Poisoning by macrolides, assault, initial encounter

This code signifies a patient presenting with adverse effects resulting from the intentional administration of a macrolide antibiotic by another person with the intent to cause harm. The patient is in the acute phase of treatment for this poisoning.

Apply this code when documentation clearly indicates poisoning by a macrolide antibiotic due to an assault, and the patient is receiving initial active treatment for the toxic effects. This would include scenarios such as a patient admitted to the emergency department or hospital for stabilization and management of macrolide overdose inflicted by another.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires an external cause code (e.g., Y03.-) to fully describe the circumstances of the assault.
• Do not use for accidental poisoning, self-harm, or adverse effects occurring during therapeutic use.
