Klumpke's paralysis due to birth injury

This code describes Klumpke's paralysis, a specific type of brachial plexus injury affecting the lower nerves (C8-T1) that occurs during the birthing process. It results in weakness or paralysis of the hand and forearm muscles, often accompanied by Horner's syndrome. This condition is a direct consequence of trauma sustained at birth.

Use this code when documentation clearly indicates a diagnosis of Klumpke's paralysis in a neonate, explicitly linking it to a birth injury. Supporting documentation should detail the neurological deficits consistent with lower brachial plexus involvement and confirm the injury occurred during delivery.

• Differentiate from Erb's palsy (upper brachial plexus injury) which has distinct coding.
• Ensure the medical record explicitly states "due to birth injury" or provides clear context of birth-related trauma.
• Consider sequencing with codes for other birth injuries or complications, if applicable.
