Poisoning by oth vaccines and biolg substnc, assault, subs

This code signifies a poisoning event resulting from the administration of a vaccine or other biological substance, where the intent was assault. It is used when the patient is receiving follow-up care for the sequelae or complications of the initial poisoning.

Apply this code when a patient presents for ongoing treatment of adverse effects or injuries sustained from a vaccine or biological substance intentionally administered to harm them. This would include scenarios like managing chronic organ damage, neurological deficits, or persistent allergic reactions stemming from such an assault, after the initial acute phase of treatment.

• Always sequence this code after the primary diagnosis describing the specific manifestation of the poisoning.
• Ensure documentation clearly supports the "assault" intent and that this is a "subsequent encounter" for care.
• Do not use for accidental poisonings or adverse effects from properly administered vaccines; those require different codes.
