While your initial consultation will be covered, intramuscular ketamine is not yet FDA approved as a mental health treatment so is not subject to pre-approval by insurance companies. What this means in practice is that insurance will assess post treatment if the treatment will be covered, which in our experience is almost always covered by insurance.
Heading also offers the insurance-covered treatment Spravato, which is the brand name for esketamine, a version of ketamine administered by a nasal spray.
