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

This code signifies a past injury involving both bruising and tearing of the cerebrum, the largest part of the brain, where the patient experienced a loss of consciousness lasting between 31 and 59 minutes at the time of the initial injury. The "sequela" indicates that this code is used to report residual effects or complications arising from that original brain trauma, not the acute injury itself.

Use this code when documenting follow-up care for a patient who previously sustained a cerebral contusion and laceration with a specific duration of unconsciousness, and who is now presenting with ongoing symptoms or complications directly attributable to that past injury. Documentation should clearly link the current condition to the prior brain trauma and specify the initial loss of consciousness duration.

• This "S" code indicates a sequela, meaning it should only be used for conditions that are residual effects of the initial injury, not for the acute injury itself.
• Ensure the medical record explicitly states the loss of consciousness duration was between 31 and 59 minutes at the time of the original injury.
• Always sequence the sequela code first, followed by codes for the specific residual conditions (e.g., cognitive deficits, post-traumatic epilepsy).
