ICD-10 Code G47.61 – Periodic Limb Movement Disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.61 – Periodic limb movement disorder
What it is
G47.61 identifies periodic limb movement disorder, a sleep-related condition marked by repetitive limb movements during sleep. Use it when the chart documents this disorder as the diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Typical records describe repeated, involuntary leg movements during sleep, sleep fragmentation, or daytime sleepiness linked to those movements.
When to use this code
Use this code when the provider diagnoses periodic limb movement disorder after evaluating sleep disturbance and periodic movements. You may also use it when polysomnography or specialist notes clearly support the diagnosis. If the record only mentions restless sleep or leg discomfort without the disorder, check documentation.
Do not use for
Do not use it for nonspecific insomnia, restless legs syndrome, or other sleep movement complaints unless periodic limb movement disorder is documented. Check documentation when the cause of sleep disruption is unclear.
Coding tip
Code from the provider’s stated diagnosis, not from symptoms alone, and confirm whether the disorder is separate from restless legs syndrome.
