Primary mixed sleep apnea of newborn

This code represents a form of sleep apnea in a newborn characterized by a combination of both obstructive and central apnea events. In mixed sleep apnea, the infant experiences episodes where airflow is blocked (obstructive) and episodes where there is a lack of respiratory effort (central) during sleep.

Use this code when documentation clearly indicates a diagnosis of mixed sleep apnea in a newborn, typically confirmed by polysomnography showing both central and obstructive components. This diagnosis often arises from evaluation of infants presenting with apneic spells, bradycardia, or desaturation during sleep.

• Ensure the documentation specifies "mixed" sleep apnea and explicitly states it is in a "newborn" or "infant."
• Differentiate from primary central sleep apnea of newborn (P28.31) and primary obstructive sleep apnea of newborn (P28.32).
• Code any associated symptoms or underlying conditions, such as prematurity, as secondary diagnoses.
