Filling last-minute cancellations: a waitlist that texts the next patient

A cancellation the day before is an hour your clinician is paid for and nobody uses. A waitlist turns it into a visit for a patient who wanted to come sooner. That only works if the next patient hears about it within minutes and can say yes in one word, so the list, the order and the texts are worth setting up once.

Who goes on the list

Ask at booking, whenever the first time you can offer is later than the patient hoped. Our recommendation is to record five things:

• whether they want a text when an earlier time opens, yes or no;
• the mobile number to text, which should be the one they gave you;
• the days and times they could come;
• the shortest notice they can manage: the same morning, the same day, or a day ahead;
• which clinician they need, or whether anyone will do.

Keep the appointment they already hold. The waitlist only moves them earlier, so nobody loses a booked time by joining it.

One at a time, or everyone at once

There are two ways to offer an opening. Texting everyone who fits fills it fastest, but only one patient can have it. Everyone else who replies gets a second text saying it has gone, and after a few of those, patients stop replying. Offering it to one patient at a time is slower, but every YES gets the time.

Our recommendation is one at a time, in the order patients joined the list, with a reply window that depends on how soon the opening is:

If nobody says yes in time, offer it to the next patient. When a patient takes an earlier time, their old appointment opens in turn, and it goes to the list too. Our recommendation is also to send any patient at most one offer a day, so the list never feels like a stream of messages.

What HIPAA and the FCC's rules ask

The patient's yes

The FCC said in 2015 that a patient who gives a phone number to a healthcare provider has given prior express consent to healthcare calls from that provider, within the scope of the consent and unless the patient says otherwise.³ Its rules also exempt some free healthcare texts to mobile numbers, but the purposes listed are appointment and exam confirmations and reminders, wellness checkups, pre-registration and pre-operative instructions, lab results, post-discharge follow-up, prescription notices and home healthcare instructions.⁴ An offer of a new time is not on that list.

That is why the yes at booking matters. Our recommendation is to treat the waitlist as resting on the patient's own request to hear about earlier times, recorded with the date they asked. Write the texts to the healthcare rule's limits anyway: 160 characters or fewer, your practice's name and contact details, and a STOP reply that you honor at once.⁴ A patient can also withdraw consent with words like "stop", "quit", "cancel" or "unsubscribe", and the rules give you at most ten business days to honor it.⁴ This is a summary, not legal advice.

What the text may say

HHS says practices may contact patients about appointments and leave messages, as long as they limit what a message reveals, for example to the practice's name and number and what is needed to confirm the appointment.¹ An offer needs no more: the time, your name and how to reply. Leave out what the visit is for, and the clinician's name if it gives away the specialty.

HIPAA's definition of marketing leaves out communications for the treatment of a patient by a health care provider, as long as the practice is not paid by a third party to send them.² An earlier time for the patient's own appointment is that kind of message. Keep anything about other services or payment out of it.

Texts you can copy

Each text below stays under 160 characters with a practice name of about 20 characters and a full phone number. Count yours after filling in the brackets.

The booked and too-late texts answer the patient's own message, so they never arrive out of the blue. A patient who takes the earlier time still gets your usual day-before reminder.

What can run by itself

• The list, kept inside your scheduler with each patient's yes, days, times, notice and clinician, so nobody keeps it on paper.
• The match: when a cancellation is recorded, the first patient on the list whose days, notice and clinician fit gets the offer.
• The reply window: if no YES arrives in time, the next patient gets the offer, and the front desk sees each step.
• The booking: a YES books the new time, releases the old one and offers that in turn.
• Opt-outs: a STOP takes the patient off the list the moment it arrives.

The same scheduler can run the other front-desk jobs, which are in our front-desk automation guide.

What stays with your team

• Who goes first when care is urgent. A clinician can move a patient up the list, and that is a clinical decision, not a rule in the scheduler.
• Patients who call instead. A patient who phones about an offer is answered by a person, and the list is updated by hand.
• The patient who cancelled. Whether a late cancellation is charged is set by your policy, as in our late-cancellation policy for therapists and our no-show policy article.

Most waitlist problems start with a number nobody checked, which is why the questions in our new-patient intake checklist include the mobile number and whether texts are fine. More of what we write for practices is on the blog.
