Toxic effect of carbon dioxide, assault, subs encntr

This code signifies the toxic effects resulting from exposure to carbon dioxide due to an intentional act of harm by another person, specifically when the patient is receiving routine care during the healing or recovery phase. It indicates that the initial injury has been treated, and the patient is now in a follow-up or rehabilitation period.

Use this code for a patient presenting for follow-up appointments, medication management, or physical therapy related to carbon dioxide poisoning that occurred as a result of an assault. This applies after the acute phase of treatment for the poisoning has concluded.

• Ensure documentation clearly states the carbon dioxide exposure was due to an assault and that this is a subsequent encounter.
• Do not use for initial encounters or active treatment of the acute poisoning.
• Always code external cause codes (Y codes) to provide further detail on the circumstances of the assault.
