Z18.01 — Retained depleted uranium fragments
Z18.01 is a billable, specific ICD-10-CM code for retained depleted uranium fragments. It is valid for submission on a claim.
Other codes that can never be billed with Z18.01
These codes carry an Excludes1 note pointing at Z18.01. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z18.01 alone.
Risk adjustment
Z18.01 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
How Z18.01 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to Z18.01.
