Z90.49 — Acquired absence of other specified parts of digestive tract
Is Z90.49 billable?
Yes, but Z90.49 is an unspecified code. Z90.49 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, Z90.49 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting Z90.49 — the more specific alternatives are listed below.

What Medicare edits apply to Z90.49?

CMS will reject this code as the principal diagnosis on an inpatient claim. It describes something other than the condition chiefly responsible for the admission.
Which MS-DRGs does Z90.49 group to?
Z90.49 sits in MDC 23 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

Excludes1 — never code together — inherited from Z90
The conditions below can never be reported together with Z90.49 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 Z90.49, but a patient may have both at the same time. When documentation supports it, Z90.49 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 Z90.49 is sequenced first depends on the reason for the encounter.
- any follow-up examination (Z08-Z09)
