Appointment Reminder Texts: 14 Templates for Clinics

A medical reminder text names the practice, the day and time, one way to confirm or change the visit, and how to stop texts. It leaves out why the patient is coming. Fourteen texts follow, with the rules that shape them.

Quick answer

1. Practice name first, then day and time, one request and a phone number.
2. End every text with "Reply STOP to opt out."
3. Keep each text within 160 characters, real details filled in.
4. Leave out diagnosis, procedure, test and any specialty that hints at a condition.
5. Decide what staff do with a "C", an "R", a question and a "STOP".

This is not legal advice, and I am not a lawyer; check your consent process with counsel. Timing and no-show counting have their own post; this one covers the words.

What goes into one reminder text?

A text in GSM-7, the basic character set, holds 160 characters (Twilio, checked 2026-10-12). One emoji or curly quote switches the whole message to UCS-2, which holds 70, and a longer message splits into parts (Twilio, checked 2026-10-12). So skip emoji, and paste templates as plain text rather than from a word processor.

Which fourteen texts does a practice need?

Replace each square-bracket placeholder. With a made-up 16-character practice name, a phone number and short links, none passed 160 characters in my count; longer details can.

Around booking

Before the visit

After a reply, or when plans change

Fill in a real cutoff in text 8 or drop that sentence. After a YES to text 10, check the slot is still open. Text 11 skips any fee and text 12 carries no offer, because the FCC conditions exclude billing and advertising content.

What should a reminder text never say?

Never name the diagnosis, procedure, test, medication, or a specialty that gives the condition away: "your oncology follow-up" tells anyone holding the phone too much.

HHS describes the minimum necessary standard as reasonable steps to limit the use or disclosure of protected health information to what the purpose needs (HHS, checked 2026-10-12). It does not apply to disclosures to the patient, but I use it as a design rule: a fact the patient does not need to show up stays out. HHS says reminders are part of treatment and can be sent without authorization (HHS, checked 2026-10-12); HIPAA and text messaging has the wider rules.

In Canada, HIPAA does not apply: patient information falls under PIPEDA or a substantially similar provincial law, such as Ontario's PHIPA (Privacy Commissioner of Canada, checked 2026-10-12).

What do carriers and the FCC say about opt-out and limits?

CTIA, the wireless industry association, says a sender should state in the message how to opt out, use standard "STOP" wording, act on plain replies such as "end", "cancel" or "unsubscribe", and send one final confirmation, then nothing more (CTIA, checked 2026-10-12).

The FCC's 2015 order lets health care providers send automated calls and texts to a patient's cell phone without prior consent, but only for a fixed list of treatment messages (appointment and exam confirmations and reminders, wellness checkups, pre-registration and pre-operative instructions, lab results, post-discharge follow-up, prescription notifications, home health care instructions) and only if the patient is not charged, not even against plan limits (FCC 15-72, paragraphs 146 to 148, checked 2026-10-12). Each text must go only to the wireless number the patient gave, name the provider with contact details, stay within 160 characters, follow HIPAA privacy rules, carry no marketing, billing or other financial content, and say the patient can reply "STOP". The provider may initiate one message a day and three a week per patient, so no visit gets all fourteen texts, and it must honor a STOP immediately. The FCC's rules now hold the same conditions at 47 CFR 64.1200(a)(9)(iv) (eCFR, checked 2026-10-12); whether to rely on them or on consent is for counsel.

In Canada, CASL section 6(6) drops the consent requirement for a commercial electronic message that solely facilitates, completes or confirms a transaction the recipient previously agreed to, though it still has to name the sender, give contact information and include an unsubscribe mechanism (Justice Laws Website, checked 2026-10-12).

What does the front desk do with each reply?

Write the answers down before the first text goes out.

The FCC's consent rules count a reply of "cancel" as revoking consent to texts (eCFR, 47 CFR 64.1200(a)(10), checked 2026-10-12), hence C and R in the templates. Neither STOP nor CANCEL means the patient is not coming, so call before the visit.

How do you know the replies are working?

Count them for a week. Illustrative: every number below is made up for an imaginary primary care clinic, and none comes from a client.

The answer rate is (C + R + STOP) ÷ texts sent: 141 ÷ 190 = 74.2 percent. The 49 patients with no reply are the call sheet. The opt-out rate is STOP ÷ texts sent: 3 ÷ 190 = 1.6 percent; watch it after a wording change. The refill rate is slots refilled ÷ R replies, since each R frees a slot: 14 ÷ 24 = 58.3 percent.

If bookings feed Google Ads as conversions, an R logged as a cancellation can retract a booking that later shows up (how to hold those).

What should you ask a text vendor?

• Can I edit every template, opt-out line included, and see the character count?
• Does a C or R reply update the schedule, or does someone retype it?
• Are STOP, END, CANCEL and similar replies handled automatically, with an export of who opted out and when?
• Is there one daily cap across every tool that texts a patient?
• Will you sign a business associate agreement, which HIPAA expects from vendors handling patient information?
