The submitted documentation does not support the medical necessity of the requested services. In this case, the patient’s parent reports diagnoses of autism, attention deficit hyperactivity disorder (ADHD), and anxiety. However, the submitted records only documented a diagnosis of ADHD, apart from notes indicating that the patient’s mother reported that the patient had the possibility of an autism diagnosis following a second opinion.
