Outcome of delivery (Z37) ICD-10-CM
The Z37 code range covers outcome of delivery with 22 ICD-10-CM diagnosis codes. 19 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- This category is intended for use as an additional code to identify the outcome of delivery on the mother's record. It is not for use on the newborn record.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Multiple Birth
Multiple fetuses birthed live or dead in a single pregnancy regardless of gestational age, and regardless of whether the fetuses were birthed on different dates.
About the Z37 Code Range
The outcome of a delivery describes whether one baby or multiple babies are born and whether they are liveborn or stillborn.
Z37.0 and Z37.1 separate a single live birth from a single stillbirth. The twin codes distinguish both liveborn, one liveborn and one stillborn, or both stillborn.
Other multiple births are grouped as all liveborn, some liveborn, or all stillborn. Within the all-liveborn and some-liveborn groups, further codes distinguish triplets, quadruplets, quintuplets, sextuplets, and unspecified or other multiple births. Z37.9 identifies an unspecified delivery outcome.
