My providers will add dx O99.21-0,1,2,3 with the E66.9 for a prenatal visit and usually when the BMI it's more than 30% But there it's no documentation from the provider mentioning spoke with patient about obesity or nutrition or if the obesity it's complicating the Pregnancy, or any other conditions complicated by obesity. I have approached the providers but their answer it's the BMI it's on the note and don't have to add extra add documentation. What should I do as a coder?
