From Our Advocates

We've seen many UnitedHealthcare denials overturned when families work closely with their metabolic specialist to document every vitamin therapy attempt, even those from years ago. One family successfully appealed by including pharmacy records showing B6 prescriptions that didn't lower homocysteine levels, which became crucial evidence for medical necessity.
