Our clinic sees high risk pregnancies. Our EMR record shows a "problem list" which our MD fills out at the time of the initial OB visit. The problem list will show whether the patient is hypertensive, or advanced maternal age or if the pregnancy is the result of IVF or if the patient conceived using infertility drugs or AI, etc. When coding the initial visit and even for the subsequent OB visits, if the patient warrants a code from teh V23 and from 640-659, shouldn't the V23 codes be coded first? Also, for visits following the initial OB visit, shouldn't coding from the problem list (what we're managing) be coded along with any other dx that might be found on that particular day; or should we be coding for that particular day only? Thanks for the input.
