ICD-10 Code G47 – Sleep disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47 – Sleep disorders
What it is
G47 identifies disorders that affect normal sleep patterns, including problems with sleep duration, quality, or timing. Use it when the record documents a sleep disorder but does not specify a more exact diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include difficulty falling asleep, staying asleep, excessive daytime sleepiness, or abnormal sleep behavior.
When to use this code
Use G47 when the provider diagnoses a sleep disorder and the chart does not support a more specific code. It may also apply when sleep disturbance is the primary documented problem and no underlying cause is stated. Check documentation for the exact subtype.
Do not use for
Do not use this code for transient poor sleep from a clearly documented temporary cause if another diagnosis better explains it. Do not code from symptoms alone when a more specific sleep disorder is documented.
Coding tip
Query for the specific sleep disorder subtype whenever the note only says “sleep disorder.”
