(702) 653-2273   (653-CARE)

The hospital has a centralized telephone appointment system.

Most hospital appointments are scheduled, cancelled and/or verified by calling 653-CARE (2273). This number will activate a voice system, which will direct you to the needed medical section.  In some cases, you will need to dial the clinic directly, so please be prepared to write down the phone number given.  Active-duty and TriCare Prime patients have priority in scheduling appointments.  All other patients may call for a space-available appointment Monday through Friday beginning at 7 a.m.

Acute appointments are available for patients who need to be seen on an urgent, same-day basis but are not considered emergencies.  We prefer active-duty members call for an appointment, as the primary care areas do not offer a group "sick call" style appointment.

Appointments with most subspecialty clinics require a referral.

The Creech Medical Aid Station consists of a small flight medicine, ambulance service, family health team and dental clinic.  CMAS provides routine medical/dental care to the entire base population.  Personnel eligible for medical care must be active duty or on active orders.  To schedule dental appointments at Creech call (702) 404-0991/0992 or contact via our Contact Us page.

For flyers sick call hours for acute illness and Return to Fly Status are:  Monday through Friday 0730-0830 and 1430-1500 only.  Non-Acute and routine medical appointments (including flight physicals) can be made weekdays by calling (702) 404-1126.

For non-flyers sick call hours for acute illness are:  Monday through Friday 0730-0830 and 1430-1500 only.  However, there is no morning sick call on the 1st and 2nd Thursday of the month.  Non-Acute and routine medical appointments can be made weekdays by calling (702) 653-CARE and requesting an appointment at Creech.

After duty-hours, flyers should go to the MOFMC/Nellis emergency room.  The flight surgeon on call will be notified of ER visits by flying personnel.  Should a flyer be seen in any ER or outside of the MOFMC/CMAS, it is their responsibility to notify the flight surgeon at the first Sick Call following the visit.  Flyers may NOT fly until cleared by a flight surgeon after receiving treatment in the ER or from a provider outside the hospital.

Hospital 2nd Floor
(702) 653-2600

General dentistry and selected specialty services are provided for active duty personnel.  Routine appointments are made following an examination to determine the type and extent of care required.  Periodic dental exams and cleanings are coordinated through unit monitors/schedulers.  Members desiring exams or cleanings beyond that offered with the periodic exam may request these services through the clinic.  Any treatment obtained from a civilian dentist, including elective care such as orthodontics, must be paid for by the member and coordinated with the clinic prior to initiating treatment.

Emergency dental care is defined as uncontrolled pain, bleeding, rapid swelling or significant trauma to the oral­facial structures.  Immediate emergency care is available for all beneficiary categories.  Patients wishing to be seen during sick call should call the appointment desk at (702) 653-2600 to schedule an appointment.  Walk-ins are not recommended, as they may have to wait until all scheduled sick call patients are seen.  After duty hours, a dentist and technician are on call for consultation and management of dental emergencies.  Patients must report to the emergency room during these times for initial triage and management by the medical staff.

Family Members and Retired Military Personnel

Family members and retirees receive treatment on a stand-by, space-available basis only (waiting in the clinic until a broken appointment or last­ minute cancellation occurs).  Treatment will be limited to exams, cleanings and other single-procedure visits.  Stand-by, space-­available care has been significantly curtailed by DoD and Air Force policy and is extremely limited.  Care guidelines are available at the clinic reception desk.  Non-active duty members are encouraged to seek care in the private sector.

Active duty members are encouraged to enroll their families in the TriCare Active Duty Family Member Dental Plan to ensure routine and emergency treatment needs are provided through civilian sources.  Enrollment in the dental plan is done through Customer Service at the Military Personnel Flight.

702-653-2340 or 702-653-2344

Emergency services for all ages are available 24 hours a day.  An emergency is defined as an acute illness or injury that may pose a threat to life, limb or eyesight; result in unreasonable pain or suffering; or requires immediate care or attention to ensure the best recovery possible.  When someone develops signs and symptoms of a stroke, heart attack, or other life threatening emergency then 911 should be called, or the person should report immediately to the nearest emergency facility.  If deemed medically appropriate, some patients will be taken to the nearest emergency department, instead of the Mike O'Callaghan Federal Medical Center.

The emergency department does not give medical advice over the phone, and if a person believes there is an emergency then 911 should be called, or they should report to a nearby emergency department.

VA beneficiaries may call the VA 24-hour Nursing Advice line at 1-877-252-4866 or the Call Center at (702) 791-9024 for assistance.

All patients will be assessed (triaged) as soon as possible on arrival to the Emergency Department.  Based on the acuity/severity and type of illness some patients may be seen sooner than others.  If medically appropriate, some patients may be referred for same day appointments to their enrolled primary clinic.  As an affiliated teaching facility of the Uniformed Services University of the Health Sciences, patients may be evaluated by medical students and residents in addition to the emergency department staff providers as well.

Non-beneficiaries will have a medical screening examination performed, and if necessary will be transferred to a civilian facility for further needed care.  After evaluation, if patients need continued inpatient care, they may be admitted.  If there are specific services or specialist care needed that is unavailable at the MOFMC, then patients may be transferred to an appropriate civilian facility for continued care.  The Emergency department staff will make all efforts to provide compassionate, timely care for all patients, regardless of the patient category (e.g. Tricare Prime, Tricare for Life, VA).

Frequently Asked Questions (FAQ)

How do I check the status of my referral?

Internal referrals:
Stop by the Referral Management Center (RMC) front desk once your provider has entered a referral for you and before you depart the clinic.  This will permit the staff of the RMC to ensure the referral is visible to RMC staff and validate the contact information we will use to try to reach you.
  • For an URGENT or ASAP referral, within 3 days call the RMC at (702) 653-2273, Option 2.
  • For a ROUTINE referral, once 10 days have passed, call the RMC at (702) 653-2273, Option 2.
Audiocare is the automated calling system that is programmed to contact patients to schedule in-house referrals.  If the call to you goes to voicemail the automated machine leaves voicemail; to prompt you to call the RMC to schedule the specialty appointment.

External referrals:
If the referral is for a specialty not available at the MOFMC you can follow the status of your authorization on-line at  Using that site you can track not only authorizations but also review the status of your claim(s).

If you are tracking a network authorization please call UnitedHealthcare Military & Veterans at 1-877-988-WEST (1-877-988-9378) for updates on the status of the authorization.
