What This Code Means
G47.62 is the ICD-10-CM diagnosis code for sleep related leg cramps. This condition involves painful muscle contractions in the legs that occur during sleep, causing the person to wake up with sudden leg pain or tightness. These cramps are involuntary muscle spasms that happen specifically during sleep periods. G47.62 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering episodic and paroxysmal disorders (g40-g47).
G47.62 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Verify that the cramps are specifically documented as occurring during sleep; if they occur during waking hours, consider alternative codes like R25.2 for muscle cramps.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G47.62 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify that the cramps are specifically documented as occurring during sleep; if they occur during waking hours, consider alternative codes like R25.2 for muscle cramps
- •Document which leg(s) are affected (unilateral vs bilateral) as this may impact severity assessment and treatment planning, though the base code G47.62 does not differentiate laterality
