About coding uranium exposure
The ICD-10-CM code for uranium exposure is Z77.012 (Contact with and (suspected) exposure to uranium).
Within Z77.01 (contact with and (suspected) exposure to hazardous metals), Z77.012 is specifically for contact with and (suspected) exposure to uranium. Related codes cover arsenic (Z77.010), lead (Z77.011), gadolinium (Z77.013) and other hazardous metals (Z77.018).
Don't report Z77.012 together with the conditions in its Excludes1 note: retained depleted uranium fragments (Z18.01).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
