Poisoning by dental drugs, topically applied, undet, subs

This code signifies a poisoning event resulting from the use of dental drugs applied topically, where the intent (e.g., accidental, intentional self-harm) cannot be determined. This diagnosis is used when the patient is receiving follow-up care for the sequelae or ongoing treatment related to the initial poisoning.

Apply this code for patients presenting for subsequent treatment, monitoring, or management of complications arising from an undetermined topical dental drug poisoning. Examples include follow-up for oral mucosal irritation, systemic effects, or other adverse reactions after the initial acute phase.

• Ensure documentation clearly states the poisoning was due to a topically applied dental drug and the intent is explicitly "undetermined."
• This "D" seventh character indicates a subsequent encounter, meaning the patient is receiving care after the initial treatment of the poisoning.
• Always review the medical record for specific details regarding the drug involved and the nature of the follow-up care to support this code.
