Subarachnoid hemorrhage of fetus or newborn

This code signifies bleeding into the subarachnoid space, the area between the arachnoid membrane and the pia mater, occurring in a fetus or a neonate. This intracranial hemorrhage can result from birth trauma, hypoxia, or underlying vascular malformations. It is a serious condition that can lead to neurological complications.

Apply this code when documentation explicitly states a diagnosis of subarachnoid hemorrhage in a liveborn infant or a fetus. This diagnosis is typically confirmed by neuroimaging such as ultrasound, CT, or MRI, and may be associated with signs like seizures, apnea, or altered mental status in the newborn.

• Differentiate from other types of intracranial hemorrhage in the newborn (e.g., intraventricular, subdural) based on precise anatomical location.
• Ensure the documentation specifies "subarachnoid" to avoid miscoding with more general intracranial hemorrhage codes.
• Consider sequencing with codes for underlying causes, such as birth trauma (e.g., 767.0-767.9) or hypoxic-ischemic encephalopathy (e.g., 768.7-768.9), if applicable and supported by documentation.
