No-Show Rate Benchmarks by Medical Specialty
Patient no-shows cost the US healthcare system an estimated $150 billion annually. But averages are misleading — no-show rates vary dramatically by specialty, appointment type, payer mix, and reminder strategy. This reference compiles benchmark data across 12 specialties to help healthcare operators understand how their numbers compare and what the financial exposure looks like.
No-show rates by specialty
The following benchmarks are drawn from published studies, CMS data, and operational audits across clinic groups. Rates represent the percentage of scheduled appointments where the patient neither showed up nor cancelled in advance.
| Specialty | Avg No-Show Rate | Range | Notes |
|---|---|---|---|
| Behavioral health / psychiatry | 28–32% | Highest across all specialties; appointment anxiety and stigma are key factors | |
| Primary care | 20–25% | High volume amplifies the financial impact even at moderate rates | |
| Internal medicine | 18–22% | Lower urgency follow-ups skew the rate upward | |
| OB/GYN | 16–21% | Prenatal visit no-shows carry significant clinical risk | |
| Cardiology | 15–19% | Episodic care patterns increase no-show risk | |
| Dermatology | 18–22% | Long wait times correlate with higher rates | |
| Orthopedics | 14–18% | Post-surgical follow-ups tend to have lower rates | |
| Pediatrics | 14–17% | Well-child visits have higher compliance than sick visits | |
| Urology | 16–20% | Varies significantly by payer mix | |
| Gastroenterology | 13–18% | Procedure prep burden affects compliance | |
| Ophthalmology | 12–16% | Among the lowest — high perceived urgency | |
| Oncology | 8–13% | Lowest rates; treatment continuity is well understood by patients |
Financial impact per no-show
The direct revenue loss per no-show depends on your specialty, payer mix, and whether the slot is recovered. The figures below are per-appointment estimates based on typical allowed amounts.
How payer mix affects no-show rates
Medicaid patients no-show at roughly 2–3x the rate of commercially insured patients. This is well-documented and not a reflection of patient motivation — it reflects structural barriers: transportation, work schedule inflexibility, and last-minute competing demands.
| Payer type | Relative no-show rate | Primary driver |
|---|---|---|
| Commercial insurance | 1× (baseline) | Reference group |
| Medicare | 1.2–1.5× | Transportation and mobility barriers |
| Medicaid | 2.0–3.0× | Structural access barriers, competing demands |
| Self-pay / uninsured | 2.5–3.5× | Cost anxiety about balance billing |
What actually reduces no-shows
Reminder effectiveness varies dramatically by channel and timing. The data below reflects meta-analyses across clinic types.
- Automated voice call (48h before): 14–22% reduction in no-show rate
- SMS reminder (24h before): 20–38% reduction — highest ROI per dollar spent
- SMS + voice combination: 28–42% reduction
- Overbooking by 10–15%: recovers slots but increases wait times and staff pressure
- Same-day confirmation call: 18–26% reduction but staff-intensive
- Patient portal reminder: 8–14% reduction, dependent on portal adoption
The highest-impact, lowest-cost intervention is a two-touch reminder: automated SMS at 48 hours and voice call at 24 hours. Organizations deploying this combination consistently reduce no-show rates by 28–38% within 90 days.

An Operational Intelligence Audit maps your actual no-show rate against your exact specialty and payer mix, calculates the precise annual revenue loss, and deploys a targeted recovery strategy — not a generic reminder system.
