Poisoning by oth antidepressants, undetermined, init encntr

This code signifies an accidental or intentional overdose or toxic reaction to an antidepressant medication that is not specifically classified elsewhere (e.g., tricyclic, SSRI). The intent of the poisoning (accidental, intentional self-harm, assault, or undetermined) is unknown at the time of the initial encounter.

Apply this code when a patient presents with symptoms of poisoning from an antidepressant, and the specific type of antidepressant is not documented as a tricyclic or SSRI, and the circumstances surrounding the event are still under investigation. This is for the initial visit for this particular poisoning event.

• Ensure the documentation clearly states "undetermined" intent for the poisoning.
• Confirm this is the patient's first presentation for this specific poisoning episode.
• Always sequence this code first, followed by codes for any associated manifestations or complications of the poisoning.
