Toxic effect of gadolinium, undetermined, sequela

This code signifies a long-term or residual health problem resulting from exposure to gadolinium, where the specific intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. It indicates that the patient is experiencing lasting effects from a past gadolinium toxicity.

Use this code for patients presenting with chronic symptoms or conditions directly attributed to a previous gadolinium exposure of unknown intent. This is appropriate when the acute phase of the toxic effect has passed, and the patient is being treated for the persistent sequelae. Examples include nephrogenic systemic fibrosis (NSF) or other long-term organ damage linked to gadolinium, where the original exposure circumstances are unclear.

• A seventh character of "S" (sequela) is mandatory for this code.
• Always sequence this code after the code(s) for the specific manifestation(s) of the sequela (e.g., code for NSF).
• Do not use this code for acute gadolinium toxicity; use codes with a different seventh character for initial or subsequent encounters.
