Built for medical practices
Stop phoning patients back just to say it's done. When your front desk closes a request in Lydoh, it can text the patient a confirmation in one click, and every text with that patient stays in one thread the whole team can see and answer.

The short answer
Patient texting is two-way text messaging between a practice and its patients: the office sends a short text, the patient can reply, and staff answer from a shared inbox rather than a personal phone. It replaces the callback whose only job is to say "you're booked" or "your refill went to the pharmacy."
In Lydoh it does four things. The front desk texts a confirmation when it closes a request. Lydoh, the AI receptionist, texts a receipt after a call where it took a request. Every text with a patient sits in one thread, with their replies. And staff can text anyone who called, straight from the Calls tab.
Nearly every patient can be reached this way: Pew Research Center found that 98% of U.S. adults own a cellphone (Pew, 2025).
How it works
In Settings it is called Patient texting. It is off until the practice turns it on.
The exact texts
These are generated by the same code Lydoh sends with. Each opens with the practice name, because patients may not recognize the number, and ends "Reply STOP to opt out."

Could I come at 11 instead?
Yes, 11:00 works. See you then.
The lock-screen rule
Lydoh's wording never names a medication, a test, a symptom or the reason for the visit. "Your prescription request" is as specific as it gets, because whoever glances at the phone reads the text too.
Write my own
Staff can type their own message, up to 220 characters, and the box reminds them to keep health details out of it. Lydoh still adds the practice name and the opt-out line, and shows the finished text before it goes.
One thread per patient
The Messages tab holds one thread per patient, and the same thread shows on the request it belongs to. Whoever picks it up sees what was already said.
When a patient replies
The front desk is told a patient texted, along the lines of "(555) 010-0142 sent a text. Open Messages to reply." The patient's words are never in the alert, so a staff lock screen shows nothing about anyone's health.
From the Calls tab
Every inbound call has a Text button that opens that caller's thread. New message works only for numbers that already called, texted, left a request or are in your contacts. It is a front desk tool, not a way to text strangers.
HIPAA and texting
Texting patients is allowed under HIPAA when the practice uses reasonable safeguards, but no texting product makes it compliant on its own. HHS has not issued a texting-specific rule for patient messages. Its closest guidance is about e-mail: providers may communicate electronically with patients "provided they apply reasonable safeguards," the Privacy Rule "does not prohibit the use of unencrypted e-mail" for treatment-related communications, and safeguards include "limiting the amount or type of information disclosed" (HHS). For phone messages, HHS suggests leaving only the practice's name and number and "other information necessary to confirm an appointment" (HHS FAQ 198).
Both FAQs add the same rule: if a patient reasonably asks to be contacted another way, the practice should accommodate it. The CMS guidance that requires a "HIPAA compliant secure texting platform" is about hospital care teams texting patient information and orders among themselves, not a front desk confirming an appointment (CMS QSO-24-05).
Lydoh is built around those safeguards:
Carrier registration
US carriers require businesses to register before they text customers from an ordinary local number. Lydoh does the registration; you give it the details.
The system is called A2P 10DLC, "the standard that United States telecom carriers have put in place to ensure that SMS traffic to US end users through long code phone numbers is verified and consensual" (Twilio). A business registers a brand and a campaign with The Campaign Registry, where senders "are verified prior to being allowed to send messages" (The Campaign Registry). Unregistered texts don't get through: since September 1, 2023, messages to the US from unregistered 10DLC numbers are blocked (Twilio).
The rules also shape what Lydoh lets you send. The carrier industry's guidelines treat a reply to someone who texted first as conversational, needing no extra permission; appointment reminders as informational, agreed to when the patient gives their number; and promotions as needing written agreement. They ask for standard "STOP" wording and for opt-outs to be honored (CTIA, 2023). That is why Lydoh texts only people who contacted the practice, ends every confirmation with "Reply STOP to opt out." and has no marketing blasts.
The limits
If you need any of these, a dedicated patient engagement platform tied to your EHR is the better fit.
Not in the mobile app yet
Texting patients works in the web dashboard. The iPhone and Android app does not send patient texts yet.
Not a bulk or marketing tool
Staff can text people who already called, texted, left a request or are in your contacts. There are no campaigns or blasts.
Not encrypted messaging
These are ordinary SMS texts. The protection is what they leave out: no medications, tests, symptoms or visit reasons in Lydoh's wording.
Mobile numbers only
Lydoh checks the line type before a text goes out. Landlines are not texted.
Not written back to your EHR
The thread lives in Lydoh. If your chart needs a note, staff add it there as they do today.
Needs your business details first
Texting turns on after the practice submits its carrier registration details in Settings.
Texting is one part of Lydoh for practices. It works alongside appointment reminders the day before, missed-call text back for callers who hang up, and the AI receptionist that answers every call. Need wording for your own texts? See the reminder and confirmation templates.
FAQ
Patient texting is two-way text messaging between a practice and its patients: the office sends a short text, the patient can reply, and staff answer from a shared inbox instead of a personal phone. In Lydoh it is used for confirmations when the front desk closes a request (an appointment booked, a refill sent, a message received), a receipt after Lydoh takes a request on a call, and replies, all in one thread per patient.
Yes. HIPAA does not ban texting patients. HHS guidance on e-mail says providers may communicate electronically with patients if they apply reasonable safeguards, such as limiting the amount or type of information sent, and its guidance on phone messages suggests leaving only what is needed, such as the practice name and what is needed to confirm an appointment. A patient who asks for a different way to be contacted should be accommodated if the request is reasonable.
It can be, but no texting tool is compliant on its own. Ordinary SMS is not encrypted end to end, so the practical safeguards are about content and access: keep health details out of the text, send only to the patient's own number, honor requests for another channel, and have a BAA with any vendor that handles the messages. Lydoh's texts never name a medication, test, symptom or visit reason, staff alerts never include the patient's words, and a BAA is available. We do not call it secure or encrypted texting, because SMS is neither.
Every text opens with the practice name and ends "Reply STOP to opt out." When the front desk closes a request it picks what happened, and the patient gets, for example: "Cedar Grove Family Medicine: your appointment is set for Fri Oct 16 at 10:30 AM. Reply here if you need to change it. Reply STOP to opt out." Staff see the exact text before it sends. They can also write their own, up to 220 characters.
The reply lands in that patient's thread, in the Messages tab and on the request it belongs to, and the front desk gets an alert that says a patient texted and to open Messages. The alert never includes what the patient wrote, so nothing private shows on a lock screen. Staff reply from the dashboard.
No. Staff can text people who have already contacted the practice: someone who called, texted, left a request, or is in the practice's contacts. There is no bulk or marketing sending. That keeps texting inside the kind of conversation carriers treat as expected, and keeps it a front desk tool rather than a promotion channel.
US carriers require every business that texts customers from an ordinary 10-digit number to register first, a system called A2P 10DLC. Registration asks who is sending, including a tax ID such as an EIN, and unregistered texts are blocked. In Settings you enter the legal business name, EIN, business type, address, website and a contact person. Lydoh submits them to The Campaign Registry through Twilio, and texting starts right away while the carriers review.
A2P 10DLC (application-to-person, 10-digit long code) is the US carrier standard for business texting from ordinary local numbers. Businesses register a brand and a campaign that describes what they text, so carriers can verify the sender. Since September 1, 2023, Twilio blocks messages sent to the US from unregistered 10DLC numbers.
It is part of Lydoh Frontdesk, which is a flat $199 a month with every feature included and a 14-day free trial. Texting is off until the practice turns it on in Settings.
Not yet. Patient texting is in the web dashboard today: the Requests, Calls and Messages tabs. The iPhone and Android app still handles everything else, including after-hours requests for the doctor.
