Our ds and dd have both had neuropsych testing covered by our medical insurance (ds has had two rounds covered); the key was it was not covered under our mental health benefits, but was covered by medical, and to get coverage we needed a referral from our pediatrician. If we'd just been looking for IQ/achievement testing alone that wouldn't have been covered, but we were referred for the evals because our children were showing signs of anxiety and stress and it was suspected that they might have disabilities that were fueling the anxiety etc. DS was diagnosed with a disability which impacts learning, dd was diagnosed with a vision challenge.
Our insurance has denied coverage for things like OT for ds on the grounds it's an educational challenge and should be addressed by the schools. My understanding is we could appeal that decision if we were able to prove a medical cause for the disability, and our neuropsych has suggested in ds' case we might have reason to suspect a medical cause.
The thing that was really helpful for us when we pursued our first neuropsych eval was to ask the neuropsych's office admin person for advice re insurance - they had worked with our insurance company before and knew exactly what we needed to do to have it covered.
