Talk with a Registered Nurse anytime, for no cost. You could save yourself time and money by preventing a visit to the emergency room. The U.S. medical system can be hard to navigate – with Primary Care, Urgent Care, Pharmacies, Teladoc, and Emergency Department options, you may not always know where to go or who to see for your immediate concern. Aetna's nurse line is available 24/7 to guide you. If you have questions about a health concern or need guidance on where to go for care, call 1-800-556-1555 and select the option to speak to a nurse. You can also email a nurse within your www.Aetna.com account who can send you links to health information. Nurses reply within 24 hours. Nurses with Aetna's nurse line cannot diagnose, prescribe, or give medical advice.
