Surgical no-show cost: lowest rate, highest dollars per slot.
Surgery runs an 8 percent median no-show on consult slots, dropping to 2 to 4 percent on actual surgical dates. But each missed consult is worth $500 to $900, and the downstream OR pipeline cascade can run $4,000 to $30,000 per hour of unfilled OR time. The downstream cost is what matters.

Three slot types, three different no-show rates
Surgical practice scheduling is more layered than primary care. The same patient flows through three distinct slot types, each with its own no-show profile. Lumping them together (as MGMA's headline number does) masks the operational reality.
| Slot type | No-show rate | Slot value | Why the rate differs |
|---|---|---|---|
| New patient consult | 10 to 12% | $500 to $900 | Standard referral pipeline, similar to medical specialty rates. |
| Pre-op consult and clearance | 6 to 9% | $400 to $650 | Patient already committed to surgery, motivated. |
| Surgical date (OR booking) | 2 to 4% | $4,000 to $40,000 | Major event, pre-op done, patient invested. Rare but costly. |
| Post-op follow-up | 10 to 14% | $180 to $350 | Patient feeling better, motivation drops sharply. |

The OR cascade: where surgical no-shows really hurt
A new-patient surgical consult is the gateway to a procedure pipeline. About 35 percent of new surgical consults convert to a procedure within 90 days (FACS practice management benchmarks). For a general surgery practice, expected pipeline value per consult is approximately $2,400 (probability of procedure x average procedure value, weighted). For ortho, neuro, or cardiothoracic the expected pipeline value runs $4,000 to $12,000. A no-showed consult forfeits not just the $700 consult fee but the expected $2,400 to $12,000 in downstream OR revenue.
When the surgical date itself no-shows, the cascade is acute. Take a 90-minute OR block scheduled for a routine laparoscopic cholecystectomy. The OR slot has been pre-planned with anesthesia, OR nurses, scrub tech, implant or device pre-ordered. If the patient no-shows and no add-on case is available, the practice loses approximately $8,000 to $14,000 of OR revenue, but the OR team and the facility still incur cost. Best-case backfill recovers maybe 40 to 60 percent of revenue. Many practices charge a $250 to $500 surgical-cancellation administrative fee documented in pre-op consent paperwork; it is rarely collected from no-show patients but does occasionally recover from late-cancel patients.
The surgical-confirmation cadence that drops no-show to under 2 percent
Surgical practices that successfully run under 2 percent surgical-date no-show share a consistent confirmation cadence. The pattern below is endorsed by the AORN periOperative practice standards and reflected in the leading ambulatory surgery management platforms (Surgical Information Systems, Provation, ezSurgery).
- Day -14: Pre-op packet mailed. Patient instructions, what to expect, fasting protocol, transportation requirement, post-op care plan. Including transportation arrangements is critical because a no-driver problem on the day-of is a common cause of late cancellation.
- Day -10: Pre-op clinic visit. Anesthesia clearance, history and physical, final risk discussion. About 5 to 8 percent of pre-op clinic visits identify a clinical reason to delay surgery; managing this in advance prevents day-of cancellations.
- Day -7: Personal phone call from surgical scheduler. Confirms transportation, fasting comprehension, post-op caregiver arrangement. Personal voice contact at this stage matters more than text.
- Day -2: SMS reminder. With pre-op instructions, fasting reminder, what time and where to arrive.
- Day -1: Voice confirmation. 30-second call to confirm arrival. If unreachable, escalates to the scheduler who attempts alternative contact methods.
This cadence is more intensive than for consult-only practices, but the per-event cost is small compared to the protected OR revenue. Practices that move from a single 48-hour SMS reminder to the full 5-touch cadence typically drop surgical-date no-show from 4 to 5 percent down to 1 to 2 percent, which is worth $200,000 to $500,000 a year for a typical 4-surgeon practice with an attached ASC.
