Toxic effect of chromium and its compounds, acc, subs

This code signifies a patient presenting for follow-up care or treatment of adverse health effects resulting from an accidental exposure to chromium or its compounds. The toxic effects could range from skin irritation and respiratory issues to more severe systemic damage, depending on the type of chromium, dose, and duration of exposure.

Apply this code when a patient returns for ongoing management of symptoms or complications from an unintentional chromium poisoning that occurred previously. This includes visits for monitoring organ function, managing chronic skin lesions, or addressing persistent respiratory problems related to the initial exposure.

• Ensure the encounter is for subsequent care, not the initial treatment of the poisoning.
• Verify the exposure was accidental, not intentional self-harm or assault.
• Always code with an external cause code (e.g., X49.-) to specify the circumstances of the poisoning.
