ICD-10 Code G47.62 – Sleep related leg cramps (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G47.62 – Sleep related leg cramps
What it is
G47.62 identifies leg cramps that occur during sleep or on awakening. Use it for involuntary, painful muscle tightening that disrupts rest and is documented as sleep related.
Clinical signs
Typical documentation includes sudden calf or foot pain, visible muscle hardening, and awakening from sleep. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states sleep related leg cramps, nocturnal leg cramps, or similar wording tied to sleep. It may also fit when the provider documents recurrent nighttime cramps causing sleep disturbance. If the note only says “leg pain” or “cramps,” check documentation.
Do not use for
Do not use it for daytime muscle cramps, restless legs syndrome, or leg pain without cramping. If the diagnosis is uncertain or another sleep disorder is documented, check documentation.
Coding tip
Code G47.62 only when the provider links the cramps to sleep; nonspecific cramping should not be assumed to be sleep related.
