ICD-10 Code G47.33 – Obstructive Sleep Apnea (Adult) (Pediatric) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.33 – Obstructive sleep apnea (adult) (pediatric)
What it is
G47.33 identifies obstructive sleep apnea in adults or children. It means repeated upper-airway blockage during sleep, causing breathing pauses or reduced airflow.
Clinical signs
Common findings include loud snoring, witnessed apneas, gasping during sleep, and excessive daytime sleepiness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents obstructive sleep apnea, whether newly diagnosed or established. It also fits confirmed OSA noted in sleep study reports, specialist assessments, or problem lists. If the record only mentions suspected sleep apnea, check documentation before coding.
Do not use for
Do not use G47.33 for central sleep apnea, sleep-related hypoventilation, or snoring alone. If the diagnosis is unclear or mixed, check documentation.
Coding tip
Code G47.33 only when obstructive sleep apnea is explicitly documented, and verify whether adult or pediatric context is supported by the record.
