Poisoning by BCG vaccine

This code signifies an adverse reaction or toxic effect resulting from the administration of a Bacillus Calmette-Guérin (BCG) vaccine. This typically involves systemic or localized symptoms beyond expected minor vaccine side effects, indicating a true poisoning or overdose.

Use this code when documentation clearly states a patient experienced poisoning due to a BCG vaccine, such as an accidental overdose, incorrect administration, or an idiosyncratic toxic reaction. Supporting documentation should detail the vaccine administered, the adverse symptoms, and a causal link to the BCG vaccine.

• Differentiate from allergic reactions (995.20-995.29) or normal vaccine side effects.
• Always sequence this code as the primary diagnosis if it is the reason for the encounter.
• Look for specific terms like "poisoning," "overdose," or "toxic effect" directly linked to the BCG vaccine.
