Poisoning by appetite depressants, accidental, init

This code signifies an accidental overdose or adverse reaction to appetite suppressants, such as phentermine or diethylpropion, resulting in a poisoning event. The patient's exposure to the substance was unintentional, meaning it was not a deliberate act of self-harm or assault.

Apply this code when a patient presents to an emergency department or clinic due to an accidental ingestion of an appetite depressant beyond the prescribed dose, or an unexpected adverse reaction to a therapeutic dose. This code is specifically for the initial encounter for this poisoning event.

• Always use an additional code from T36-T50 to identify the specific appetite depressant involved.
• Ensure the documentation clearly states "accidental" or "unintentional" to support the seventh character "A" for initial encounter.
• Do not use this code for intentional self-harm or assault; refer to the appropriate codes for those scenarios.
