Poisoning by oth hormones and synthetic sub, undet, subs

This code signifies an adverse effect resulting from an unspecified hormone or synthetic substitute, where the intent (accidental, intentional self-harm, assault) cannot be determined. This particular encounter is a follow-up visit for the ongoing management or assessment of the poisoning.

Apply this code when a patient presents for continued care related to poisoning by a hormone or synthetic substitute, and the documentation does not specify whether the poisoning was accidental, intentional, or due to assault. This is appropriate for subsequent visits after the initial treatment of the poisoning event.

• Always sequence this code after the primary diagnosis for the specific effects of the poisoning.
• Ensure documentation clearly indicates a "subsequent encounter" for the poisoning, not the initial treatment.
• Avoid using this code if the intent of the poisoning (e.g., accidental, intentional self-harm) is documented; instead, use the appropriate intent-specific code.
