She was ready. Forty-three years old, BMI of 47, type 2 diabetes diagnosed eighteen months ago, and a referral from her PCP who’d finally said the words: “I think it’s time to talk about surgery.”
She came to the initial consult engaged and motivated. She asked good questions. She left with a folder of paperwork and a supervised weight management schedule. She completed month one. She completed month two.
Then she missed her third nutrition visit. Nobody called for eleven days. When the coordinator finally reached out, the patient said she’d “been busy” and would reschedule. She never did. By month four, her chart was inactive.
That patient cost the practice roughly $800 in marketing and staff time to acquire. The surgery she would have had was worth $15,000 to $25,000 in combined professional and facility fees. She didn’t choose a competitor. She didn’t decide against surgery. She just fell through a crack — the same crack that swallows 30 to 50 percent of the bariatric pipeline at most programs in the country.
The pre-op obstacle course
Before a bariatric patient reaches the operating room, they have to clear a series of requirements that most other surgical specialties never deal with. The specifics vary by payer, but the general pattern looks like this:
Three to six months of documented monthly visits with a physician or dietitian. Miss a month, and many insurers reset the clock.
Highest dropout riskBehavioral health assessment screening for eating disorders, untreated mental health conditions, and surgical readiness. Wait times for qualified bariatric psych providers can stretch to six weeks or more.
One or more sessions with a registered dietitian, separate from supervised weight management. Often requires a different provider and a different appointment.
An EKG at minimum, frequently a cardiology consult or stress test. Another referral, another scheduler, another waiting room.
Polysomnography to screen for obstructive sleep apnea. Most patients need this. Scheduling through a sleep lab adds another two to four weeks.
Increasingly standard to screen for hiatal hernia and Barrett’s esophagus. Yet another procedure to schedule, prep for, and recover from.
Each step involves a different provider, a different office, a different phone number, and a different timeline. Every handoff is a point where a motivated patient can quietly disengage — not because they changed their mind, but because the process wore them down and nobody noticed them drifting.
What this actually costs
Take a practice that consults 40 new bariatric patients per month. That’s a strong volume — it means the marketing is working and the demand is there.
If that practice converts 55 percent of consults to surgery — a respectable rate — that’s 22 cases per month. The other 18 patients represent sunk costs: marketing dollars to generate the lead, staff time for the initial consult, insurance verification, and early follow-ups.

At a conservative $800 per patient in acquisition cost, those 18 lost patients represent $14,400 per month in wasted spend. That’s $172,800 per year — before you account for the surgical revenue that walked out the door with them.
If even a third of those patients could be recovered — not through harder selling, but simply through consistent follow-up at the moments they’re most likely to disengage — that’s six additional surgeries per month. At an average combined reimbursement of $18,000 per case, that’s $108,000 in monthly revenue from patients you already paid to acquire.
Most practices don’t track this number. They know patients drop off. They don’t know how many, at which step, or what it’s costing them — because nothing in their current system is designed to surface that information.
The gap isn’t clinical. It’s operational.
The patients who drop out of the pre-op process almost never do so because they’ve decided against surgery. Surveys of bariatric program attrition consistently point to the same culprits: logistical confusion about next steps, long gaps between appointments with no contact from the practice, difficulty scheduling with external providers, and a general sense of being “on their own” during what is already an emotionally complicated decision.
Inside the practice, the root cause is nearly always the same: no unified system for tracking where each patient is in their pre-op journey.
The EHR tracks clinical encounters but isn’t built to monitor insurance milestones or flag patients who are falling behind schedule. The patient coordinator maintains a spreadsheet — or several spreadsheets — that have to be manually updated after every visit, every external clearance, every insurance authorization. Outreach is reactive: someone notices a patient hasn’t been in for a while, and maybe they call. Maybe they don’t. There’s no automated trigger, no escalation protocol, no visibility into who’s on track and who’s quietly slipping away.
The result is a system that depends entirely on individual staff members remembering to check on specific patients at specific intervals. In a busy surgical practice, that’s not a system. It’s a hope.
Closing the gaps
The bariatric programs with the highest consult-to-surgery conversion rates haven’t hired twice as many coordinators. They haven’t added more phone calls to an already overloaded staff. They’ve done something more structural: they’ve replaced the manual tracking patchwork with an operational layer that makes patient attrition visible — and preventable.
Milestone-based tracking
Every patient has a clear map of their required pre-op steps with expected completion dates. The system knows that Patient A needs her psych eval by week 8 and her sleep study by week 12. If either one falls behind schedule, it surfaces — automatically, not when someone happens to check a spreadsheet.
Proactive gap outreach
When a patient misses a supervised weight management appointment or goes more than two weeks without scheduling a required clearance, the system triggers outreach within 48 hours — not three weeks later when the coordinator finally notices. The difference between a 48-hour follow-up and a three-week follow-up is often the difference between a patient who reschedules and a patient who’s gone.
A single longitudinal view
One screen that shows every active pre-op patient, where they are in the process, what’s overdue, and what’s coming next. Not a spreadsheet. Not a stack of charts. A living, filterable view that any team member can pull up in seconds and know exactly where things stand.
None of this requires more staff. It requires better infrastructure. The practices that have built this capability aren’t just retaining more patients — they’re doing it with the same team, running at the same capacity, with significantly less daily operational stress.
