Poisoning by diagnostic agents, undetermined, init encntr

This code signifies an adverse event resulting from exposure to a diagnostic agent, such as a contrast medium or a radiopharmaceutical, where the intent of the exposure (e.g., accidental, intentional self-harm) cannot be determined. The patient is in the acute phase of treatment for this poisoning.

Apply this code when a patient presents with symptoms of poisoning directly attributable to a diagnostic agent, and the documentation does not specify whether the exposure was accidental, intentional, or due to assault. This is appropriate for the initial visit or encounter where the poisoning is being evaluated and treated.

• Always sequence this code first if it is the primary reason for the encounter.
• Requires an additional code to specify the specific diagnostic agent, if known.
• Do not use if the intent of the poisoning is clearly documented as accidental, intentional, or assault.
