Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Obliteration of lymphatic vessels

Other codes that can never be billed with I97.2

These codes carry an Excludes1 note pointing at I97.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I97.2 alone.

  • I89.0Lymphedema, not elsewhere classified

Risk adjustment

I97.2 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

I97.2 is named in 7 Medicare coverage policies 6 listing it as supporting medical necessity, and 1 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
