S06.0XAD
ICD-10-CMConcussion with loss of consciousness status unknown, subsequent encounter
This code signifies a concussion where the duration of loss of consciousness (LOC) is not documented, and the patient is receiving follow-up care for this injury. It indicates the patient is in the healing phase after the initial acute treatment.
Apply this code for patients presenting for ongoing management of a concussion, such as follow-up appointments, rehabilitation, or monitoring for post-concussive syndrome, when the initial encounter for the injury has already been coded. Documentation should clearly state "concussion," "subsequent encounter," and indicate that LOC status is unknown or unspecified.
