The short answer

What is patient texting?

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

From the phone call to the confirmation text

In Settings it is called Patient texting. It is off until the practice turns it on.

1

Lydoh takes the call

A patient asks for an appointment, a refill or a call back. Lydoh writes it up as a request for the front desk.
2

The patient gets a receipt

A couple of minutes after the call, Lydoh texts that the request landed and when the office will follow up, so they don't call again to check.
3

The front desk handles it

Book the slot, send the refill, or make the call, the same as today.
4

Close it, pick what happened

Appointment booked (with the date and time), refill sent, got it, or write your own. The exact text shows before it sends.
5

The patient replies

The reply joins their thread. The office gets an alert that a patient texted, never what they wrote.
6

Reply from the dashboard

Answer in the thread from Messages or from the request itself. Every text with that patient is in one place.

The exact texts

What the patient sees

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."

Appointment booked

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.

Refill sent to pharmacy

Cedar Grove Family Medicine: your prescription request has been sent to your pharmacy. Questions? Reply to this text. Reply STOP to opt out.

Got it, will follow up

Cedar Grove Family Medicine: we got your message and the team will follow up soon. Reply here with any questions. Reply STOP to opt out.

Receipt after a call: appointment

Cedar Grove Family Medicine: we got your appointment request. The front desk will follow up today. Reply here with any questions. Reply STOP to opt out.

Receipt after a call: refill

Cedar Grove Family Medicine: we got your prescription refill request. The care team reviews refill requests within 1 to 2 business days. Reply here with any questions. Reply STOP to opt out.

A reply, and the answer

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.

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

Every text, in one conversation

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.

Appointment confirmations

Texted when the front desk closes a request as booked.

Refill and follow-up confirmations

“Sent to your pharmacy” or “we got your message.”

Lydoh's call receipts

Sent after a call where Lydoh took a request.

Day-before reminders

From appointment reminders, with the patient's C or R reply.

Missed-call text backs

For callers who hung up before leaving anything.

Review requests and replies

If the practice uses them, plus everything the patient writes back.

When a patient replies

An alert with nothing private in it

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

Text anyone who called

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

Is texting patients HIPAA compliant?

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:

Plainly: these are ordinary SMS texts, which are not encrypted end to end. We don't call this secure texting or encrypted texting, and we don't claim a product can make your practice HIPAA compliant. Keep clinical conversations in your patient portal or on the phone.

Carrier registration

Why we ask for your EIN before you text

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).

  1. You enter your details in Settings: legal business name, EIN, business type, address, website, and a contact person carriers can reach. They never contact patients.
  2. Lydoh submits them to The Campaign Registry through Twilio, our phone provider. They are used only for that registration.
  3. Texting starts right away while the carriers review.
  4. If carriers push back, Settings says so, you fix what's off, and submit again.

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

What Lydoh's patient texting does not do

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, answered

What is patient texting?

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.

Can doctors text patients?

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.

Is texting patients HIPAA compliant?

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.

What do Lydoh's patient texts say?

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.

What happens when a patient replies?

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.

Can we text any patient, or send a text blast?

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.

Why does Lydoh need our EIN and business address to turn on texting?

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.

What is A2P 10DLC?

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.

Does patient texting cost extra?

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.

Can we text patients from the Lydoh app?

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.
