Two answers that add up to your price
Ask your insurer whether your plan covers weight management medication and what you would pay, and ask the clinic what it charges if the answer is no. Those two answers together are your price.
What to know before you ask
For background, there is an article on weight control and obesity from Cleveland Clinic. The Obesity Action Coalition and the Obesity Medicine Association are two sites you can browse for more.

Who to call and what to ask them
- Call your insurer and ask, in your own words, whether the medication is covered and what you would pay.
- Ask the clinic what it charges if the medication is not covered.
- Ask both for the answer in writing so you can compare.
Confirm every figure with whoever bills you
A quote for weight management medication is easiest to read next to your insurer's answer, and every figure should be confirmed with the people who will bill you.
