Poisoning by diagnostic agents, intentional self-harm, subs

This code signifies a patient presenting for follow-up care related to a self-inflicted poisoning event involving diagnostic agents. This could include substances like contrast media, radiopharmaceuticals, or other chemicals used for diagnostic purposes, taken with the intent to cause harm. The "subsequent encounter" indicates that the initial treatment for the acute poisoning has already occurred.

Use this code for outpatient visits, follow-up hospital admissions, or other encounters where the patient is receiving ongoing care for complications, psychological evaluation, or management directly stemming from a previous intentional self-poisoning with a diagnostic agent. This applies after the initial acute phase of treatment has concluded.

• Always sequence this code after the primary diagnosis for the specific condition being treated during the subsequent encounter.
• Ensure documentation clearly indicates the poisoning was intentional self-harm and that this is not the initial treatment encounter.
• Consider additional codes for any resulting medical complications or mental health diagnoses related to the self-harm attempt.
