Insurance not covering Level 2 ultrasound?

Marissa • I have 2 girls, 12& 7 and my rainbow baby boys 5 and 2. 2 mc, 8/14 & 1/15.
Has anyone else has issues with their insurance denying coverage for the level 2 ultrasound, claiming its investigational? I'm hoping to get the doc office to change the code and hopefully it gets covered but wth? Isn't that a standard test now?
