What a 7 a.m. cancellation actually costs a physio clinic
A cancelled 45-minute visit looks like $120 of lost revenue. Once you count the slot that never refills and the front-desk time spent chasing it, the number is closer to double.
When I ran scheduling for a nine-location physical therapy group, we tracked cancellations as a single number: visits lost per week. It was always somewhere between 30 and 45 across the group, and it always felt like weather. Something that happened to us.
It took me an embarrassingly long time to work out what each one actually cost.
The visit itself
A typical follow-up visit at that group billed around $120 after insurance adjustments. That's the number everybody quotes, and it's the smallest part of the cost.
The slot that doesn't come back
Late cancellations rarely refill on their own. In Corvel's data from clinics before they turn on waitlist fill, only 18% of slots cancelled with less than 24 hours' notice were rebooked by anyone. The other 82% stayed empty. A clinician on salary still works that hour, just without a patient in front of them.
The phone time
Most morning cancellations arrive as a text or a voicemail between 6:30 and 8:00. Someone at the front desk has to read it, find the appointment, cancel it, try to rebook the patient, and then (if they have time) call around to fill the gap. We timed this once. It averaged just over seven minutes per cancellation, and the calls to fill the gap rarely worked because by the time anyone made them it was already 9 a.m.
Adding it up
For a clinic seeing 25 late cancellations a month, the rough maths looks like this:
| Per cancellation | Per month | |
|---|---|---|
| Lost visit revenue | $120 | $3,000 |
| Clinician time with no patient | $55 | $1,375 |
| Front-desk time | $4 | $100 |
| Plan-of-care visits that slip and never happen | ~$60 | ~$1,500 |
| Total | ~$239 | ~$5,975 |
The last row is the one that surprised me. A patient who cancels visit six of a twelve-visit plan and doesn't get rebooked within a week is much less likely to finish the plan. That shows up months later as a discharge that never happened.
What actually helps
Three things moved the number for us, in order of impact:
- Answering the cancellation immediately with a new time. Patients who get a reply with two openings while they're still holding their phone rebook about half the time. Patients who get a call back at 10 a.m. rebook far less.
- Offering the slot to someone who wants it. A waitlist of patients who asked for an earlier visit turns an empty hour into a filled one, if you reach them fast enough.
- Making the policy clear before, not after. The reminder text two days out is where the cancellation policy belongs.
None of this is complicated. It just needs to happen at 7 a.m., which is the problem.
