Unspecified maternal hypertension, complicating childbirth

This code signifies a diagnosis of hypertension in a pregnant patient that is not further specified as pre-existing, gestational, or pre-eclampsia, and is documented as complicating the process of childbirth (labor and delivery). It indicates that the elevated blood pressure was present during the delivery period and impacted the management or outcome of the birth.

Use this code when the medical record clearly states "maternal hypertension complicating childbirth" without additional detail regarding the type of hypertension. This applies when the provider's documentation explicitly links the hypertension to the delivery event, but does not specify if it was chronic, new onset, or associated with proteinuria.

• Only use this code when the documentation explicitly states "unspecified" or lacks further detail about the type of hypertension.
• Avoid using this code if the documentation specifies gestational hypertension, pre-eclampsia, or chronic hypertension, even if it complicated childbirth.
• Ensure the documentation clearly links the hypertension to the childbirth encounter; do not use for hypertension noted postpartum or antenatally if not complicating the delivery.
