Is there a way to autopopulate Above and Below BMI CPT codes?

It seems there should be a way to auto populate CPT (and maybe ICD codes as well) from the BMI when vitals are taken.  I’ve built templates for documentation and included the CPT codes for BMI. Tobacco Use and Falls Risk etc, but I’m working alongside EPIC support people (we have different clinics on different EMRs) and EPIC apparently auto populates all of the G and F codes for Medicare, so the providers don’t have to add anything.  If EPIC can do it, then eCW certainly should be able to as well. 
Any ideas are appreciated.
