Traum subdr hem w LOC of 1-5 hrs 59 min, subs

This code signifies a traumatic subdural hemorrhage where the patient experienced a loss of consciousness lasting between one hour and five hours and fifty-nine minutes. It specifically indicates that the patient is receiving follow-up care for this condition after the initial treatment phase.

Apply this code for patients presenting for ongoing management, rehabilitation, or follow-up appointments related to a previously diagnosed traumatic subdural hemorrhage with the specified duration of unconsciousness. Documentation should clearly state "subsequent encounter" or similar language indicating care after the initial acute phase, along with the specific duration of loss of consciousness.

• Ensure documentation explicitly states "subsequent encounter" to differentiate from initial or sequela encounters.
• Verify the exact duration of loss of consciousness; codes exist for other timeframes (e.g., less than 1 hour, 6-24 hours).
• Always sequence this code after any codes for external causes of injury (e.g., fall, motor vehicle accident) if applicable for the current encounter.
