I89.8 — Other specified noninfective disorders of lymphatic vessels and lymph nodes
I89.8 is a billable, specific ICD-10-CM code for other specified noninfective disorders of lymphatic vessels and lymph nodes. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.

- Lipomelanotic reticulosis
- Lymph node or vessel fistula
- Lymph node or vessel infarction
- Lymph node or vessel rupture
Other codes that can never be billed with I89.8
These codes carry an Excludes1 note pointing at I89.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I89.8 alone.
- D76Other specified diseases with participation of lymphoreticular and reticulohistiocytic tissue
Risk adjustment
I89.8 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
I89.8 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
