Recall and reactivation for lapsed patients

Most practices treat recall as a software feature. Postcards go out, reminders fire, and nobody checks whether any of it produced a visit.

Meanwhile the list of people who stopped coming grows every month, full of patients who liked you fine and lost the thread after a move, a job change, or one canceled appointment nobody rebooked.

I am not a lawyer and this is not legal advice. Recall messaging sits on top of federal privacy and telephone consent rules and, in some states, stricter ones. Have your attorney read the message and the vendor contract before either goes live.

Who counts as lapsed, and are they all worth chasing?

No. Segment first, because a single message to everyone performs like a single message to everyone.

Four groups are worth separating.

Overdue hygiene. The largest group and the easiest to bring back. They intended to come and life intervened.

Unscheduled treatment. Patients with a diagnosed plan who never booked the work. The highest value group by a distance, and the one most practices never work deliberately.

Insurance lapses. People who left after a job change and assumed you were out of network. If your participation has changed, that is a welcome message rather than a nag, and it is the largest documented barrier in the category. Patient Prism's Dental Patient Access Report, published 2 July 2026, categorized 1,163,398 booking opportunities from 11,552,668 calls across 8,280 locations and found financial barriers behind 34.4% of them, with insurance outweighing price by more than eleven to one. Vendor research from a call intelligence company, cohort skewed toward practices already watching their phones.

Genuinely gone. Moved away, changed practices deliberately, or had a bad experience. Mark them and stop spending on them. A list including people who left angry produces exactly the reviews you do not want.

Sort by value and recency inside each group. A patient with an unscheduled crown from eight months ago outranks a hygiene recall from three years ago.

What can I actually say in the message?

Enough to prompt a call, and nothing about their care.

This is the rule that catches practices out. A text saying "your crown prep is due" or "time for your periodontal maintenance" puts clinical information into an unsecured channel and, in a household with shared phones, in front of people who are not the patient.

Keep the message plain: it has been a while, we would like to get you back on the schedule, here is how to book. Save the specifics for the call or a secure channel.

Then work out who else is holding the list, because this is where recall becomes a compliance problem. Under the HIPAA definitions at 45 CFR section 160.103, any vendor that creates, receives, maintains or transmits protected health information on your behalf is a business associate needing an executed agreement. HHS's published examples include a third party AI chatbot on a patient portal performing appointment scheduling. A recall platform holding patient names, mobile numbers and last visit dates is inside that definition.

The obligation flows to subcontractors and almost nobody checks past the first vendor. The chain has to be unbroken down to the messaging carrier, the email delivery service, the model provider behind any generated text, and whoever stores the logs. Storage alone defeats the conduit exception. A covered entity can also be exposed where it knew, or should have known, of a pattern amounting to a material breach. Your agency is in that chain the moment it can open the recall dashboard.

Ask each in writing: will you sign a business associate agreement, and who are your subcontractors. Send the answers to your attorney.

A message that cannot say anything specific has to earn the response by being easy to act on. That means a booking link, a text back option, and a phone number, not just an instruction to call the office.

What consent does a recall message need?

More care than a vendor default template gives it, and the answer changes depending on what the message says.

The federal rules live at 47 CFR section 64.1200. Two provisions matter to a practice.

The health care carve out. Calls and texts to wireless numbers that include an advertisement or constitute telemarketing normally require prior express written consent. Section 64.1200(a)(2) carves out a call delivering a HIPAA health care message by or on behalf of a covered entity or business associate, which needs only prior express consent. For residential lines, section 64.1200(a)(3)(v) goes further: a health care artificial or prerecorded voice call requires no consent, capped at one call per day per patient and a maximum of three per week.

The moment the message sells something, the carve out is gone. A recall notice is a health care message. The same message with a whitening special attached is telemarketing, and telemarketing to a wireless number needs prior express written consent, which under section 64.1200(f)(9) means a signed agreement with a clear and conspicuous disclosure stating the person is not required to sign as a condition of purchasing anything. Keep transactional and promotional messages on separate consent records.

Whether a plain "we would like to see you back" text is telemarketing is genuinely unsettled. The dual purpose doctrine treats a message mixing marketing and informational content as telemarketing, and most vendor templates sit in the middle without warning you. That is a reason to keep the message purely about scheduling, and to ask counsel rather than your software provider.

Revocation is the part that gets practices sued, and it got stricter on 11 April 2025. Consent may be revoked by any reasonable method clearly expressing a desire not to receive further messages. Replying stop, quit, end, revoke, opt out, cancel or unsubscribe is per se reasonable, and other words count if a reasonable person would understand them as a revocation, including "take me off your list" and "wrong number." Requests must be honored within a reasonable time not to exceed ten business days, and you may not designate an exclusive means of revoking. One confirmation message is permitted if it contains no marketing.

Three engineering consequences follow and most deployments get all three wrong. An opt out handler cannot regex match only the word STOP. Suppression has to be global across voice and SMS, keyed on the phone number, in one table. And ten business days is a ceiling, not a target.

One case is worth knowing before you sign the vendor contract. In Gaines v. LPC Survival, Ltd., decided in the Central District of California on 16 June 2026, the plaintiff sued the small business, not the SMS vendor, for continuing to text after a stop request. The business tried to bring the vendor in and the court dismissed the vendor on jurisdictional grounds, because the vendor's agreement required litigation in Utah. Your vendor's terms of service are a liability shifting instrument. Have your attorney read them.

What cadence actually brings people back?

A rolling list worked weekly, with a small number of touches per patient and a real gap between them.

Pick a volume your front desk can handle, twenty or thirty patients a week rather than eight hundred in an afternoon. Batch sends produce a spike of calls nobody can answer, and unanswered calls are the whole failure mode. Practices already lose an unusual share of inbound calls, with 31 of every 100 abandoned before reaching an agent in the Patient Prism cohort, which is the context behind where practices lose patients on the phone.

Three touches across a few weeks, in different channels. Text, then email, then a call from a person for the high value segment. Then stop, and put them back in the pool for six months.

Be careful with the response rates a recall vendor quotes you. Every circulating message to booking conversion figure in this category is vendor published with no independent methodology. One reputation platform markets the claim that 77% of consumers are willing to leave a review if requested against 5% otherwise. Another reports roughly 10% invite to review conversion with case studies spanning 9% to 24%. No disclosed sample, no field date, no method, and it is the same genre of number used to forecast your reactivation results. Ask for the sample and the method, then measure your own.

Decide before you start who answers the calls this generates, and what happens after hours. The difference between AI answering, voicemail, and an answering service is a real comparison rather than a marketing one.

Confirm the destination works first. A campaign pushing people to search your practice name lands on your Google listing, so if that listing is wrong, or suspended and waiting on reinstatement, you are paying to send patients into a dead end.

What does a week of this actually produce?

How do I know whether it worked?

Count appointments kept, not messages sent.

Open rates and delivery rates are vendor metrics. What matters is how many lapsed patients booked, how many showed, and what production came from them, tracked per segment so you learn which list to work next quarter.

Set a floor before you start. If the unscheduled treatment segment produces nothing after two full rounds, the problem is usually treatment presentation rather than the message.

Fold the result into your standing numbers rather than reporting it once, because reactivation is a permanent motion rather than a campaign, and it belongs among the dental marketing metrics worth tracking monthly.

If you have several providers, route returning patients back to the one they saw. Patients return for a person, and a practice with a multi-provider Google Business Profile needs that routing decided before the calls start arriving.

What to do this week

Pull the patients with no visit in eighteen months and split them into the four segments. Delete the genuinely gone, then sort the unscheduled treatment group by value.

Write one generic message with no clinical detail, a booking link, and a phone number. Have your compliance advisor read it.

Ask your messaging vendor three questions in writing: will you sign a business associate agreement, who are your subcontractors, and how does your opt out handler treat a reply that does not say STOP. Send the answers and the contract to your attorney.

Confirm your consent records separate health care messages from promotional ones.

Send to thirty patients from the top of the list. Count calls, bookings and kept appointments, then do thirty more next week.

Questions about your recall messages?

Email me at eric@seod.com with the exact wording of the recall message you send now and how often it goes out. I will send back a version with the clinical detail stripped out, a clearer next step, and a note on which of your four segments it is actually written for, because most recall messages are written for none of them.

I answer these myself. I will not tell you whether your texting setup meets your obligations, because that belongs to your compliance advisor and your attorney, but I can tell you why the message is being ignored.
