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 2026, 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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the Z37 range.
Fetal Viability
The potential of the FETUS to survive outside the UTERUS after birth, natural or induced. Fetal viability depends largely on the FETAL ORGAN MATURITY, and environmental conditions.
Postpartum Hemorrhage
Excess blood loss from uterine bleeding associated with OBSTETRIC LABOR or CHILDBIRTH. It is defined as blood loss greater than 500 ml or of the amount that adversely affects the maternal physiology, such as BLOOD PRESSURE and HEMATOCRIT. Postpartum hemorrhage is divided into two categories, immediate (within first 24 hours after birth) or delayed (after 24 hours postpartum).
About the Z37 Code Range
The ICD-10 code section Z37 covers the outcome of delivery, documenting the results of childbirth such as live births, stillbirths, and multiple births. These codes are essential for accurately recording the specifics of a delivery event.
Within this section, codes range from Z37.0 for a single live birth—including cases with meconium in the amniotic fluid—to Z37.1 for a single stillbirth. Multiple birth outcomes are detailed using codes like Z37.2 for twins both liveborn, Z37.3 for twins with one liveborn and one stillborn, and Z37.4 for twins both stillborn. Additional codes—such as Z37.51 for triplets all liveborn or Z37.61 for triplets with some liveborn—help specify the number and live status in multiple births. The Z37.9 code captures unspecified outcomes, including varied delivery circumstances or complications. These distinctions aid medical coders and professionals in precisely capturing delivery results, including details commonly referred to as “single live birth,” “twins both liveborn,” or “triplets all liveborn.”
