The waiting room had eleven chairs, and at 9:00 on a Thursday, three of them stayed empty. The nurse practitioner ran twenty minutes behind by 10:00, not because the patients who came were difficult, but because the schedule had been built for eleven people and only eight arrived. The three who did not come had not cancelled. One had a ride that never arrived. One had a ride that arrived an hour late and left without her when she was not at the curb in three minutes. One had simply stopped booking, after two no-shows in a row, because the bus that was supposed to take her took two transfers and a walk she could no longer make.
Multiply that room by every clinic in the country and the number becomes hard to look at. Missed appointments cost the United States health care system an estimated $150 billion a year, according to health care cost data compiled by the Health Management Academy, with the average missed visit worth about $200 in lost revenue — more for specialty, procedural, and imaging slots where staff and equipment sit idle. The average no-show rate across health care settings runs about 23%, according to systematic reviews summarized in 2026 no-show statistics, with primary care near 20% and specialty care near 25%. A single practice running 30 appointments a day at a 20% no-show rate loses roughly $225,000 a year in unrealized revenue on that arithmetic alone.
Transport explains a large share of the loss, and the estimates converge from several directions. About 3.6 million Americans miss or delay medical care each year because they lack transportation, a figure that recurs across federal and industry reporting. Industry analyses put the transport share of missed appointments at 25 to 50% in some summaries and up to 30% in others; one 2026 analysis of the barrier puts the transport-linked share of no-shows near 46%. The spread between those estimates is itself informative: clinics code no-show reasons inconsistently, so the true share is probably understated in the charts that look tidiest. A February 2026 survey commissioned by Uber, of 150 health care professionals, found 57% linking missed visits to transportation barriers, with more than half estimating that 11 to 20% of missed appointments were directly tied to transport, and two-thirds putting the cost of a single missed visit between $101 and $250.
Nowhere is the arithmetic crueler than dialysis. About 433,000 people in the United States receive in-center hemodialysis, according to the National Forum of ESRD Networks, and each one travels three times a week, 52 weeks a year — 156 scheduled rides per patient, on a fixed calendar, with no option to skip. Research summarized for NEMT providers reports that transportation problems account for 81% of missed dialysis treatments in one American Journal of Kidney Diseases analysis, and that missing a session raises a patient's adjusted mortality risk by 68%. A separate study of 44 million hemodialysis treatments put transport-linked missed sessions near 0.9 per patient per year — a national floor, not a ceiling, because the clinics with the worst transport have the worst records. A 2026 study from UC Davis Health, based on 78 interviews with patients and staff at four Northern California clinics, found patients left waiting outside clinics for hours after treatment, dizzy and weak, when rides failed; researcher Na'amah Razon's summary was blunt: when rides are late or unreliable, it directly harms patients' health and puts tremendous pressure on clinic staff. The same study's background figures — 10% of patients missing at least one session a month, 35% missing a treatment every three months — show a system running close to the edge even before a van breaks down.
That is the sales case for routing software, stated without decoration. A broker or clinic that can cut its transport-linked no-shows by a third does not save a third of $200 per visit in the abstract; it recovers real slots, real staff hours, and real downstream costs. Patients who miss care do not vanish. They return sicker, through the emergency department, which is the most expensive door in the building: one 2026 analysis links the transport gap to roughly 5.5 million avoidable emergency visits a year. On the other side of the ledger, the Florida study most often cited in NEMT economics found the state's investment in the benefit returning 1,108% — a figure so large it should be read as a sign of how cheap the benefit is relative to the care it protects, not as a precise forecast for any single program. A study of chronically ill Medicaid beneficiaries put the return at more than $40 million a month per 30,000 beneficiaries when transport kept them in care. The direction is consistent even when the exact multiples are not.
The counterargument deserves weight, because a routing company that oversells will be found out by its first payer audit. Transport is not the whole no-show problem: forgetting is the single most common reason patients miss appointments, and automated reminders alone cut no-shows by 30 to 60%, according to Cochrane Database of Systematic Reviews data. A ride that arrives on time for a patient who forgot, feared the diagnosis, or could not afford the copay still ends in an empty chair. And the provider's side of the ledger is thinner than the clinic's: NEMT providers are generally paid only for loaded miles, so a no-show costs them the run both ways, and fraud controls — GPS verification now required in Texas, Florida, California, New Jersey, and New York — add compliance cost to every trip. A routing platform that promises a clinic it can erase no-shows is selling something no software can deliver.
The honest pitch is narrower, and stronger for it. Routing software cannot make a patient remember, afford, or want an appointment. It can make sure that when the patient is ready, the ride is there, the vehicle fits, the driver knows the door, and the return is already booked before the patient is discharged. In a market losing $150 billion a year to empty chairs, the firm that reliably removes the transport reason from the list — and can prove it, trip by trip, to the payer holding the contract — is not selling convenience. It is selling back the schedule itself.
