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

This code signifies a diffuse traumatic brain injury (TBI) where the patient experienced a loss of consciousness (LOC) lasting between 6 and 24 hours. The "S" at the end indicates that this code is for the sequela, meaning it describes a condition or complication that arises as a direct result of the initial TBI, occurring after the acute phase of the injury has passed.

Use this code when documenting the long-term effects or complications stemming from a diffuse TBI that initially presented with a LOC between 6 and 24 hours. This code is appropriate for follow-up encounters where the patient is being treated for residual symptoms or conditions directly attributable to the past TBI. Documentation should clearly link the current condition to the previous TBI and specify the initial LOC duration.

• Always sequence this sequela code after the code for the specific residual condition being treated (e.g., cognitive deficits, post-concussive syndrome).
• Ensure documentation explicitly states "sequela" or indicates that the current condition is a long-term effect of the prior TBI.
• Verify the initial LOC duration from the patient's medical history; codes for TBI with different LOC durations exist and are not interchangeable.
