Poisoning by penicillins

This code signifies an adverse reaction to penicillin, specifically a poisoning event. This typically involves an overdose or toxic effect of the medication, rather than an allergic reaction.

Use this code when documentation clearly indicates a patient has experienced poisoning due to penicillin. This includes scenarios such as accidental overdose, intentional overdose, or adverse effects resulting from an inappropriately high dose. Documentation should specify "poisoning" or "toxic effect" of penicillin.

• Differentiate carefully between poisoning and allergic reaction; allergic reactions to penicillin are coded differently.
• Always sequence this code as the primary diagnosis if it is the reason for the encounter.
• Look for specific documentation of the penicillin agent involved, if available, to ensure accuracy.
