Primary blast injury of brain, NEC without LOC, subs

This code signifies a brain injury sustained directly from the force of a blast, such as from an explosion, where the patient did not lose consciousness. It specifically applies to primary blast injuries not classified under more specific codes. This diagnosis indicates the patient is in a subsequent phase of care for this injury.

This code is appropriate for encounters following the initial treatment of a primary blast injury to the brain, where the patient's consciousness was not impaired at the time of injury. Documentation should clearly state "primary blast injury," specify the absence of loss of consciousness, and indicate that this is not the initial encounter for this condition. It's used for follow-up visits, rehabilitation, or ongoing management.

• Ensure documentation explicitly states "primary blast injury" and "without loss of consciousness" for accurate code assignment.
• The 7th character "D" indicates a subsequent encounter; verify this aligns with the patient's current phase of care.
• Differentiate from secondary, tertiary, or quaternary blast injuries, which have distinct ICD-10-CM codes.
