Contus/lac left cerebrum w LOC of unsp duration, sequela

This code signifies a chronic or late effect of a traumatic injury to the left cerebral hemisphere, specifically involving both bruising (contusion) and tearing (laceration) of the brain tissue. The initial injury was accompanied by a period of unconsciousness, the duration of which was not specified in the original encounter. This code is used when the patient is presenting for care related to the long-term consequences of this past brain injury.

Use this code for encounters where a patient is being treated for residual symptoms or complications directly attributable to a previously sustained contusion and laceration of the left cerebrum. Documentation should clearly link the current condition to the past brain injury and indicate that the initial injury involved loss of consciousness of unknown duration. This code is appropriate for follow-up care, rehabilitation, or management of chronic neurological deficits.

• Always ensure the "S" seventh character is appropriate for sequela; do not use for initial or subsequent active treatment.
• Document the specific neurological deficits or chronic conditions resulting from the sequela to support medical necessity.
• Do not use this code if the patient is still in the acute phase of injury or if the loss of consciousness duration was specified.
