Is C16 billable?

No — C16 is a non-billable header code. C16 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 9 billable codes beneath C16.

Excludes2 — not included here

The conditions below are not part of C16, but a patient may have both at the same time. When documentation supports it, C16 and the excluded code may both be reported.

Excludes1 — never code together — inherited from C15-C26

The conditions below can never be reported together with C16 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

Kaposi's sarcoma of gastrointestinal sites (C46.4)

Excludes2 — not included here — inherited from C15-C26

The conditions below are not part of C16, but a patient may have both at the same time. When documentation supports it, C16 and the excluded code may both be reported.
