Ask Nurse Lynn: Growth Hormone for Adults

Question:

Male, 22 years old, unknown subtype

I am again trying to get my son on an adult maintenance dose of growth hormone. He now has only Medicaid insurance. What testing should I expect them to require for prior authorization? Will this testing be appropriate for assessing PWS need for growth hormone administration? Does the brand name matter?

Nurse Lynn’s response:

You can ask your Medicaid plan if they have a “transition from child to adult growth hormone” policy. Sometimes this means they will not make you do a special test before approving the Growth Hormone.

Usually, insurance companies want adults to take a growth hormone stimulation test before they agree to pay for the medicine. But there are some exceptions. For example, if a person already has several hormone problems, like low thyroid, low testosterone, or low female hormones (FSH and LH), and has a low IGF-1 level, some plans will say that is enough proof that growth hormone is needed.

For people with PWS, these tests don’t always work well. That’s because PWS affects the hypothalamus, the part of the brain that controls hormone signals. The tests check how well the pituitary gland makes growth hormone, but they don’t test how well the hypothalamus sends the signal. So, the results can look “normal” even when the person really needs growth hormone.

If your request for growth hormone is denied, we can help by sending a letter of support to your doctor or insurance company. This letter would explain why growth hormone is important for people with PWS and show that your son is being safely monitored.
