Denied claims,
quietly recovered.

Cajal is an autonomous appeals team for independent clinics. We call the payer, write the letter, and track the outcome, so your staff can stay with patients, not on hold.

Our promise

A clinic shouldn’t lose $38,000 a year because the phone tree is too long.

Every denial is a decision: fight it, or eat the loss. For most independent practices, there isn’t time for either. Cajal removes the choice. We appeal every recoverable claim, automatically.

The landscape

A hidden tax on independent care.

American clinics write off billions every year in denials they had every right to win. Not because the appeals fail, but because no one has the time to send them.

They came back to practicing.

Our billing lead used to spend Thursdays on hold. She now spends Thursdays with patients. I can't overstate what that changed for us.

Cajal knows exactly what payers need to see. Our appeal success rate roughly doubled in the first quarter, and we stopped writing off small claims entirely.
