Poisoning by penicillins, intentional self-harm, init encntr

This code signifies a patient's self-inflicted poisoning specifically from penicillin, indicating a deliberate act to cause harm. The "initial encounter" designation means this is the first time the patient is receiving active treatment for this particular poisoning event.

This code is appropriate when documentation clearly states a patient intentionally overdosed on penicillin, such as in a suicide attempt or gesture. It should be used for the initial hospital visit or encounter where the poisoning is diagnosed and treatment is initiated.

• Always verify the intent (intentional self-harm) and the substance (penicillin) from the medical record.
• Ensure the encounter is indeed the "initial" one for this specific poisoning episode; subsequent care would use a different encounter character.
• Remember to also code any associated mental health conditions, such as depression or suicidal ideation, as secondary diagnoses.
