Diffuse TBI w LOC of 6 hours to 24 hours, subs

This code signifies a diffuse traumatic brain injury (TBI) where the patient experienced a loss of consciousness (LOC) lasting between 6 and 24 hours. "Diffuse" indicates widespread brain damage rather than a localized lesion. This diagnosis is used for a patient who is receiving follow-up care for this specific injury.

Use this code for a patient who has previously been treated for a diffuse TBI with a 6-24 hour LOC and is now presenting for subsequent care, such as rehabilitation, medication management, or follow-up appointments. Documentation must clearly state the diffuse nature of the injury, the duration of LOC, and confirm that this is not the initial encounter for the acute injury.

• Ensure documentation specifies "diffuse" TBI and the exact duration of LOC to differentiate from other TBI types and LOC durations.
• Verify that the encounter is indeed "subsequent" and not the initial acute care for the injury; otherwise, an acute encounter code would be more appropriate.
• Always code any associated neurological deficits or complications (e.g., post-concussion syndrome, cognitive deficits) as additional diagnoses.
