G47.52

What This Code Means

A sleep disorder where a person acts out their dreams during REM (rapid eye movement) sleep, often involving sudden movements, talking, or even getting out of bed. This occurs because the normal muscle paralysis that happens during REM sleep is not functioning properly.

Coding Tips

• •Verify documentation specifies REM sleep behavior disorder rather than other parasomnias or sleep-related movement disorders, as the distinction affects code selection
• •Check if the condition is associated with neurodegenerative diseases (Parkinson's, Lewy body dementia) as these may require additional codes for the underlying condition
