Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Family history of familial combined hyperlipidemia
Excludes2 inherited from the categories above Z83.438
Also inherited, and the opposite of Excludes1: these conditions are not part of Z83.438, but a patient can have both, so you may code both.
Risk adjustment
Z83.438 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.
