Poisoning by diagnostic agents, intentional self-harm, init

This code signifies a patient presenting with adverse effects from intentionally self-administering a diagnostic agent, such as a contrast dye or radiopharmaceutical, with the intent to harm themselves. The patient is in the acute phase of treatment for this poisoning.

Apply this code when documenting an overdose or toxic reaction to a substance used for diagnostic purposes, where the patient explicitly states or clinical evidence strongly suggests self-harm. This is appropriate for the initial hospital visit or encounter where the poisoning is first evaluated and treated.

• Always sequence this code first, followed by codes for the specific diagnostic agent (T36-T50 with 5th or 6th character indicating poisoning) and any resulting manifestations.
• Ensure documentation clearly supports intentional self-harm; if accidental, use the appropriate accidental poisoning code.
• Do not use this code for adverse effects of diagnostic agents administered correctly and without intent to harm (e.g., allergic reactions).
