Congenital nonprogressive ataxia

This code signifies a group of rare, inherited neurological disorders characterized by a lack of muscle coordination (ataxia) that is present from birth or early childhood and does not worsen over time. It results from developmental abnormalities in the cerebellum or its connections, leading to persistent balance and coordination difficulties.

Apply this code when documentation clearly indicates a diagnosis of ataxia that is congenital in origin and explicitly stated as nonprogressive. This typically involves a pediatric patient presenting with early-onset, stable motor incoordination, often accompanied by genetic testing results confirming a specific congenital ataxia syndrome.

• Ensure the documentation explicitly states "congenital" and "nonprogressive" to differentiate from acquired or progressive forms of ataxia.
• Do not use this code for ataxias that are acquired later in life or those that are known to worsen over time.
• Consider additional codes for specific genetic syndromes or associated neurological manifestations, if documented.
