Poisoning by expectorants, intentional self-harm, subs

This code signifies a deliberate act of self-harm involving an overdose or misuse of medications intended to clear respiratory passages, such as guaifenesin or mucolytics. The patient is presenting for follow-up care or treatment of sequelae related to this poisoning event.

This code is appropriate when documenting subsequent encounters for patients who intentionally poisoned themselves with expectorants. This includes follow-up appointments, ongoing treatment for organ damage, or mental health evaluations related to the self-harm attempt. It should be used after the initial acute phase of treatment.

• Ensure documentation clearly states "intentional self-harm" and specifies the substance as an expectorant.
• Verify this is a subsequent encounter; for the initial encounter, a different seventh character would be appended.
• Always code with an accompanying mental health diagnosis, such as a mood disorder or suicidal ideation, when applicable.
