Traumatic subcutaneous emphysema, subsequent encounter

This code signifies the presence of air or gas trapped under the skin due to an injury, specifically when the patient is receiving follow-up care for this condition. It indicates that the initial treatment has been provided, and the patient is now undergoing further management, monitoring, or recovery.

Use this code when documenting a patient's visit for ongoing treatment, evaluation, or management of traumatic subcutaneous emphysema after the initial encounter. This includes scenarios such as wound checks, follow-up imaging, or monitoring for resolution of the air pocket.

• Ensure documentation clearly indicates that this is not the initial treatment for the traumatic subcutaneous emphysema.
• Always sequence this code after the primary injury code that caused the emphysema.
• Verify the "D" seventh character is appropriate for a subsequent encounter; avoid using "A" (initial) or "S" (sequela) unless clinically indicated.
