Z90 — Acquired absence of organs, not elsewhere classified
Is Z90 billable?
No — Z90 is a non-billable header code. Z90 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 22 billable codes beneath Z90.

Excludes1 — never code together
The conditions below can never be reported together with Z90 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- congenital absence - see Alphabetical Index
Excludes2 — not included here
The conditions below are not part of Z90, but a patient may have both at the same time. When documentation supports it, Z90 and the excluded code may both be reported.
- postprocedural absence of endocrine glands (E89.-)
Includes
