I89.0Lymphedema, not elsewhere classified

Billable / specific codeICD-10-CM

I89.0 is a billable, specific ICD-10-CM code for lymphedema, not elsewhere classified. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • postmastectomy lymphedema (I97.2)

Inclusion terms

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

  • Elephantiasis (nonfilarial) NOS
  • Lymphangiectasis
  • Obliteration, lymphatic vessel
  • Praecox lymphedema
  • Secondary lymphedema

Risk adjustment

I89.0 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

I89.0 is named in 15 Medicare coverage policies 14 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.
