Traumatic cerebral edema w LOC of 31-59 min, subs

This code signifies a subsequent encounter for a patient diagnosed with traumatic cerebral edema, a swelling of the brain tissue resulting from head trauma. Specifically, it indicates that the patient experienced a loss of consciousness lasting between 31 and 59 minutes at the time of the initial injury. This code is used when the patient is receiving active treatment for the cerebral edema or its sequelae.

Use this code for follow-up visits, rehabilitation sessions, or ongoing medical management related to traumatic cerebral edema where the initial injury involved a moderate period of unconsciousness. Documentation should clearly state "subsequent encounter" or indicate ongoing care for the condition, along with a history of traumatic cerebral edema and the specific duration of loss of consciousness. This code is appropriate when the patient is still under active treatment for the injury.

• Ensure the documentation specifies "subsequent encounter" and not "initial encounter" or "sequela" for appropriate code assignment.
• Verify the duration of loss of consciousness (31-59 minutes) is explicitly documented; other durations require different codes.
• Always sequence this code after any codes for the specific type of head injury (e.g., concussion, intracranial hemorrhage) if applicable.
