Traumatic cerebral edema w LOC of 1-5 hrs 59 min, init

This code signifies a diagnosis of brain swelling resulting from a head injury, specifically when the patient experiences a loss of consciousness lasting between one hour and five hours and fifty-nine minutes. It indicates the initial presentation and treatment of this condition.

Apply this code for patients presenting with acute traumatic cerebral edema following a head injury, where medical records clearly document a period of unconsciousness within the specified duration. Documentation should include the cause of injury, neurological assessment findings, and the exact or estimated duration of unconsciousness.

• Ensure the duration of loss of consciousness is explicitly documented to fall within the 1 hour to 5 hours 59 minutes range.
• This "A" seventh character denotes an initial encounter for active treatment; use subsequent characters for follow-up care.
• Always code the underlying cause of the traumatic injury (e.g., fall, motor vehicle accident) as an external cause code (V00-Y99) in addition to this diagnosis.
