What Is the TRICARE West Nurse Advice Line?
The TRICARE West Nurse Advice Line is a free, 24/7 telephone and virtual service that connects TRICARE beneficiaries with registered nurses for health care guidance. It is officially called the Military Health System (MHS) Nurse Advice Line, or NAL.
The service is not a replacement for emergency care. It is a triage and advice resource. When you call, a registered nurse assesses your symptoms, helps you decide whether to treat at home, visit urgent care, or go to the emergency room, and can help you find a TRICARE-authorized provider or facility. In some cases, the nurse can schedule a same-day or next-day appointment at a military hospital or clinic. The nurse can also provide an online absence excuse or sick slip when medically appropriate, subject to service command requirements.
The MHS Nurse Advice Line is operated by Optum Serve on behalf of the Defense Health Agency. It is available to more than 9 million eligible active duty service members and beneficiaries. Beneficiaries can reach a registered nurse via phone (1-800-TRICARE), web chat, or video conference using the beneficiary portal at MHSNurseAdviceLine.com.
TRICARE West Region and Wyoming: What Changed in 2025
Wyoming is in the TRICARE West Region. On January 1, 2025, the TRICARE West Region contractor changed from Health Net Federal Services (HNFS) to TriWest Healthcare Alliance. The new West Region now covers 26 states, including Wyoming. Six states formerly in the East Region—Arkansas, Illinois, Louisiana, Oklahoma, Texas, and Wisconsin—moved to the West Region on the same date.
What this means for Wyoming beneficiaries: Your regional contractor for claims, referrals, and customer service is now TriWest Healthcare Alliance. For general TRICARE West questions, call 888-TRIWEST (874-9378), available 8 a.m. to 6 p.m. in your time zone (Mountain Time for Wyoming), excluding federal holidays.
However, the Nurse Advice Line phone number did not change. It remains 1-800-TRICARE (1-800-874-2273), option 1, available 24/7.

When to Call the Nurse Advice Line
Call the Nurse Advice Line when you or a family member has a non-emergency health concern and you are unsure where to seek care. The service is designed for situations that are not life-threatening but need professional guidance.
Call the Nurse Advice Line for:
Colds, flu, earaches, sore throats, migraines, fever, or rashes
Minor injuries such as sprains, back pain, minor cuts and burns, or minor broken bones
Questions about whether a symptom requires urgent care or can be treated at home
Help finding a TRICARE-authorized urgent care or emergency facility
Advice on self-care at home
Same-day or next-day appointment scheduling when recommended by a nurse and you are enrolled at a military hospital or clinic
Pediatric health concerns (calls about children are routed to nurses with pediatric training)
Health care advice while traveling
Do NOT call the Nurse Advice Line for:
Life-threatening emergencies. Call 911 or go to the nearest emergency room immediately if you have chest pain, signs of stroke, severe shortness of breath, uncontrolled bleeding, or any condition that threatens life, limb, sight, or safety.
When to Use Urgent Care vs. Emergency Room
| Situation | Where to Go | Call NAL First? |
|---|---|---|
| Life-threatening symptoms (chest pain, stroke signs, severe bleeding) | Emergency Room or call 911 | No — call 911 immediately |
| Severe pain, high fever, possible broken bone, deep cut | Urgent Care | Yes — the NAL can help you find a TRICARE-authorized facility |
| Cold, flu, rash, minor sprain, earache | Urgent Care or PCM | Yes — the NAL can advise on self-care or direct you to the right level of care |
| Routine care, prescription refills, physicals | Primary Care Manager | No — contact your PCM during office hours |
TRICARE defines urgent care as medically necessary treatment for an illness or injury that would not result in further disability or death if not treated immediately but requires professional attention within 24 hours. Emergency care is care for an illness or injury that threatens life, limb, sight, or safety.
How the Nurse Advice Line Works
The Nurse Advice Line uses a triage process. When you call 1-800-TRICARE and select option 1, you are connected to a registered nurse. The nurse asks questions about your symptoms, medical history, and current situation. Based on your answers, the nurse provides a recommendation.
What the nurse can do:
Provide self-care advice. For minor conditions, the nurse may recommend home treatment and tell you what symptoms to watch for.
Direct you to urgent care. If your condition requires prompt attention but is not an emergency, the nurse can help you find a TRICARE-authorized urgent care center.
Recommend emergency care. If the nurse determines your symptoms may be life-threatening, you will be advised to call 911 or go to the nearest emergency room.
Schedule an appointment. If you are enrolled at a military hospital or clinic, the nurse can schedule a same-day or next-day appointment when appropriate.
Provide an absence excuse. When medically appropriate, the nurse can issue an online sick slip, subject to your service command’s requirements.
Coordinate virtual urgent care. In some cases, the nurse may connect you with virtual urgent care services.
After you speak with a nurse, you can view a secure summary of your health care advice at MHSNurseAdviceLine.com.
Eligibility: Who Can Use the Nurse Advice Line in Wyoming?
Most TRICARE beneficiaries in Wyoming can use the Nurse Advice Line. The service is available to active duty service members and their family members, retirees and their family members, National Guard and Reserve members, and surviving spouses and caregivers covered under TRICARE.
You are NOT eligible if you are enrolled in:
US Family Health Plan — This plan has its own nurse advice line.
TRICARE Prime Demo — Beneficiaries in this demonstration program are not eligible for the MHS Nurse Advice Line.
Do Veterans qualify?
Veterans who are TRICARE-eligible (military retirees and their family members) can use the Nurse Advice Line. Veterans who receive care through the VA health care system, rather than TRICARE, should contact their VA facility or the VA’s Nurse Advice Line if available. The MHS Nurse Advice Line is a TRICARE benefit, not a VA benefit.
What Wyoming beneficiaries should do next: If you are unsure whether you qualify, call 1-800-TRICARE (874-2273) and ask. The nurse or customer service representative can confirm your eligibility.
Nurse Advice Line vs. Telemedicine: What’s the Difference?
The Nurse Advice Line and telemedicine are different services. The Nurse Advice Line provides advice and triage — a nurse helps you decide what level of care you need. Telemedicine provides actual medical care — a provider diagnoses and treats your condition via video or phone.
| Feature | Nurse Advice Line | Telemedicine |
|---|---|---|
| What it provides | Health advice, triage, care recommendations | Diagnosis and treatment by a provider |
| Who you talk to | Registered nurse | Physician, nurse practitioner, or physician assistant |
| Cost | Free | Covered under TRICARE with applicable copays |
| Prescriptions | Cannot prescribe | Can prescribe when medically appropriate |
| When to use | You are unsure where to seek care | You know you need medical treatment for a non-emergency condition |
| Access | Phone, web chat, video chat | Phone or video through a telemedicine provider |
TRICARE covers both the MHS Nurse Advice Line and telemedicine services. The Nurse Advice Line is the first call when you need guidance. Telemedicine is the next step when you need treatment.
Referral Rules for Wyoming TRICARE Beneficiaries
Referral requirements vary by TRICARE plan and beneficiary category. Understanding the rules prevents unexpected costs.
TRICARE Prime
Active Duty Service Members (ADSMs): Must have a referral for all urgent and non-emergent civilian services. The Nurse Advice Line can generate an urgent care referral when appropriate to meet this requirement.
Non-Active Duty Prime enrollees: Do not need a referral for urgent care visits, and point-of-service fees do not apply when seeking urgent care from a TRICARE-authorized network or non-network urgent care center or convenience clinic.
Specialty care: Most specialty services require a referral from your primary care manager (PCM).
TRICARE Select
No referral is required for urgent care or specialty care from TRICARE-authorized providers.
Emergency Care
No referral or authorization is required for emergency care. TRICARE Prime and TRICARE Select beneficiaries can go directly to any emergency room or call 911.
What Wyoming beneficiaries should do next: If you are an active duty service member, always call the Nurse Advice Line before seeking urgent care from a civilian provider. The nurse can generate the required referral. If you are a non-active duty Prime enrollee, you can go directly to urgent care without a referral, but calling the NAL first can help you find a TRICARE-authorized facility.
Pediatric and Mental Health Support
The Nurse Advice Line is equipped to handle pediatric and mental health concerns.
Pediatric calls: When you call about a child, you are connected with a nurse who has special training in pediatric care. The nurse can advise on common childhood illnesses and injuries, help you decide whether to seek urgent care, and in some cases, arrange a pediatric video visit at night.
Mental health calls: The Nurse Advice Line is a resource for beneficiaries dealing with stress, depression, anxiety, or thoughts of self-harm. If you are feeling depressed, anxious, or are thinking of harming yourself, the Nurse Advice Line can connect you with appropriate support. The service is available 24/7, including holidays.
If you or someone you know is in immediate crisis, call 988 (Suicide & Crisis Lifeline) or go to the nearest emergency room.
Common Mistakes and How to Avoid Them
1. Calling the Nurse Advice Line for a life-threatening emergency. If you have chest pain, stroke symptoms, severe bleeding, or difficulty breathing, call 911 immediately. Do not wait on the phone with a nurse. The Nurse Advice Line is for non-emergency guidance.
2. Assuming the Nurse Advice Line is the same as your PCM. The Nurse Advice Line provides advice and triage, not ongoing medical care. For routine care, prescription refills, and chronic condition management, contact your primary care manager.
3. Forgetting to notify your PCM after emergency care. If you are enrolled in TRICARE Prime and receive emergency care, contact your PCM within 24 hours or the next business day to coordinate follow-up care and ensure referrals are placed for any specialty care.
4. Not confirming urgent care facility authorization. TRICARE defines “urgent care” differently from emergency care. Before visiting an urgent care center, call the Nurse Advice Line or check the TRICARE West provider directory to confirm the facility is TRICARE-authorized. Using a non-authorized facility can result in denied claims.
5. Assuming all TRICARE plans have the same referral rules. Active duty service members have different referral requirements than non-active duty Prime enrollees and TRICARE Select beneficiaries. Verify your plan’s rules before seeking care.
6. Waiting until after hours to call when the issue could have been handled by your PCM. The Nurse Advice Line is designed for after-hours, weekend, and holiday guidance. If your PCM is available during regular hours, contact them first for non-urgent matters.
