Poisoning by appetite depressants, self-harm, init

This code signifies a patient presenting with adverse effects from intentionally self-administering appetite depressants (e.g., phentermine, diethylpropion) with the intent to harm themselves. The poisoning is acute, and the patient is receiving initial treatment for the overdose.

Apply this code when documenting an emergency department visit or initial hospitalization for an overdose of an appetite suppressant where the patient explicitly states or clinical evidence strongly suggests self-harm. This includes cases where the patient is brought in unconscious or critically ill due to the overdose.

• Always assign an additional code for the specific appetite depressant involved, if known (e.g., from T43.6X- series).
• Ensure documentation clearly supports "intentional self-harm" and "initial encounter" to justify this specific code.
• Do not use for accidental ingestions or adverse effects from therapeutic use; those require different codes.
