How leakage breaks down across 7 specialties

All data points carry superscript citations. Ranges reflect the variance across procedures, payer mixes, and geographic regions within each specialty. Annual leakage is modeled per surgeon (not per practice).

Specialty Cancellation Rate[1] No-Show Rate[1] Avg Revenue / Case[1] Annual Leakage / Surgeon[modeled] Lift Column

[modeled] Annual leakage derived from: cancel_rate × no_show_rate × avg_revenue × 2,500 slots/year × 0.73 unrebooked gap. See methodology below.

Orthopedics

High implant costs and multi-hour OR slots make cancellations especially costly. Cancellation and no-show rates are elevated by case complexity and pre-op clearance requirements.

Podiatry

High device costs per case mean cancellations directly erode contribution margin. No-show rates reflect the patient population complexity — many podiatry patients have comorbid conditions.

ENT

ENT elevated cancellation rates driven by complex pre-operative assessments — sinus and otologic procedures frequently require allergy testing and imaging clearance.

Ophthalmology

Cataract surgery sees particularly high same-day cancellations. No-show rate driven by elderly patient population with transport and escort requirements.

Urology

Dual-leakage profile: cancellation losses from high-acuity surgical cases and significant no-shows from older male patients with comorbidities and transport complexity.

GI

High volume, moderate slot values. No-show rate is primary leakage driver — procedural simplicity creates perception of low stakes among patients.

General Surgery

Widest cancellation rate range — from laparoscopic cholecystectomy to complex hernia repair. No-show rates reflect general-population patient base.

Methodology

Leakage Formula

Annual Leakage / Surgeon = (Cancellation Rate × Slots/Year × Avg Revenue) + (No-Show Rate × Slots/Year × Avg Revenue) + Unrebooked Gap Where: Slots/Year = 5 surgeons × 10 slots/week × 50 weeks = 2,500 Rebook Rate = ~27% nationally (MGMA 2025) Unrebooked Gap = 73% of (Cancellation Rate × Slots/Year × Avg Revenue)

Lift Column

The "Lift Column" shows the potential recovery improvement when a practice deploys all 4 evidence-based levers (waitlist automation, SMS confirmation, post-op check-ins, rapid-fill protocol). A "—" indicates fewer than 3 pilots contributed data for that specialty — the lift estimate is not yet statistically significant. As the pilot network expands, lift estimates will be published for all 7 specialties.

Confidence note: All figures are network-level aggregates. Individual practice results vary based on waitlist depth, specialty mix, payer contracts, and operational readiness. Annual leakage ranges reflect the 10th–90th percentile within each specialty.
