Obstructive sleep apnea (adult) (pediatric)

This diagnosis code signifies a chronic sleep disorder characterized by recurrent episodes of upper airway obstruction during sleep, leading to partial or complete cessation of breathing. These events result in disrupted sleep, oxygen desaturation, and often excessive daytime sleepiness. It encompasses both adult and pediatric presentations of the condition.

Assign this code when documentation clearly indicates a diagnosis of obstructive sleep apnea, regardless of the patient's age. Supporting documentation typically includes polysomnography (sleep study) results confirming apneic or hypopneic events, along with clinical symptoms such as snoring, witnessed apneas, and daytime fatigue.

• Do not use this code for obstructive sleep apnea specifically diagnosed in a newborn; refer to the P28.3- category.
• Ensure the medical record specifies "obstructive" sleep apnea to differentiate it from central or mixed sleep apnea.
• Consider coding any associated manifestations or complications, such as hypertension or heart failure, as secondary diagnoses.
