Unsp focal TBI w LOC of 1-5 hrs 59 min, subs

This code signifies a traumatic brain injury (TBI) where the specific type of focal injury (e.g., contusion, laceration) is not documented, and the patient experienced a loss of consciousness (LOC) lasting between 1 hour and 5 hours and 59 minutes. This particular code is for a subsequent encounter, meaning the patient is receiving follow-up care for the initial injury.

Use this code for follow-up visits or ongoing treatment for a TBI where the initial injury involved an unspecified focal brain trauma and a documented LOC within the 1-hour to 5-hour 59-minute timeframe. Documentation should clearly indicate the encounter type as subsequent and confirm the duration of the initial LOC.

• Ensure documentation specifies "unspecified focal" injury; if a specific focal injury (e.g., contusion) is identified, a more specific code should be used.
• Verify the duration of loss of consciousness is precisely within the 1 hour to 5 hours 59 minutes range; other durations have different codes.
• Confirm this is a subsequent encounter; initial encounters or sequelae have distinct coding.
