can re-book that slot for another beneficiary needing to be seen.

We THANK YOU, in advance, for your assistance, and for choosing Keller to provide your high-quality, patient-centered medical services.
