Toxic effect of gadolinium, accidental (unintentional), init

This code signifies an adverse reaction to gadolinium, a contrast agent often used in MRI scans, occurring due to an accidental or unintentional exposure. The patient is experiencing the initial manifestation of toxicity from this substance.

Apply this code when a patient presents with symptoms of gadolinium toxicity, such as nephrogenic systemic fibrosis (NSF) or other systemic reactions, and the exposure was not intended or was an accidental overdose. This is appropriate for the initial workup and treatment of the acute toxic effect.

• Ensure documentation clearly states the exposure was accidental or unintentional, not a therapeutic misadventure or poisoning with intent.
• Confirm this is the initial encounter for the treatment of the toxic effect; subsequent encounters will require different seventh characters.
• Always code the specific manifestation of the gadolinium toxicity (e.g., NSF) in addition to this code.
