Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Kappa light chain deficiency
Risk adjustment
D80.8 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.
Medicare coverage
D80.8 is named in 26 Medicare coverage policies — 26 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How D80.8 is indexed
