Revenue Left on the Table: The Care Your Patients Are Already Skipping

If Part 1 of this series was about owning the patient relationship instead of renting it to a vendor, and Part 2 was about making the systems behind it agree so the front door tells the truth, this is where owning it finally pays for itself. Because the most valuable thing a real relationship does under value-based care isn’t brand loyalty. It’s behavior change — getting the patients you’re already financially accountable for to take the care they’d otherwise skip.

Start with the clearest example: the annual wellness visit. For a Medicare population it’s essentially free to the patient, and it isn’t a physical — no bloodwork, no gown, just a structured conversation about the year ahead. In one study of physician-led accountable care organizations, getting one was associated with about 5.7% lower total healthcare costs over the next eleven months — roughly $50 per patient per month — along with markedly higher screening rates for fall risk, depression, and cancer. It’s one of the highest-leverage, lowest-friction touchpoints in preventive care. And a large share of eligible patients still never get one — not because they refuse, but because they don’t know it exists, don’t know the difference between a wellness visit and a physical, or don’t know the difference between their health system and their insurance company at all.

A few years ago, as a graduate capstone, a team I was part of built the business case for a health system to close exactly this gap for a population of around 200,000 Medicare Advantage members. That kind of population is only bigger and more common now: Medicare Advantage covers 55% of all Medicare beneficiaries today — about 35 million people — each one attached to a plan that’s paid, at least in part, for keeping them well. In our model, only a minority were completing an annual wellness visit, and every point of improvement mapped to real reimbursement and real preventive care — the kind of value that, left uncollected, is revenue sitting on the table while patients quietly get sicker. The barrier wasn’t clinical capacity. It was engagement.

You don’t fix an engagement problem with a portal

Here’s the trap. When a health system decides to “engage patients,” it usually reaches for a feature — a portal notification, an app push, a reminder email. But a reminder only works on someone who already understands why the thing matters and already trusts the sender. The patients skipping their wellness visit are, almost by definition, the ones a reminder doesn’t reach. You can’t notify your way into a relationship you don’t have.

What actually moves people is being present in their life before they need care — in plain language, without jargon, and often outside the clinic entirely. The strategy the capstone team landed on wasn’t a better portal. It was a branded community and content hub: health information people would actually use, connected to community partners and the everyday places patients already are, with the wellness visit available to book from inside it. Meet people where they’re comfortable, earn a little trust, remove the small barriers — awareness, fear, cost confusion, not knowing who to call — and the clinical visit becomes the easy next step instead of the cold ask.

“Who” and “what” won’t change behavior. You need “why.”

This is the part most engagement efforts miss. Demographic data tells you who a patient is. Transactional data tells you what they did. Neither tells you why they haven’t booked the visit — and without the why, every message is a guess. The attitudes, beliefs, and motivations underneath the behavior are what let you say the right thing, to the right person, in a way that actually lands. It’s the difference between a system broadcasting reminders and a relationship that knows what a given patient is actually worried about. One produces open rates. The other produces booked appointments.

This is what the relationship is worth

Which brings the series full circle. In Part 1, the risk of renting your patient relationship to a vendor was abstract — a loss of ownership you couldn’t quite put a number on. Here’s a number. Medicare pays roughly $120 to $175 for a single annual wellness visit — before the quality bonuses and accurate risk coding it unlocks — and that’s one visit, for one patient, on one gap. A patient you have a real relationship with is a patient you can move toward the care that keeps them well, and under value-based care that’s the same thing as keeping them profitable. The relationship isn’t a branding nicety you either can or can’t afford. It’s the mechanism that turns “we’re accountable for this population’s health” from a liability into the thing you’re actually paid for.

The wellness visit is just the clearest example. The same logic runs through every gap in care: the screening not scheduled, the chronic condition not managed, the patient who drifts out of network because nothing kept them close. Every one of them is revenue left on the table — and every one of them is closed by a relationship, not a reminder.

That’s what the patient relationship is actually worth. Not loyalty for its own sake — the care your patients would otherwise skip, and the cost of skipping it, on both sides of the ledger.
