Denial backlogs are quietly the largest line item nobody on your team has time to fight.
Every independent practice in PT, OT, chiro, behavioral health and adjacent specialties has somewhere between $85,000 and $340,000 a year in reversible denials sitting in the work queue. Most never gets touched. The appeals process was designed to make you give up — six-page forms, payer portals that time out, deadlines buried on page 90 of a provider manual, codes that need a codebook. The dollar amount on the line is rarely worth the hours it takes to fight it. Multiply that by every claim. The bleed adds up.
Every appeal you don't file is a payment the insurance company keeps.
70% of denials are wrong on the merits. 65% of providers never appeal. The ones who do appeal win 60–80% of contested denials. The math is straightforward: the appeal you skip is the dollar amount they get to keep. The biggest reason it stays unfiled is the time cost on the office manager — the appeal takes longer to write than the patient session it represents.
You paste the EOB. You watch the fields populate. You see a number you didn't know existed.
The contracted rate. The number Anthem agreed in writing to pay you for that exact CPT code, in your exact state, on your exact NPI. Published in their own machine-readable file by federal law since 2022. Most providers have never seen it. Denial OS surfaces it in the same panel as the denial — and writes it into the appeal letter automatically.
The whole product, in one sentence.
Paste your EOB → we extract the denial details and pull your contracted rate from the payer's machine-readable file → we generate a 2–3 page formal appeal that cites the rate and the regulations by name → you fax or portal-submit → we track every deadline and ping you at 14 days, 7 days, and the response deadline → if they stall past the legal cutoff, one click pre-fills the state insurance commissioner complaint.
When the check arrives, you mark it won. The dashboard counter ticks up.
And the next denial in the stack is one click away. We pre-suggest the batch ('You have 3 more Anthem CO-97 denials from the same date — send all 3 in one shot?'). The ROI argument writes itself the first month: one recovered $3K denial pays for fifteen months of the Practice tier. After that it's pure margin recovered out of the queue you weren't going to fight anyway.
"I had a stack of denials I'd been telling myself I'd get to. I wasn't going to. I never did. The first letter took five minutes. I sent it that afternoon. The check came three weeks later. Then I sent thirteen more."
