ICD-10 Code G47.9 – Sleep disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.9 – Sleep disorder, unspecified
What it is
G47.9 identifies a sleep disorder when the record does not specify a more exact type. Use it for sleep-related problems that are documented but not further defined.
Clinical signs
Clinical features vary; refer to documentation. Commonly, notes describe disturbed sleep, difficulty initiating or maintaining sleep, or nonrestorative sleep without a clearer diagnosis.
When to use this code
Use this code when the provider documents a sleep disorder but does not name insomnia, apnea, circadian rhythm disorder, or another specific condition. It also fits when the chart lacks enough detail for a more precise code. Check documentation before assigning it if the sleep complaint is part of another diagnosed disorder.
Do not use for
Do not use G47.9 when the record supports a specific sleep disorder such as insomnia or sleep apnea. Avoid it for symptoms alone if no sleep disorder diagnosis is documented.
Coding tip
Query for the exact sleep diagnosis whenever the note says only “sleep problems” or “sleep disturbance.”
