Primary obstructive sleep apnea of newborn

This code signifies a diagnosis of primary obstructive sleep apnea (OSA) occurring in a newborn. It indicates a condition where the infant experiences repeated episodes of partial or complete upper airway obstruction during sleep, leading to disrupted breathing and oxygen desaturation, without an identifiable underlying cause such as a congenital anomaly or neuromuscular disorder.

Use this code when documentation clearly states a diagnosis of primary obstructive sleep apnea in a newborn. This diagnosis is typically made after polysomnography (sleep study) confirms obstructive events and other potential causes of apnea have been ruled out. Supporting documentation should include findings consistent with OSA and the absence of secondary causes.

• Ensure documentation specifies "primary" obstructive sleep apnea to differentiate from secondary causes.
• Do not use this code if the sleep apnea is due to a congenital anomaly, neuromuscular disorder, or other identifiable underlying condition; instead, code the specific underlying cause.
• Consider sequencing this code as the principal diagnosis if it is the primary reason for the encounter and treatment.
