C96 — Other and unspecified malignant neoplasms of lymphoid, hematopoietic and related tissue
Is C96 billable?
No — C96 is a non-billable header code. C96 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 11 billable codes beneath C96.

Excludes1 — never code together
The conditions below can never be reported together with C96 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- 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 C96, but a patient may have both at the same time. When documentation supports it, C96 and the excluded code may both be reported.

How long has C96 existed?
C96 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with C96?
ICD-10-CM declares these codes mutually exclusive with C96 — exactly one of each pair can be correct for a given encounter.
