Contus/lac left cerebrum w LOC of 31-59 min, sequela

This code signifies a traumatic brain injury involving both bruising (contusion) and tearing (laceration) of the left cerebral hemisphere, accompanied by a moderate period of unconsciousness lasting between 31 and 59 minutes. The "S" at the end indicates this is a sequela code, meaning it describes a late effect or complication of the initial injury.

Apply this code when documenting the long-term effects or residual conditions stemming from a past left cerebral contusion and laceration that initially presented with a loss of consciousness between 31 and 59 minutes. Documentation should clearly link the current condition to the previous brain injury and specify the initial duration of unconsciousness.

• Always use a sequela code (ending in "S") for conditions that are residual effects of a past injury, not for the initial acute injury.
• Ensure the medical record explicitly states the laterality (left cerebrum) and the precise duration of loss of consciousness from the initial event.
• Do not confuse this with codes for concussion or other less severe traumatic brain injuries; this code specifies both contusion and laceration.
