Contus/lac r cereb w LOC >24 hr w/o ret consc w surv, subs

This code describes a severe traumatic brain injury involving bruising and tearing of the right cerebral hemisphere, resulting in a coma or vegetative state lasting over 24 hours, from which the patient has not recovered to their prior level of consciousness. This indicates a persistent and significant neurological deficit following the initial injury.

Use this code for follow-up encounters when a patient is still experiencing the long-term sequelae of a right cerebral contusion and laceration that initially caused a prolonged loss of consciousness (greater than 24 hours) and has not returned to their pre-injury conscious level. Documentation should clearly state the nature of the injury, the duration of unconsciousness, and the ongoing neurological status.

• Ensure documentation specifies the laterality (right cerebrum) and the duration of unconsciousness (greater than 24 hours).
• This "D" seventh character indicates a subsequent encounter for care after the initial treatment of the injury.
• Distinguish from codes for initial encounters or those where consciousness has returned to pre-existing levels.
