About Coda

Built by someone who ran into this problem himself.

Aaron Langman runs Hampstead Health, a GP clinic in Adelaide. Before Coda existed, he was the one watching patients quietly fall out of the system, not because anyone on his team was careless, but because no process built for a busy clinic was ever designed to catch them.

The Problem

Like most clinics, Hampstead had a recall process. Patients were meant to come back for care plan reviews, chronic disease checks, and the follow-ups their care actually needed. But knowing a patient was overdue and making sure they were actually seen turned out to be two very different things. Reception was stretched thin, recall lists grew faster than anyone could work through them, and there was no reliable way to know, week to week, who had genuinely fallen through the cracks.

The Build

So Aaron built Coda, not as a product to sell, but as the system his own clinic needed. Something that would connect to the practice management software already in use, flag every overdue and high-risk patient automatically, follow up without relying on someone remembering to, and hand reception a clear, prioritised list of who still needed a call.

The Result

At Hampstead Health, Aaron’s own clinic, monthly care plan reviews completed went from 485 to 1,042, a 115% increase. Revenue followed a similar pattern. These are the results of one clinic, Aaron’s own, and individual results will vary by clinic size, patient volume, and administrative capacity, but they were enough to convince him this was worth building for other practices too.

The Purpose

That’s why Coda exists beyond Hampstead today: to give every clinic, not just his own, a way to automate the follow-through that’s easy to promise and hard to sustain manually, so practices can capture the care and revenue they’re already entitled to, without adding headcount.

Coda makes clinics more efficient, but that’s not the only reason it matters. Every patient who gets followed up on, even after they’ve forgotten their own appointment, is a patient who didn’t fall through the cracks. That’s the part of the job that doesn’t show up in a revenue report, and it’s the part Aaron cares about most.
