Is it a rule that all O codes have to have Z3A.-- for weeks of gestation? I have been told this is correct but I do not see it in the Chapter 15 Guidelines. I have a patient in the puerperium who was admitted for anemia within a week after her delivery. So is it correct for me to use O90.81 with Z3A.41 even though she is not actually "gestation" any longer?
Thank you
