The five sister tools

One claim. Five points of leverage.

Each tool answers one part of the cycle. Each ships with its own product page, its own ICP, its own price. Together they close the loop the legacy RCM stack leaves open.

01 · PREDICT

ReimburseOS

Know the rate before you bill.

Real CMS PFS data, payer-by-payer rate intelligence, contracted-rate snapshots. The negotiation room for independent providers.

reimburseos.com → 02 · PREVENT

Sentry OS

Catch the denial before it happens.

Pre-submission scrubbing. Modifier checks, payer-rule mismatches, missing documentation. Stop denials at the source — before the clearinghouse rejects the claim.

sentry-os.netlify.app → 03 · FIGHT

Denial OS

Fight the denial. Get what you're owed.

AI-drafted appeal letters with the contracted-rate paragraph baked in. Win rate ~30% → ~70%. Turns CARC/RARC codes into a fight you actually win.

denial-os.netlify.app → 04 · RECOVER

Reclaim OS

Recover the underpayment.

EOB-by-EOB audit against the contracted rate. Surfaces the silent 7–18% leakage that no clearinghouse flags. Underpayments hunted, demanded, recovered.

reclaim-os.netlify.app → 05 · RENEGOTIATE

Leverage OS

Negotiate like you have the data.

Upload your payer contracts. We compare to every other payer's published rates. The leverage memo writes itself. The next contract gets signed on your terms.

The master engine

Practice OS bundles all five.

Each tool is sharp on its own. Together they form a closed loop. Practice OS is how a practice runs all five at once, on one log-in, with one revenue dashboard.

PRACTICE OS · MASTER ENGINE BUNDLE

One operating system. Every dollar accounted for.

Predict the rate before you bill. Prevent the denial before it ships. Fight the denial when it lands. Recover the underpayment when it slips through. Renegotiate the contract when leverage is on your side. Practice OS runs the full cycle inside one app — the five sister tools as integrated modules, not five separate logins.
