Intcran inj w loss of consciousness of 31-59 min, sequela

This code describes the long-term effects or complications arising from a previously sustained intracranial injury that was not a concussion, diffuse axonal injury, or traumatic hemorrhage, and involved a loss of consciousness lasting between 31 and 59 minutes. This sequela could manifest as cognitive deficits, neurological impairments, or persistent post-traumatic symptoms.

Use this code when documenting the residual conditions or late effects directly attributable to a past intracranial injury with the specified duration of unconsciousness. The patient's medical record must clearly indicate a history of such an injury and the current presentation of a related sequela. This code is appropriate for follow-up visits addressing these chronic issues.

• Always sequence the sequela code first, followed by codes for the specific manifestations of the sequela (e.g., cognitive impairment, epilepsy).
• Ensure documentation explicitly states the prior intracranial injury and the duration of loss of consciousness to support this specific code.
• Distinguish from acute injury codes; this code is for chronic, residual conditions, not the initial injury encounter.
