Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Angioimmunoblastic lymphadenopathy with dysproteinemia (AILD)
Other codes that can never be billed with C86.5
These codes carry an Excludes1 note pointing at C86.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C86.5 alone.
- C84.ZOther mature T/NK-cell lymphomas
Risk adjustment
C86.5 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
C86.5 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
