Restless legs syndrome

This code represents a neurological sensory-motor disorder characterized by an irresistible urge to move the legs, usually accompanied by uncomfortable sensations. These symptoms typically worsen during periods of rest or inactivity, are partially or totally relieved by movement, and are worse in the evening or night. It is a chronic condition that can significantly impact sleep quality and daily functioning.

Use this code when documentation clearly indicates a diagnosis of restless legs syndrome (RLS) based on the established diagnostic criteria. This includes patients presenting with the characteristic urge to move the legs, often with dysesthesias, that is worse at rest, relieved by movement, and worse in the evening. Supporting documentation should detail the patient's symptoms, their impact, and the diagnostic process.

• Ensure the documentation explicitly states "restless legs syndrome" or provides sufficient detail to meet diagnostic criteria.
• Do not confuse with periodic limb movement disorder (PLMD) unless both are diagnosed; PLMD has a separate code.
• Consider co-occurring conditions like iron deficiency, kidney disease, or neuropathy, which may be contributing factors and should be coded separately if documented.
