C85 (Other specified and unspecified types of non-Hodgkin lymphoma) compared with C86 (Other specified types of T/NK-cell lymphoma), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. C85 carries an Excludes1 note covering C86: “other specified types of T/NK-cell lymphoma (C86.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
