How is C86.5 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to C86.5. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Lymphadenopathy › angioimmunoblastic, with dysproteinemia (generalized)
  • Lymphoma › angioimmunoblastic T-cell (of) (malignant)

Inclusion terms

Alternative wording in documentation that is classified to C86.5.

  • Angioimmunoblastic lymphadenopathy with dysproteinemia (AILD)

Excludes1 — never code together — inherited from C86

The conditions below can never be reported together with C86.5 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • anaplastic large cell lymphoma, ALK negative (C84.7-)
  • anaplastic large cell lymphoma, ALK positive (C84.6-)
  • mature T/NK-cell lymphomas (C84.-)
  • other specified types of non-Hodgkin lymphoma (C85.8-)

Excludes2 — not included here — inherited from C81-C96

The conditions below are not part of C86.5, but a patient may have both at the same time. When documentation supports it, C86.5 and the excluded code may both be reported.

  • Kaposi's sarcoma of lymph nodes (C46.3)
  • secondary and unspecified neoplasm of lymph nodes (C77.-)
  • secondary neoplasm of bone marrow (C79.52)
  • secondary neoplasm of spleen (C78.89)
