Traum subdr hem w LOC of 30 minutes or less, sequela

This code signifies a chronic or residual effect stemming from a traumatic subdural hemorrhage where the patient experienced a brief loss of consciousness (30 minutes or less) at the time of the initial injury. It indicates that the patient is currently experiencing ongoing symptoms or complications directly attributable to that past head trauma.

Apply this code when documentation clearly links a current neurological deficit, cognitive impairment, or other persistent symptom to a previously sustained traumatic subdural hemorrhage with a documented loss of consciousness of 30 minutes or less. This code is used for follow-up encounters after the initial acute injury has resolved, but sequelae persist.

• Always sequence this sequela code after the code(s) describing the specific residual condition(s) (e.g., hemiplegia, cognitive deficits).
• Ensure the medical record explicitly states the subdural hemorrhage was traumatic and specifies the duration of loss of consciousness as 30 minutes or less.
• Do not use for acute subdural hemorrhages or for sequelae of non-traumatic subdural hemorrhages.
