Poisoning by other and unspecified anti-infectives

This code signifies an adverse effect resulting from the ingestion, exposure, or administration of an anti-infective agent not specifically classified elsewhere. It encompasses both accidental and intentional poisonings by antibiotics, antivirals, antifungals, or antiparasitics when the specific drug is unknown or falls into an "other" category.

Apply this code when documentation clearly indicates a poisoning event due to an anti-infective, but the specific drug causing the reaction is not detailed enough to assign a more precise code. This is often seen in emergency department settings or when initial information is limited. Supporting documentation would include toxicology reports, physician notes detailing symptoms of poisoning, and a lack of specific drug identification.

• Always attempt to identify the specific anti-infective agent for a more precise code; this code is for unspecified or "other" scenarios.
• Sequence this code as the primary diagnosis when the poisoning is the reason for the encounter.
• Do not use for adverse effects from correctly prescribed and administered anti-infectives (use E-codes for adverse effects of therapeutic use).
