ICD-10 Code G47.8 – Other sleep disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.8 – Other sleep disorders
What it is
G47.8 is used for sleep disorders that do not fit a more specific ICD-10 sleep code. It covers other documented sleep-related conditions when the record supports a disorder, but not a named category.
Clinical signs
Clinical features vary; refer to documentation. You may see persistent sleep disturbance, abnormal sleep behavior, or disrupted sleep quality that is not better classified elsewhere.
When to use this code
Use this code when the clinician documents an “other” sleep disorder and no more specific diagnosis is available. It is appropriate when the chart describes a sleep problem but does not support insomnia, apnea, or another defined sleep disorder. Check documentation before assigning it.
Do not use for
Do not use G47.8 if the record supports a more specific sleep disorder code. Avoid it for nonspecific poor sleep without a documented disorder; code the confirmed diagnosis instead.
Coding tip
If the provider writes only “sleep disturbance,” query for a clearer diagnosis before coding G47.8.
