Toxic effect of oth inorganic substances, undetermined, init

This code signifies a harmful reaction in a patient due to exposure to an inorganic substance not specifically classified elsewhere, where the intent of the exposure (e.g., accidental, intentional self-harm) cannot be determined. The "initial encounter" designation indicates that the patient is receiving active treatment for the toxic effect.

Apply this code when a patient presents with symptoms of poisoning from an inorganic substance (e.g., certain heavy metals, industrial chemicals) and the medical record does not specify the intent of the exposure. This is appropriate for the initial visit where diagnosis and treatment for the acute toxic effect are being provided.

• Always seek to identify the specific inorganic substance and the intent of exposure if documented.
• If the intent is known (e.g., accidental, assault), use the appropriate intent character (A, D, S) and a more specific T code if available.
• This code is for the initial phase of treatment; subsequent encounters for the same toxic effect will require a different seventh character.
