Contus/lac l cereb w LOC of 30 minutes or less, sequela

This code describes a past injury involving a bruise and tear to the left cerebral hemisphere, which resulted in a brief loss of consciousness lasting no more than 30 minutes. The "sequela" designation indicates that this code is used to report a current condition or complication that is a residual effect of that initial brain injury.

Use this code when a patient presents with a current symptom, disorder, or condition directly attributable to a previous contusion and laceration of the left cerebrum with brief loss of consciousness. Documentation must clearly link the current presentation to the historical brain injury. This code is appropriate for follow-up care related to the long-term effects of the initial trauma.

• Requires a seventh character "S" for sequela, indicating a late effect of the injury.
• Do not use for initial encounters or subsequent encounters for active treatment of the acute injury.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., cognitive deficits, post-traumatic epilepsy).
