I am not sure about your state but our pediatric dentist told me about a Maryland state policy that I was not aware of. Sedation would fall under medical and not dental coverage if certain criteria was met.
I handle our company benefits and wasn't aware of this because we are self insured(our company gets charged for the claim $'s up to a certain stop-loss). The state policy only applied to fully insured companies.
I explained the situation to my boss and they were nice enough to ammend our plan to include it on our medical policy.
It basically states:
Anesthesia and related charges for dental services performed in a
Hospital or Alternate Facility when the dentist and the Physician
determine that such services are necessary for the safe and effective
treatment of a dental condition. Such treatment is limited to a
Covered Person who:
Is a child under 7 years of age; or
Is developmentally disabled; or
Has one or more physical or mental conditions that require
admission to a Hospital or Alternate Facility and general
anesthesia for successful dental treatment.
Is an individual for whom a superior result can be expected from
dental care provided under general anesthesia.
Is an emotionally disturbed child 17 years of age or younger with
severe dental problems requiring immediate treatment.
I don't know how old your child is or if it would be helpful to research it a little bit further.
My son is Autistic and needed crowns - poor boy doesn't even eat candy and I guess he just inherited bad teeth
Good luck.
