Epidural hemorrhage w LOC of 30 minutes or less, sequela

This code signifies a delayed effect or complication arising from an epidural hemorrhage that initially presented with a brief period of unconsciousness (30 minutes or less). It indicates that the acute phase of the hemorrhage has passed, but the patient is now experiencing residual symptoms or conditions directly attributable to that past injury.

Apply this code when documentation clearly indicates a sequela (e.g., chronic headache, cognitive deficits, neurological impairment) resulting from a previously sustained epidural hemorrhage where the initial loss of consciousness was 30 minutes or less. This code is appropriate for encounters addressing these long-term effects, not the initial acute injury.

• Always sequence this sequela code after the code for the specific residual condition being treated (e.g., G93.40 for unspecified encephalopathy).
• Ensure documentation explicitly links the current condition to the past epidural hemorrhage and specifies the initial duration of unconsciousness.
• Do not use this code for acute or active epidural hemorrhages; those require codes from the S06.4X1A or S06.4X1D categories.
