How to Message Your Doctor Through a Patient Portal

How does portal messaging work?

Patient portals are secure, HIPAA-compliant platforms provided by your healthcare system or practice. Once you are logged in, navigate to Messages or Inbox, start a new message, select the recipient — often your specific provider or a general care team inbox — write your question, and send.

Many portals also let you attach files, such as a photo of a rash or a document from another provider. Messages are typically read by clinical staff first; urgent matters may be triaged and forwarded, or you may hear back from a nurse before your doctor responds directly 1Ref 1Huang M, Fan J, Prigge J, Shah ND, Costello BA, Yao L (2022).Characterizing Patient-Clinician Communication in Secure Medical Messages: Retrospective Study.Analysis of 5.65 million secure portal messages at Mayo Clinic; 72.2% of patient messages received a clinical response within 1 day and 90.6% within 3 days; primary care physicians and NPs carry the heaviest per-clinician messaging burden.

The portal appearance and menu labels vary by platform — MyChart, Athenahealth, eClinicalWorks, and others each look a little different, but the general steps are the same. Federal interoperability rules now require most health plans and many providers to support patient access to health information through digital interfaces 2Ref 2Centers for Medicare & Medicaid Services (2020).CMS Interoperability and Patient Access Final Rule (CMS-9115-F).Federal regulation implementing 21st Century Cures Act patient-access provisions; requires health plans and providers to support patient access to health information through digital APIs, underpinning the legal framework for secure patient portal messaging.

What can you send in a portal message — and will you be charged?

Portal messaging is well-suited for:

• Requesting a medication refill or asking a dosing question
• Sharing a brief symptom update on a known, stable condition
• Requesting a referral for a scheduled appointment
• Asking about a test result that appeared in your portal
• Sharing a home reading (blood pressure, blood sugar)
• Requesting a sick or return-to-work note

Message, phone, or visit?

Some messages are billable. Since the 2020 Medicare fee schedule, a clinician may report an online digital evaluation and management code when a patient-initiated message requires their medical decision-making: 99421 for a cumulative 5 to 10 minutes over seven days (approximate Medicare payment $15.50), 99422 for 11 to 20 minutes (about $31), and 99423 for more than 20 minutes (about $50) 3Ref 3FPM Editors (American Academy of Family Physicians) (2020).New codes for responding to portal messages.Physicians or other qualified health professionals who perform digital E/M services for a single patient for a total of 5 to 10 minutes within a seven-day period can report CPT code 99421, which carries an approximate Medicare payment of $15.50 in a nonfacility setting. For 11 to 20 minutes they can report code 99422, which carries an approximate payment of $31, and for more than 20 minutes they can report code 99423, for approximately $50. To bill for these services, the patient must be established (though the problem may be new), the patient must be the one who initiates the services, and the problem must require a physician or other qualified health professional's evaluation, assessment, and management.. Routine refill and scheduling requests are generally not billed, and what you owe depends on your plan — the same variables behind a doctor visit's cost. Ask your practice how it handles this.

What should I not send through the portal?

Portal inboxes are checked during business hours and are not real-time. For anything that is worsening quickly, a new or worrying symptom, or a medication question that cannot wait, call the practice by phone so someone can triage you right away. Many practices have an after-hours nurse line for calls outside of office hours.

Messages sent on Friday afternoon or over the weekend may not be reviewed until Monday. Research at major health systems finds that about 72% of patient messages receive a clinical response within one day, and 90% within three business days 1Ref 1Huang M, Fan J, Prigge J, Shah ND, Costello BA, Yao L (2022).Characterizing Patient-Clinician Communication in Secure Medical Messages: Retrospective Study.Analysis of 5.65 million secure portal messages at Mayo Clinic; 72.2% of patient messages received a clinical response within 1 day and 90.6% within 3 days; primary care physicians and NPs carry the heaviest per-clinician messaging burden — but this varies by practice and message volume.

How do you write a portal message that gets answered fast?

• State the key question in the first sentence. The person reading it should immediately know whether it needs urgent attention.
• Include relevant context: how long a symptom has been going on, relevant numbers (blood pressure, temperature, blood sugar), the name and dose of any medication.
• One issue per message. Multiple separate topics in one message slow down the response.
• Request a callback explicitly. If you need a phone call rather than a written reply, say so at the end of your message and include the best number and time to reach you.

A structure that works — a subject line and four short lines:

• Subject: Refill request — medication name
• What I need: a refill of the medication and strength printed on the bottle
• Context: how many days are left, the date of my last visit, and any new symptoms
• Pharmacy: name, cross street, and phone number

Timing helps too. Inboxes are worked during business hours, so a request sent Friday afternoon or over a holiday weekend usually waits until the next business day — send anything time-sensitive, refills especially, early in the week.

How do I message my care team through Gale?

If you are a Gale patient, your care team inbox is accessible from the Gale portal. Log in and navigate to Messages to reach your provider. For matters that cannot wait for a message response, use the phone number in your appointment confirmation or book a same-day or next-day telehealth visit directly from the portal.
