Toxic effect of gadolinium, assault, subsequent encounter

This code describes the adverse health effects resulting from exposure to gadolinium, specifically when the exposure was intentionally inflicted by another person (assault). The "subsequent encounter" indicates that the patient is receiving follow-up care for the initial injury or poisoning.

Use this code when a patient presents for ongoing treatment, monitoring, or management of symptoms related to gadolinium toxicity that occurred due to an assault. This would include scenarios where the patient is seen for chronic kidney disease progression, nephrogenic systemic fibrosis, or other long-term sequelae attributed to the toxic gadolinium exposure from an assault.

• Requires an external cause code (e.g., Y07.-) to fully describe the circumstances of the assault.
• Do not use for initial treatment of the acute toxic effect; that would require an "A" (initial encounter) seventh character.
• Ensure documentation clearly links the gadolinium toxicity to an assault and indicates ongoing care.
