Welcome, @dwgksr. You'll notice that I moved your question about Diastasis Recti to this discussion
- Has anyone had effective treatment for Diastasis Recti https://connect.mayoclinic.org/discussion/diastasis-recti/

I did this so you can connect with @sash as well as @lisag03 @rt061069 and @musicbart who have experience with diastasis recti.

The condition isn’t limited to pregnancy. It can affect anyone, including newborn babies and men. In some cases, it can result from lifting heavy weights incorrectly or performing excessive or unsafe abdominal exercises.

I'm sorry to hear that your insurance labels surgery as cosmetic. Have you considered working with a physio therapist to see if targeted exercises may help in your situation?
