Toxic effect of arsenic and its compounds, undet, init

This code signifies a patient presenting with adverse health effects resulting from exposure to arsenic or its compounds, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined at the time of the initial encounter. The toxic effects can manifest in various organ systems, including gastrointestinal, neurological, and dermatological.

Use this code for initial encounters when a patient exhibits signs and symptoms of arsenic poisoning, and the medical record does not specify whether the exposure was accidental, intentional, or due to assault. This is appropriate when the provider is still investigating the circumstances surrounding the exposure.

• Always assign an additional code for the specific manifestations of arsenic toxicity (e.g., peripheral neuropathy, acute kidney failure).
• Do not use this code if the intent of the poisoning is clearly documented as accidental, intentional self-harm, or assault; instead, select the appropriate T57.0X1-, T57.0X2-, or T57.0X3- code.
• The "A" seventh character indicates an initial encounter for active treatment of the toxic effect.
