Poisn by selective serotonin reuptake inhibtr, acc, init

This code signifies an accidental overdose or adverse reaction to a selective serotonin reuptake inhibitor (SSRI) due to unintentional ingestion or misadministration. Patients may present with symptoms ranging from nausea and vomiting to serotonin syndrome, depending on the dosage and individual sensitivity.

Apply this code when a patient presents to an emergency department or clinic with symptoms of SSRI poisoning, and the ingestion is documented as accidental or unintentional. This includes situations where a patient mistakenly takes too much medication, takes another person's medication, or has an unexpected adverse reaction to a prescribed dose due to an error in administration.

• Ensure documentation clearly states the poisoning was "accidental" or "unintentional."
• Always assign an additional code for the specific SSRI involved, if known, from categories T43.20-T43.29.
• Remember the "A" at the end indicates an initial encounter for this condition. Subsequent encounters will require different seventh characters.
