There's a Real API Opportunity Hiding Inside 'How Much Will Rehab Cost Me'

I run a directory site in the addiction treatment space, and the single most common question we get from visitors isn't “which facility is best.” It's “what is this actually going to cost me.” That question sounds simple. In practice it depends on the person's specific insurance plan, their deductible already met for the year, whether the facility is in-network, what level of care they need, and how the plan defines medical necessity for that level of care. None of that is available anywhere in a form a stressed, non-expert person can use in the moment they need it.

The Current State of the Art Is Basically a Guess

We built a simple cost and insurance explainer with a basic calculator so people can plug in some numbers (plan type, whether they've met their deductible, roughly how many days of treatment they expect to need) and get a hypothetical range back. It's genuinely useful as a starting point, and it's better than nothing, which is what most of this category offers today. But I'll be the first to admit what it isn't: it's not connected to any real insurer data. It's a reasonable estimate, not a verified answer. The user still has to call their insurance company, sit on hold, and hope whoever picks up actually knows how to read their own plan's rehab and behavioral health coverage correctly.

That gap, between a rough estimate and a verified, real-time answer, is where I think there's an actual product opportunity, and it's bigger than just addiction treatment.

The Underlying Problem Is Bigger Than One Vertical

Real-time insurance eligibility verification already exists as infrastructure. Clearinghouses and eligibility APIs are used constantly on the provider side: the front desk of a dentist or a surgery center checks real-time benefits before you're even called back. What's missing is a consumer-facing layer on top of that infrastructure, something a person can use directly, before they've committed to a provider or made a phone call, to get an actual answer instead of a hypothetical range. Mental health and behavioral health benefits are notoriously inconsistent and hard to interpret even for the insurers themselves, which makes this exact category (rehab, therapy, psychiatry) one of the highest-anxiety, highest-value places to solve it first.

If someone built a genuinely free or low-cost, API-based, real-time verification tool, even a narrow version scoped to a handful of major insurers and one vertical like behavioral health, directory and provider sites like ours would embed it in a heartbeat. We're not the only ones stuck offering a calculator when what our users actually want is an answer. Any site in healthcare that touches cost transparency has the same problem, because the underlying data is fragmented, gated behind provider-only APIs, and expensive to access at any real volume for a small team.

Why This Is a Good Indie Opportunity, Not Just a Big-Company One

It's tempting to assume this needs a well-funded health-tech startup to pull off, but the eligibility API access itself is more reachable than people think, and a narrow wedge (one vertical, a handful of payers, a clean embeddable widget) is exactly the kind of scoped, unglamorous infrastructure problem indie hackers are good at solving before anyone bigger bothers to. Sites like AddictionRehab.com are a small but real distribution channel for a tool like that, and I'd guess most of the adjacent verticals (mental health directories, urgent care comparison sites, elective procedure cost estimators) are sitting on the same unmet demand. If someone builds the real thing, there's a long list of sites like mine that would happily replace a hypothetical calculator with a real answer.
