Contus/lac left cerebrum with LOC status unknown, sequela

This code signifies a past injury to the left cerebral hemisphere involving both bruising (contusion) and tearing (laceration) of the brain tissue. The patient experienced a loss of consciousness at the time of the original injury, but the specific duration or details of that loss are not documented. This code is used to report the long-term effects or complications arising from this previous brain trauma.

This code is appropriate when a patient presents with ongoing neurological deficits or other sequelae directly attributable to a prior contusion and laceration of the left cerebrum with an unspecified loss of consciousness. Documentation should clearly link the current condition to the old injury and specify that it is a sequela. Examples include chronic headaches, cognitive impairments, or motor deficits resulting from the original trauma.

• Ensure documentation explicitly states "sequela" or "late effect" of the original injury.
• Do not use this code for acute injuries; it is specifically for the long-term consequences.
• Code any specific neurological deficits (e.g., hemiplegia, aphasia) separately as secondary diagnoses.
