Traum subrac hem w LOC >24 hr w ret consc lev, subs

This code signifies a traumatic subarachnoid hemorrhage where the patient experienced a loss of consciousness exceeding 24 hours, but has since returned to their baseline neurological status. It indicates a recovery phase from a severe head injury involving bleeding into the subarachnoid space.

Apply this code for follow-up encounters when a patient, previously diagnosed with a traumatic subarachnoid hemorrhage and prolonged loss of consciousness, is documented as having regained their pre-injury conscious level. Documentation should explicitly state the duration of unconsciousness and the current neurological status reflecting a return to baseline.

• Ensure the documentation clearly specifies "return to pre-existing conscious level" to differentiate from other recovery statuses.
• This "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Always code the underlying traumatic injury first, followed by this code.
