Tentorial tear due to birth injury

This code represents a tear in the tentorium cerebelli, a dural fold separating the cerebrum from the cerebellum, specifically caused by trauma during the birth process. This injury can lead to intracranial hemorrhage and neurological deficits in the neonate.

Use this code when documentation clearly indicates a tentorial tear in a newborn, and the etiology is explicitly attributed to birth injury. Supporting documentation would include physician notes detailing the birth trauma, imaging reports (e.g., MRI, CT scan) confirming the tentorial tear, and neurological assessments of the infant.

• Ensure the documentation specifies "birth injury" as the cause; otherwise, a different code for tentorial tear (e.g., traumatic) may be more appropriate.
• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Look for associated intracranial hemorrhages (e.g., subdural, subarachnoid) that would require additional coding.
