No-show rateno-shows÷total scheduled appointments× 100
The MGMA aggregate was 6.81% in 2023, up from 5.55% in 2020 — a measurement, not a goal. Under about 5–7% is healthy; across outpatient studies rates run far higher, so compare yourself to your own trend, not to someone else’s setting.
This guide shows how to measure it the right way, what counts as "normal," what no-shows actually cost you (with the honest numbers), and seven evidence-based ways to bring the rate down.
How to calculate your no-show rate
A no-show is the unexpected absence of a patient from a pre-booked appointment — they simply don't arrive and don't cancel in time. The rate is basic arithmetic:
The math is easy. The part that trips practices up is consistency. Before you track anything, make one decision and stick to it: do same-day cancellations count as no-shows? There's no universal rule — but if you change the definition month to month, your trend is noise. Pick one, document it, apply it everywhere.
One clinic-wide number is a start, but the useful insight is in the breakdown. Track your no-show rate by provider, by weekday, and by appointment type — that's where the real pattern hides (Monday mornings, new-patient slots, one provider's panel). A single average hides all of it.
What's a "normal" no-show rate?
Benchmarks vary a lot by setting, but here's the credible picture:
- MGMA's single-specialty aggregate was 6.81% in 2023, against 5.55% in 2020 and 7% pre-pandemic in 2019 — so it returned toward normal rather than deteriorating. I have dropped the "5–7% is well run" line I used to carry here: I cannot source it, and it amounts to calling the national average excellence.
- Across outpatient studies, rates commonly run 12–42%, reaching ~50% in some settings (a 2024 systematic review).
- Dental practices frequently see around 14%, with adolescents higher (~24%).
- Behavioral health sits at the high end of that range.
The takeaway: compare yourself with your own past months, not with a borrowed number. Double digits means real money is walking out the door — and it's fixable.
What no-shows actually cost you
You'll see scary national figures thrown around — "$150 billion a year," "$200 per appointment." Ignore them. Those numbers don't trace to any primary study; they're SEO folklore.
Here's what the peer-reviewed research actually found: one clinic study measured about $92 in lost reimbursement per missed appointment — which, at a 21% no-show rate, added up to roughly $51,000 a year in one adolescent medicine clinic at a children’s hospital, on about 3,600 appointments. And that's just the missed visit — if the patient never rebooks, the real loss is their whole patient lifetime value.
7 evidence-based ways to cut your no-show rate
Not all tactics are equal. These are ordered roughly by how strong the evidence is — start at the top.
Send automated text reminders
Reminders work; the channel matters less than people claim. A randomised trial of 54,066 patients found two reminders beat one, 4.4% against 5.8%. Where texts are said to beat calls, the evidence is thin: the study usually quoted is one orthodontic office, 1,193 appointments, patients choosing their own channel, and the difference was not statistically significant. Two of my own sources here put phone reminders level with or ahead of texts. Text is faster, cheaper, and people actually read it. If you do one thing, do this.
Send two reminders, timed right
One reminder is good; two is better. A 54,000-patient trial found two reminders (about 3 days and 1 day before) cut no-shows to 4.4%, versus 5.8% for a single 3-day reminder. Space them out.
Offer earlier slots automatically when one frees up
Every cancelled slot is recoverable time. UCSF automated the offer of earlier appointments to patients already booked, and those who took one were seen a median of 14 days sooner; the visits carried about $3M in physician fees over nine months, which is gross billing rather than money recovered, since most of those patients would have come anyway. Only 11% of offers were accepted. A true waitlist, filling a gap with someone not yet booked, is the version that adds volume, and it is less studied.
Let patients self-schedule into open slots
When patients book directly into a real open slot online, no-shows drop — one German eye practice saw 1.8% versus 5.9% for offline booking, though patients chose their own channel there, so the authors could not say whether online booking lowers no-shows or reliable patients simply prefer it. The nuance: it helps when they book a real slot, not when it just files a request for staff to triage.
Flag and call your repeat no-show patients
A small share of patients cause most of the misses. Targeted live outreach to high-risk patients is one of the best-supported tactics (a live-call intervention roughly halved no-shows for flagged patients). You can only do this if you can see who they are.
Use fees as a commitment device — not a fix
Honest truth: no-show fees are popular (MGMA found 42% of medical groups charge one, and separately suggests $25–$50 in primary care) but weak on their own. A rigorous trial found no difference in no-shows, and most fines went unpaid. Use a policy to signal that the slot matters — but don't expect it to do the heavy lifting. Reminders and waitlists move the needle more.
Offer telehealth for the visits that fit
For follow-ups and appropriate visit types, telehealth removes the biggest friction — getting there. A 2025 meta-analysis of 45 studies found telehealth had roughly a third lower odds of non-attendance than in-person visits. Read it as a direction, not a size: every included study was observational, so patients chose the mode, and heterogeneity was I² = 99.9%, which is high enough that the pooled figure should not be quoted as a number to expect.
One to use with care: overbooking chronically high-no-show slots is a real operations technique, but the evidence that it helps without hurting wait times is weak. Treat it as an advanced move for specific problem slots, not a default.
You can't cut what you can't see
Every tactic above starts the same way: knowing your number — overall, and by provider, weekday and appointment type. That's how you find the Monday-morning pattern, spot the repeat no-shows worth a call, and prove a reminder change actually worked. No-show rate is just one of the 12 KPIs every medical practice should track — and it rarely moves in isolation from the rest: those empty slots are the same ones dragging down your provider and room utilization.
Most practices can't see it because the data is buried in the scheduling system, never pulled into one view. Put it on a dashboard once, and the leak becomes obvious — and closeable. It is the fastest-moving of the five numbers worth checking every Monday: the interventions are cheap, and they work within weeks.
Frequently asked questions
No-show rate = (no-shows ÷ total scheduled appointments) × 100 over a period. Decide up front whether same-day cancellations count, then apply that definition consistently.
There is no credible universal benchmark. MGMA's single-specialty aggregate was 6.81% in 2023, against 7% pre-pandemic. Outpatient rates vary enormously between settings; ranges quoted in the literature run from a few per cent to nearly half, and the widely repeated 12–42% band is background cited inside a 2024 review, not a finding of it.
The only figure that matters is yours: no-show rate × your average net revenue per visit. One peer-reviewed clinic study measured about $92 in lost reimbursement per missed appointment.
Reminders move the needle most, and a second reminder beats a better-worded first one. No-show fees signal the slot matters but are weak on their own — a rigorous trial found no difference.
