G47.62

What This Code Means

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.

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
