Chignon (from vacuum extraction) due to birth injury

This code describes a localized swelling or hematoma on the scalp of a newborn, specifically resulting from the application of a vacuum extractor during delivery. This chignon is a common, usually benign, birth injury caused by the suction applied to the fetal head.

Use this code when documentation clearly indicates a chignon present on a neonate's scalp and explicitly links its etiology to vacuum extraction during birth. The physician's notes should specify "chignon" or a similar term and mention the use of a vacuum device.

• Differentiate from caput succedaneum (P12.0) and cephalohematoma (P12.3), which have different etiologies and characteristics.
• Ensure the documentation specifies "vacuum extraction" as the cause; otherwise, a more general code for scalp injury might be appropriate.
• This code is for the injury itself; any associated complications or sequelae would require additional codes.
