WAC 182-535A-0050. Orthodontic treatment and orthodontic-related services — Authorization and prior authorization
When the medicaid agency authorizes a limited orthodontic treatment, full orthodontic treatment, or orthodontic-related services for a client, including a client eligible for services under the EPSDT program, that authorization indicates only that the specific service is medically necessary; authorization is not a guarantee of payment. The client must be eligible for the covered service at the time the service is provided.
