- Request a peer-to-peer review, in which your doctor will speak to a doctor at the insurance company and explain why this type of treatment is medically necessary.
- Parents may consider hiring an advocate or attorney who has experience with health insurance law.
- Don’t give up. As frustrating as a denial may be, it might be overturned as you follow the appeal process.
