Contus/lac left cerebrum w LOC of 30 minutes or less, subs

This code describes a traumatic brain injury involving bruising and tearing of the left cerebral hemisphere, accompanied by a brief period of unconsciousness (up to 30 minutes). This specific code is used for follow-up care after the initial injury has been treated.

Apply this code for patients presenting for subsequent care, such as follow-up appointments, rehabilitation, or monitoring, after sustaining a left cerebral contusion and laceration with a documented loss of consciousness of 30 minutes or less. Documentation should clearly indicate the "subsequent encounter" status and the specific nature of the brain injury.

• Ensure documentation specifies "subsequent encounter" to differentiate from the initial injury (A) or sequela (S).
• Verify the laterality (left cerebrum) and the duration of loss of consciousness (30 minutes or less).
• Do not use this code for injuries without loss of consciousness or for those with prolonged unconsciousness.
