Poisoning by dental drugs topically applied

This code indicates an adverse health effect resulting from the ingestion, absorption, or other systemic exposure to a dental drug that was intended for topical application. This includes situations where the drug was applied to the oral mucosa or teeth but subsequently caused systemic toxicity due to accidental swallowing or excessive absorption.

Use this code when documentation clearly states a patient experienced poisoning from a dental medication, such as a topical anesthetic or fluoride, that was applied to the oral cavity. This typically occurs in cases of accidental ingestion, overuse, or hypersensitivity reactions to topically applied agents.

• Always code the specific manifestation of the poisoning (e.g., nausea, cardiac arrhythmia) as a primary diagnosis, with this code as a secondary diagnosis to identify the cause.
• Distinguish from adverse effects of systemically administered dental drugs or local adverse reactions (e.g., contact dermatitis) which would use different codes.
• Ensure documentation specifies "topically applied" to differentiate from orally ingested or injected dental drugs.
