Insurance companies deny millions in legitimate behavioral health claims every year
Solo therapists bear the full cost — and most don't have the billing expertise, time, or leverage to recover that revenue fast.

The real problem is turning a rejected claim into recovered revenue.
✗Billing codes are confusing. CO-97 vs. CO-4 vs. OA-23 — each requires a completely different argument.
✗Writing a credible appeal requires knowing MHPAEA, NCCI edits, CPT bundling rules, and payer-specific policies.
✗Billing consultants charge $75–150/hour. Most solo therapists just absorb the loss.
✗SimplePractice and TherapyNotes don't help. They flag the denial and stop there.

Built for therapists who don't have time for billing headaches
We know you're skeptical. Here's what we've thought through.
Designed to keep identifiers out
AppealWin is built around bracketed placeholders so you never need to type a patient's name, DOB, or SSN. The clinical context and letters you create are stored in your account; keep direct identifiers in your own EHR and use placeholders here.
Legally grounded, not generic
Every letter cites real statutes: MHPAEA (29 CFR 2590.712), NCCI edits, and payer-specific appeal policies. Not a template with your name swapped in.
Built for your specific appeal
CO-97 gets a different argument than CO-4. Aetna gets different language than BCBS. The AI reads the code and the context — it doesn't just fill in blanks.
No EHR integration, no risk
No API keys. No EHR connection. No OAuth. You paste a code, you get a letter. Your generated letters are saved to your account so you can edit and track them later.
MHPAEA: your most powerful appeal argument
The Mental Health Parity and Addiction Equity Act requires insurers to apply comparable standards to mental health and medical/surgical benefits. When parity language fits the denial facts, AppealWin prompts you with citations and requests for the payer criteria to review before sending.
Simple pricing that pays for itself
One overturned therapy claim can recover roughly $150–300. AppealWin costs a fraction of that.
