How to Use MyChart to Talk to Your Doctor Online

MyChart is the online patient portal used by many hospitals and doctors' offices in the United States. It is where you can message your doctor with a question, see the results of blood tests, request a prescription refill, book appointments, and read your after-visit summary — all from your phone or computer.

MyChart is made by a company called Epic. But you do not sign up at Epic's website. Instead, your specific clinic or hospital system (like UCLA Health, Cleveland Clinic, or your local hospital) has its own version of MyChart. You sign up through their website. The app on your phone, however, is the same for every system. You search for "MyChart" in the app store, install it, and then pick your healthcare organization from a list.

The first time you sign up, you will need either an activation code from your doctor's office (printed on a recent visit summary or at the front desk) or a way to prove your identity by matching personal information already on file. Once you are in, you can link multiple providers — so if you see a cardiologist at one hospital and a family doctor at another, both may appear in the same MyChart app.

Sending a message to your doctor is one of the most useful features. Instead of waiting on hold, you type your question — "Can I stop taking the aspirin now?" — and the office gets back to you, usually within 1 to 2 business days. For urgent questions, always call the office directly — MyChart messages are not for emergencies.

Lab results show up as soon as they are ready, often before your doctor calls you. Numbers in red mean "out of normal range." That does not always mean something is wrong — some things are flagged that your doctor does not care about. If you see a red number that worries you, send a MyChart message asking what it means rather than searching Google, which can be scary and often wrong.
