Official Coding Guidelines

Z3A—do not assign for O00-O08, Z33.2, or postpartum conditions

Category Z3A codes should not be assigned for pregnancies with abortive outcomes (categories O00- O08), elective termination of pregnancy (code Z33.2), nor for postpartum conditions, as category Z3A is not applicable to these conditions.
