Whether or not your health insurance will cover the costs of your HGH treatments is largely dependent on your particular insurance company and policy. HGH is FDA approved for the treatment of any number of conditions that cause growth hormone deficiency in children.
It is also approved for the treatment of the "muscle wasting" that occurs in HIV aids patients. When HGH therapy is prescribed to you for one of these two purposes, it is a good chance that it will be covered by health insurance.
However, your health insurance may or may not cover your HGH medication if it has been prescribed for adult-onset growth hormone deficiency. That will all depend on your exact diagnosis and your insurance. Even if your insurance does not cover your medication, it may cover other aspects of your HGH therapy, such as lab work and doctor's visits.
Many of the pharmaceutical companies that make HGH therapy drugs offer discount programs for patients with prescriptions for growth hormone therapy who are not insured or whose HGH treatments are not covered by insurance.
