Subcutaneous fat necrosis due to birth injury

This code describes a benign, self-limiting skin condition in newborns characterized by firm, indurated nodules or plaques in the subcutaneous fat. It typically develops in the first few weeks of life and is directly attributable to trauma sustained during the birth process, such as pressure from forceps or prolonged labor.

Use this code when documentation clearly indicates the presence of subcutaneous fat necrosis in a neonate, and the etiology is explicitly linked to a birth injury. This diagnosis is often made clinically based on the characteristic skin lesions and a history of birth trauma.

• Ensure documentation specifies "birth injury" as the cause; otherwise, consider other codes for neonatal subcutaneous fat necrosis of unknown or non-birth injury origin.
• Do not confuse with other neonatal skin lesions like sclerema neonatorum or cellulitis, which have different clinical presentations and etiologies.
• This code is typically a secondary diagnosis, with the primary diagnosis often related to the birth injury itself or the newborn's overall health status.
