C86 — Other specified types of T/NK-cell lymphoma
Is C86 billable?
No — C86 is a non-billable header code. C86 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 14 billable codes beneath C86.

Excludes1 — never code together
The conditions below can never be reported together with C86 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from C81-C96
The conditions below are not part of C86, but a patient may have both at the same time. When documentation supports it, C86 and the excluded code may both be reported.

How long has C86 existed?
C86 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.
