ICD-10 Code G47.63 – Sleep related bruxism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.63 – Sleep related bruxism
What it is
G47.63 identifies sleep related bruxism, a sleep disorder marked by repetitive jaw-muscle activity during sleep. It may involve clenching or grinding of the teeth and can occur with or without obvious tooth wear.
Clinical signs
Common findings include audible tooth grinding reported by a bed partner, jaw soreness on waking, and signs of tooth wear or fracture. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician documents sleep related bruxism as the diagnosis. It fits cases where nighttime grinding or clenching is confirmed, even if the note emphasizes dental damage, jaw discomfort, or sleep-associated jaw activity. Check documentation if the record is unclear.
Do not use for
Do not use this code for awake bruxism or nonspecific jaw pain without a sleep-related diagnosis. If the chart only mentions suspected grinding or unrelated dental wear, verify the provider’s documentation.
Coding tip
Assign G47.63 only when the sleep association is documented; otherwise, query for clarification.
