Traum hemor left cerebrum w LOC of 31-59 min, subs

This code signifies a brain injury involving bleeding within the left cerebral hemisphere caused by trauma, where the patient experienced a loss of consciousness lasting between 31 and 59 minutes. This specific code is used for encounters following the initial treatment of the injury.

Apply this code for follow-up visits, rehabilitation encounters, or subsequent hospitalizations for a patient previously diagnosed with a traumatic left cerebral hemorrhage with a documented loss of consciousness between 31 and 59 minutes. Documentation must clearly indicate the traumatic etiology, the specific brain region, the duration of unconsciousness, and that it is not the initial encounter.

• Ensure documentation specifies "subsequent encounter" for this code; otherwise, an initial encounter code (A) or sequela code (S) may be more appropriate.
• Verify the exact duration of loss of consciousness; codes vary significantly based on this detail.
• Always sequence this code after any associated external cause codes (V, W, X, Y) if applicable for the subsequent encounter.
