Questions About I89Overview

What is the ICD-10 code for other noninfective disorders of lymphatic vessels and lymph nodes?

I89 is the ICD-10-CM category for other noninfective disorders of lymphatic vessels and lymph nodes, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is I89 a billable code?

No. This is a category header that groups the codes for other noninfective disorders of lymphatic vessels and lymph nodes, and headers cannot be submitted on claims. Claims for other noninfective disorders of lymphatic vessels and lymph nodes need a more specific code from this category, such as I89.0, I89.1, and I89.8.

Can I89 be reported with N50.89?

Not as a rule. The Excludes1 note on I89 lists "chylocele, tunica vaginalis (nonfilarial) NOS (N50.89)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
