Congenital monoplegia

This code signifies a congenital paralysis affecting a single limb, meaning the condition is present at birth. It results in the inability to move or control one arm or one leg due to neurological impairment. This is a permanent, non-progressive motor deficit.

Use this code when documentation clearly states a diagnosis of monoplegia that is congenital in origin. This applies to infants and children diagnosed with paralysis of a single extremity from birth, often due to developmental anomalies of the central nervous system. Supporting documentation would include neurological evaluations, physical therapy assessments, and birth history.

• Distinguish from acquired monoplegia, which would be coded differently based on etiology.
• Ensure documentation specifies "congenital" to justify this code; otherwise, a more general or acquired paralysis code may be appropriate.
• Do not use for transient weakness or paralysis that resolves shortly after birth.
