Generate Your Free Appeal Letter →Your insurer has classified your treatment as experimental, investigational, or not yet proven — regardless of what your specialist recommends.
Insurers use internal clinical bulletins to determine which treatments are 'established.' A treatment can be standard of care among specialist physicians yet still be classified as experimental by an insurer — often to avoid paying for newer or expensive therapies.
Submit peer-reviewed clinical trials, NCCN guidelines, or specialty society endorsements showing the treatment is accepted medical practice. For cancer care, oncology guidelines are particularly persuasive in appeals.
