In which chapter of the ICD-10-CM would you find a classification for conditions primarily affecting pregnancy and childbirth?

The classification for conditions primarily affecting pregnancy and childbirth is found in Chapter 21 of the ICD-10-CM. This chapter specifically addresses codes for complications of pregnancy, childbirth, and the puerperium. It covers a wide range of diagnoses related to prenatal care, labor, delivery, and postpartum complications.

Chapter 21 is integral for accurately documenting maternal health conditions and their implications for both mother and infant during the perinatal period. By utilizing Chapter 21, healthcare providers can ensure proper classification and communication of these specific health issues for appropriate treatment and care planning.

In contrast, the other chapters mentioned do not focus on pregnancy and childbirth. Chapter 11 pertains to diseases of the digestive system, Chapter 19 involves injury, poisoning, and certain other consequences of external causes, and Chapter 20 is reserved for external causes of morbidity. Thus, Chapter 21 is distinctly relevant to the context of pregnancy and childbirth.
