CommonHealth
Appeal a denied medical claim — entirely on your iPhone
Insurers deny claims that should be covered, and most people never appeal. CommonHealth reads your denial letter, finds the rule that actually applies, and writes the appeal for you to review and send. Everything happens on your phone — your records never leave it.
How it works
- Photograph your denial letter, your insurance card, and any records that support you.
- Check what it read. Insurer, plan type, what was denied, their stated reason, and your filing deadline — all editable.
- It writes the appeal, citing the specific policy or regulation your plan has to apply.
- A second AI checks the first. An independent model re-reads your documents and flags any statement it cannot trace back to them.
- You review, then send it by mail, fax, or your plan's portal. The app never submits anything for you.
Why it runs on your phone
Appeals contain the most sensitive information you have — diagnoses, medications, your member ID. CommonHealth does all of its reading, writing and checking with AI models that live on your device, so those documents never travel. That is why setup downloads about 5 GB once, and why the app works with no account and no sign-in.
Saved appeals are encrypted on the device, locked behind Face ID, and excluded from iCloud backups. See the Privacy Policy for the complete list of what does and does not leave your phone.
What it will not do
CommonHealth is a drafting tool, not a lawyer and not a doctor. It does not give legal or medical advice, it cannot promise your appeal succeeds, and it will not file anything on your behalf. When it cannot support a claim from your own records, it says so rather than writing it anyway. See the Terms of Service.
Who it is for
Anyone who has received a denial — a prescription refused for "step therapy", an MRI called "not medically necessary", a procedure denied as "experimental". It was built for patients in Louisville and southern Indiana, and it carries the Kentucky, Indiana, Medicare and Medicaid appeal rules alongside the major insurers' own published policies.
