About — ABA Claims

The founding story.

My mom is a clinician. For years she bounced between outsourced billers who didn't return her calls and doing it herself after hours. Claims went out late. Some never got paid at all.

I'm a software and data engineer. So I started helping her — building tools, fixing her workflows, learning Medicare and commercial payers from the inside. After a while we got it under control, and I realized: every small clinician has this exact problem. Different specialty, same pain. The outsourced billers don't care. The do-it-yourself path costs you your evenings and your unpaid claims.

"Clinicians don't need another platform. They need a partner who handles the part they didn't go to school for."

I built ABA Claims for the people I love. The technology I built for my mom — now sharpened for Florida ABA and the 2025 Medicaid managed care transition — runs in the background. A senior biller signs off on every claim. You get your evenings back.

The company is Keystone Health Management LLC. ABA Claims is what we do under it. We're based in Miami and Orlando, women-owned, and we serve Florida ABA clinics today.

We're new — by design

We're hand-picking our first 10 clinics.

If you want client #847 at a national billing company, we're not it. If you want a founding partner who'll answer your call and shape what this company becomes — read on.

Locked rate, 24 months.

Whatever rate you sign at — 6% or 10% — is the rate you keep for two years. Public rates will rise as we add clinics. Founding partners are grandfathered in.

What we believe

Three working principles.

People still check the work.

AI is great at structure. It is not great at judgment. A senior biller signs off on every claim before submission. That's not slow — that's how clean rate stays at 95%+.

ii.

You should know our names.

One ops lead per account. Direct line. No tickets, no portals, no "your case has been escalated." If we owe you an answer, you get one from a person.

iii.

Aligned by design.

We get paid as a percentage of what you collect. When your collections rise, ours do. When they don't, neither do ours. Skin in the game, not retainers.

The team

Small team. Big focus.

A founder who's been doing this for her own family for three years, plus a senior biller and the technology that backs them up. That's it. That's the whole team — by design.
