Erb's paralysis due to birth injury

This code signifies a specific type of brachial plexus palsy, Erb's palsy, that results from trauma sustained during the birth process. It involves damage to the upper brachial plexus nerves (C5-C6, sometimes C7), leading to weakness or paralysis primarily affecting the shoulder and arm.

Assign this code when documentation clearly indicates a diagnosis of Erb's palsy and explicitly links its etiology to a birth injury. This typically presents as flaccid paralysis of the affected arm, often with an "waiter's tip" posture, identified in a neonate or infant.

• Ensure documentation specifies "Erb's paralysis" and "birth injury" as the cause.
• Do not confuse with other types of brachial plexus birth injuries (e.g., Klumpke's palsy) or non-birth-related brachial plexus injuries.
• Code this as a primary diagnosis when it is the reason for the encounter; consider additional codes for associated symptoms or complications.
