$262B of denied claims.
Most never get appealed.
The US medical revenue cycle is the single largest, slowest, most fragmented administrative system in the developed world. The practices losing the most money are the ones least equipped to fight back. Practice OS is built to close that gap.

Why now
Three structural shifts unlock this market in 2026.
TiC + HPT data is finally usable.
CMS Transparency-in-Coverage rule (Jul 2022) + Schema 2.0 enforcement (Feb 2026) means every commercial payer publishes negotiated rates as machine-readable JSON. ReimburseOS has parsed all of it. Practices can finally see what every other practice is being paid — for the first time in US healthcare history.
Denial rates keep climbing.
Commercial first-pass denial rates rose from 9.0% (2017) to 11.8% (2024). Payers are running AI scrubbers internally. Practices are not. The asymmetry has never been wider — and it's still getting worse.
LLMs collapsed the cost of appeals.
A legal-grade appeal letter that took a billing specialist 90 minutes now takes Claude 5 minutes at $0.20 of inference cost. The economics that made appealing every claim impossible no longer apply. The market hasn't priced this in yet.
Competitive landscape
Five categories of incumbent. None of them solve the integrated problem.
| Category | Examples | What they do | Where they fail |
|---|---|---|---|
| Legacy clearinghouses | Availity · Change Healthcare · Waystar | EDI plumbing · 837/835 routing · basic edits | No ReimburseOS · no AI · no Denial OS · no Reclaim OS |
| Denial-mgmt point tools | RevCycle · ZirMed · Plutus Health | Workflow queues · denial buckets | Manual letters · no ReimburseOS prediction · no Reclaim OS sweep |
| Rate-transparency apps | Turquoise · Serif · ClearHealthCosts | Consumer-facing rate lookup | Built for patients/employers · no claim integration · no Sentry OS scrubbing |
| All-in-one practice mgmt | Athenahealth · NextGen · eClinicalWorks | EHR + scheduling + basic billing | Conflicts of interest · take % of collections · 2010-era logic |
| Outsourced billing companies | R1 RCM · GeBBS · Ensemble | Human-staffed remote billing teams | 5-10% of collections · misaligned · still manual under the hood |
Practice OS occupies an empty quadrant.
Five integrated modules — ReimburseOS · Sentry OS · Denial OS · Reclaim OS · Leverage OS — operating on full TiC + HPT data · powered by an LLM appeals engine · sold to the practice (not the payer, not the patient, not the employer) · flat per-provider fee. Nobody else has the data backbone or the integrated stack to fight on all five fronts at once.
The moat
Three layers nobody else has stacked.
Layer 1 · Data
Every commercial payer's TiC MRF, parsed and queryable.
26,497 NPIs × 67 CPTs × 30+ payers × 50 states. Schema 2.0 native. Multi-terabyte ingestion pipeline running continuously. The only complete picture of contracted rates in the United States.
Layer 2 · Integration
Five modules that make each other smarter.
Reclaim OS flags an underpayment → Denial OS fights it. Sentry OS catches a code error → ReimburseOS repredicts. Leverage OS pulls underpayment patterns into a leverage memo. No bolt-on can replicate this without owning the whole stack.
Layer 3 · Trust
Built for the independent owner-operator.
Twin Flame Group is owner-operator-aligned by founding principle. We don't take a cut of collections. We don't sell the practice's data back to payers. We don't run upsells. The price is the price. The math compounds for the practice — not for us.
See it walking the pipeline.
A single CPT code traveling all five modules. Synthetic data. Real architecture.
