Respiratory and cardiovascular disorders specific to the perinatal period (P19-P29)

ICD-10 codes P19 through P29 cover respiratory and cardiovascular disorders specific to the perinatal period, addressing conditions in newborns related to breathing difficulties, heart problems, and complications occurring around birth.

This range includes metabolic acidemia (P19), which refers to acid-base imbalance in newborns, sometimes called neonatal metabolic acidemia or birth asphyxia with metabolic acidemia. Codes under P22 identify various forms of respiratory distress in newborns such as respiratory distress syndrome and transient tachypnea, often recognized as neonatal respiratory distress. The P23 codes specify congenital pneumonia with various infectious causes like viral or bacterial agents including Chlamydia and group B streptococcus. Neonatal aspiration (P24) covers cases where newborns inhale substances such as meconium, amniotic fluid, or blood, potentially leading to respiratory symptoms. Disorders involving air leaks like interstitial emphysema and pneumothorax are coded under P25. Pulmonary hemorrhage in newborns falls under P26, while P27 deals with chronic respiratory diseases like bronchopulmonary dysplasia. Other respiratory conditions including atelectasis and sleep apnea appear in P28.

The section from P29 includes cardiovascular disorders originating in the perinatal period, such as neonatal cardiac failure, tachycardia, bradycardia, hypertension, and persistent fetal circulation. Some conditions like neonatal cardiac arrest and other complex cardiovascular problems are also detailed here. Using these codes helps accurately capture and classify serious breathing and heart issues that newborns may face immediately after birth, ensuring clear identification for medical care and record-keeping.
