Denied. Fought back. Won.

These are real outcomes. This could be you.

"My insurer called a life-saving surgery 'elective'. ClaimBack's letter cited MAS Notice 120 and the Integrated Shield Plan guidelines. They reversed it in 12 days."

Rachel T. · SingaporeSGD 18,400

"We spent 90 minutes fighting one dental crown denial. ClaimBack did it in 2 minutes — citing the exact Delta Dental processing policy our team didn't even know existed."

Dr. Katherine S. · Colorado$4,200

"Cigna denied my son's mental health treatment. The appeal letter cited MHPAEA parity violations — something I'd never heard of. Approved in 9 days. I cried."

Maria S. · Texas$8,400

3 minutes. That's all it takes.
