The 2009 version of ICD-9-CM 333.99 can be accessed here.

  • A disorder characterized by aching or burning sensations in the lower and rarely the upper extremities that occur prior to sleep or may awaken the patient from sleep. Complying with an irresistible urge to move the affected limbs brings temporary relief. Sleep may become disrupted, resulting in excessive daytime hypersomnolence. This condition may be associated with UREMIA; DIABETES; and rheumatoid arthritis. Restless Legs Syndrome differs from NOCTURNAL MYOCLONUS SYNDROME in that in the latter condition the individual does not report adverse sensory stimuli and it is primarily a sleep-associated movement disorder. (Adams et al., Principles of Neurology, 6th ed, p387; Schweiz Rundsch Med Prax 1997 Apr 30;86(18):732-736)
