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

This code describes a long-term consequence or late effect of traumatic cerebral edema, specifically when the initial injury involved a loss of consciousness lasting between one hour and five hours and fifty-nine minutes. It indicates that the patient is now experiencing residual symptoms or conditions directly attributable to that past brain injury and its associated edema.

This code is appropriate for encounters where a patient is being treated for a sequela (e.g., cognitive deficits, post-concussive syndrome, persistent headaches, neurological impairments) directly resulting from a previous traumatic cerebral edema. Documentation must clearly link the current condition to the past brain injury and specify the duration of the initial loss of consciousness.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation explicitly states the original injury was traumatic cerebral edema and specifies the duration of loss of consciousness.
• Do not use for acute or initial treatment of traumatic cerebral edema; this code is exclusively for sequelae.
