Inclusion terms

Alternative wording in documentation that is classified to Z90.6.

Acquired absence of bladder

Excludes1 — never code together — inherited from Z90

The conditions below can never be reported together with Z90.6 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 — inherited from Z90

The conditions below are not part of Z90.6, but a patient may have both at the same time. When documentation supports it, Z90.6 and the excluded code may both be reported.

postprocedural absence of endocrine glands (E89.-)

Code also — inherited from Z77-Z99

Two codes may be needed to describe the condition fully. Whether Z90.6 is sequenced first depends on the reason for the encounter.
