Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- DNR status
Other codes that can never be billed with Z66
These codes carry an Excludes1 note pointing at Z66. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Z66 alone.
- Y66Nonadministration of surgical and medical care
Risk adjustment
Z66 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 Z66 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 Z66.
