About this chapter
ICD-10-CM Chapter XV — “Pregnancy, childbirth and the puerperium” — spans every category from O00 through O9A. Each category in that range expands into a header code and one or more billable codes with additional specificity (laterality, episode of care, or clinical detail). Open any code’s own page to see its exact position in the hierarchy, its parent and children, and whether it’s billable.
