Dural tear

This code signifies a spontaneous or traumatic breach in the dura mater, the outermost membrane enveloping the brain and spinal cord. It represents a defect in this protective layer, which can lead to cerebrospinal fluid (CSF) leakage.

Apply this code when documentation explicitly states a dural tear, often identified during imaging studies or surgical exploration. This typically occurs following trauma, spinal surgery complications (excluding iatrogenic punctures), or in cases of spontaneous intracranial hypotension.

• Ensure the documentation clearly distinguishes a spontaneous or traumatic tear from an iatrogenic puncture during a procedure, as the latter is excluded.
• Look for associated symptoms like CSF leakage, headache, or neurological deficits that support the diagnosis.
• Do not use this code for dural tears explicitly stated as accidental punctures or lacerations during a medical procedure.
