Is C85 billable?

No — C85 is a non-billable header code. C85 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 44 billable codes beneath C85.

Excludes1 — never code together

The conditions below can never be reported together with C85 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

other specified types of T/NK-cell lymphoma (C86.-)
personal history of non-Hodgkin lymphoma (Z85.72)

Excludes2 — not included here — inherited from C81-C96

The conditions below are not part of C85, but a patient may have both at the same time. When documentation supports it, C85 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)
