2025 ICD-10-CM code P29.3

Persistent fetal circulation (PFC), also known as persistent pulmonary hypertension of the newborn (PPHN), is a condition in newborns where the circulatory system doesn't transition to normal postnatal function. This results in continued high pressure in the pulmonary artery and right ventricle of the heart, making it harder to pump blood into the lungs.
