KA42.2ICD-11 MMS 2026-01
Chignon due to birth injury
Description
Chignon is a temporary swelling (oedema of the scalp) secondary to the placement of a ventouse suction cup used in assisted vacuum deliveries. It usually disappears after several hours
Coding note from above levels
Conditions arising in the perinatal period, even though death or morbidity occurs later, should, as far as possible, be coded to chapter 19, which takes precedence over chapters containing codes for diseases by their anatomical site. For children less than 28 days old, assume that a reported condition developed in the perinatal period, unless the duration is stated and the onset was after the first completed week of life.
