P58.0
ICD-10-CMThis code signifies hyperbilirubinemia in a newborn resulting from the breakdown of extravasated blood, typically from birth trauma such as cephalhematoma or extensive ecchymoses. The increased bilirubin load from reabsorbed hematomas overwhelms the immature liver's conjugating capacity, leading to visible jaundice.
Apply this code when documentation explicitly links neonatal jaundice to significant bruising or hematomas sustained during birth. This diagnosis requires clear evidence of birth trauma leading to blood extravasation and subsequent elevated bilirubin levels.
