How is C88.8 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to C88.8. They show the wording a clinician may have documented, which often differs from the Tabular description.

Disease, diseased › immunoproliferative › specified NEC

Excludes1 — never code together — inherited from C88

The conditions below can never be reported together with C88.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

B-cell lymphoma, unspecified (C85.1-)
personal history of other malignant neoplasms of lymphoid, hematopoietic and related tissues (Z85.79)

Excludes2 — not included here — inherited from C81-C96

The conditions below are not part of C88.8, but a patient may have both at the same time. When documentation supports it, C88.8 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)
