Traum cerebral edema w LOC of 30 minutes or less, sequela

This code signifies a long-term consequence or late effect stemming from traumatic cerebral edema, where the initial head injury resulted in a brief loss of consciousness (30 minutes or less). It indicates that the patient is now experiencing residual symptoms or conditions directly attributable to that past brain swelling.

Apply this code when a patient presents with ongoing neurological deficits, cognitive impairments, or other chronic issues that are documented as a direct sequela of a previously sustained traumatic cerebral edema with a brief loss of consciousness. The medical record must clearly link the current condition to the past traumatic brain injury and specify the duration of the initial loss of consciousness.

• Always sequence this sequela code after the code for the specific residual condition being treated (e.g., cognitive deficit, epilepsy).
• Ensure documentation explicitly states "sequela" or "late effect" and clearly connects the current symptoms to the past traumatic cerebral edema.
• Distinguish from acute traumatic cerebral edema codes, which are used for the initial injury encounter.
