The patients who already trust you, and haven't heard from you.

Why a full schedule hides it

Lapsed patients don’t cancel. They just stop appearing, and new patients fill the gap, so the calendar never looks short. Meanwhile the list of people who used to come in keeps growing in your booking system, untouched.

These are some of the cheapest bookings you can get. They already know you, they’ve already paid out of pocket, and the trust is already there.

What your answers usually mean

If all you have is a rough “haven’t seen them in a while” list, or nothing, you’re treating a monthly GLP-1 patient, a quarterly tox patient and a patient who comes in twice a year the same way. At 90 days, one is badly overdue and the other isn’t due yet.

If what they hear is the promotion that goes to the whole list, or nothing until they come back on their own, most of them won’t. As I cover in The Reactivation Playbook, the most common reason patients go inactive is that they forgot about you. They didn’t leave angry. They left unattended.

What most practices do, and a better routine

Most practices run a reactivation push once a year, when someone remembers, as a single blast.

A better routine:

• Define “lapsed” by treatment cycle. Around 90 days for monthly programs like GLP-1 or hormones, around six months for quarterly aesthetics.
• Flag patients as they cross that line, continuously, instead of letting them drift for a year.
• Run a short sequence rather than one message: a warm text and email, a follow-up two weeks later, a friendly last note, then a personal call from the provider.
• Make the call. It’s the step most practices skip, and it converts best.

One number to check this week

In your booking system, pull patients whose last visit was 6 to 14 months ago. Group them by their last service. You only need counts.

Then ask one question: when did anyone last contact the people on that list, one to one?

Don’t wait on it. In The 2,000 Names You’re Sitting On I note that patients gone 6 to 12 months reactivate at 15% to 20%, and patients gone 18 months or more drop to 5% to 8%.

Napkin math

Lapsed patients × average annual value of a patient when they were active × 10%

The playbook’s four-step sequence typically recovers 10% to 15% of lapsed patients, so 10% is the low end. Practices that send one message and skip the call often see 3% to 5%, so if you won’t make the calls, use that instead. Either way, it’s an estimate from your own list, not a result.
