Emphysema (subcutaneous) resulting from a procedure, subs

This code signifies the presence of subcutaneous emphysema, a condition where air or gas is trapped under the skin, specifically when it arises as a complication of a medical or surgical procedure. This air typically originates from a ruptured airway or other compromised internal structure, dissecting into the subcutaneous tissues.

Use this code for follow-up encounters where a patient is being treated for or monitored for subcutaneous emphysema that developed as a direct result of a previous medical intervention. This includes situations where the patient is returning for wound care, medication adjustments, or imaging to assess the resolution of the air.

• Ensure documentation clearly links the subcutaneous emphysema to a specific prior procedure.
• Verify the encounter type is "subsequent" as indicated by the 7th character.
• Code any underlying cause of the emphysema (e.g., pneumothorax) if also present and documented.
