Diffuse TBI w LOC >24 hr w return to conscious levels, init

This code signifies a widespread brain injury resulting from trauma, where the patient experienced a loss of consciousness exceeding 24 hours. Crucially, the patient's neurological status subsequently returned to their baseline level of consciousness. This represents the initial phase of treatment for this specific injury.

Apply this code when documentation clearly indicates a diffuse traumatic brain injury with a prolonged period of unconsciousness (over 24 hours) and a documented return to the patient's pre-injury conscious state. This code is appropriate for the initial hospital admission or encounter for this specific injury. Supporting documentation would include neurological assessments, Glasgow Coma Scale (GCS) scores, and physician notes detailing the duration of unconsciousness and recovery.

• Ensure the documentation explicitly states "diffuse" brain injury and a loss of consciousness "greater than 24 hours."
• Verify that the patient's conscious level returned to their pre-existing baseline; otherwise, a different code for altered consciousness or persistent deficits would be more appropriate.
• This code is for the "initial encounter" only; subsequent encounters for the same injury would require a different seventh character.
