Is Harmony covered by Tricare?

Because our military post does not have an OB office I am off post as a referral and because I am 41 years old I wanted the genetic testing done, which they offered anyway, so I had my blood draw today for it but nobody could confirm if TRICARE covers the harmony test or not. Can anyone tell me if they've had the Harmony test done and if TRICARE covered the cost of it? Now I'm worried that WE may get a bill later on for it because I don't know if it's covered or not but I'm really hoping it is because being older I do worry about being prepared if there's any issues with the baby.
