Transient tachypnea of newborn

This code represents a self-limiting respiratory condition in newborns characterized by rapid breathing shortly after birth. It is caused by delayed clearance of fetal lung fluid, leading to mild respiratory distress. The condition typically resolves within 24-72 hours without significant intervention.

Use this code for newborns presenting with tachypnea, grunting, nasal flaring, or retractions that are transient and resolve spontaneously. Documentation should clearly indicate the onset of respiratory distress shortly after birth and its resolution within a few days, often with a diagnosis of TTN.

• Ensure documentation specifies "transient" and rules out other causes of neonatal respiratory distress.
• Do not use this code if the tachypnea is prolonged or due to another underlying condition like pneumonia or meconium aspiration syndrome.
• Consider sequencing this as a principal diagnosis when it is the primary reason for admission or observation.
