Inhalation of dry ice, subsequent encounter

This code indicates a patient presenting for follow-up care or complications arising from a previous exposure to dry ice via inhalation. This could include respiratory symptoms such as coughing, shortness of breath, or chest pain, or systemic effects like headache or dizziness, that are being addressed after the initial incident.

Apply this code when a patient returns for evaluation or treatment of symptoms or conditions related to an earlier dry ice inhalation event. This is appropriate for subsequent visits for ongoing management, monitoring of recovery, or addressing delayed complications.

• Ensure documentation clearly indicates this is not the initial encounter for the dry ice inhalation.
• Always code with additional codes for specific symptoms or conditions resulting from the inhalation (e.g., J45.909 for asthma, R06.02 for shortness of breath).
• Verify the encounter type (initial, subsequent, sequela) is accurately reflected in the 7th character.
