Code Description

ICD-10 G25.81 is a billable code used to indicate a diagnosis of restless legs syndrome.

Key Diagnostic Point:

Restless legs syndrome (RLS) is a neurological disorder characterized by an uncontrollable urge to move the legs, typically in response to uncomfortable sensations. These sensations are often described as creeping, crawling, tingling, or burning and are usually worse during periods of inactivity, particularly in the evening or at night. Patients may experience significant difficulty in falling asleep or staying asleep due to these symptoms, leading to daytime fatigue and impairment in quality of life. RLS can be associated with various conditions, including iron deficiency, chronic kidney disease, and peripheral neuropathy. It is also commonly seen in patients with Parkinson's disease and other extrapyramidal disorders, where dopaminergic medications may exacerbate or alleviate symptoms. The pathophysiology of RLS is not fully understood, but it is believed to involve dysfunction in the brain's dopamine pathways, which are also implicated in movement disorders. Diagnosis is primarily clinical, based on patient history and symptomatology, and may require exclusion of other conditions.
