Toxic effect of chromium and its compounds, acc, sequela

This code signifies a long-term health problem or residual effect resulting from an accidental exposure to chromium or its compounds. These sequelae can manifest as chronic organ damage, persistent dermatological conditions, or neurological deficits that developed after the initial toxic event. The original poisoning event is no longer acute, but its lasting impact on the patient's health is being addressed.

Apply this code when documenting a patient presenting with a chronic condition directly attributable to a past, unintentional chromium poisoning. This would include follow-up visits for ongoing management of kidney failure, liver damage, or chronic skin lesions that were caused by an accidental exposure to chromium. Do not use for acute poisoning or intentional self-harm.

• Always code the specific sequela first, followed by this code to indicate the cause.
• Ensure documentation clearly links the current condition to a past accidental chromium exposure.
• Verify the "S" seventh character is appropriate, indicating a sequela, not an initial encounter or subsequent encounter for the acute poisoning.
