Preterm labor (O60) ICD-10-CM

Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- onset (spontaneous) of labor before 37 completed weeks of gestation
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 O60 range.
Obstetric Labor, Premature
Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).
About the O60 Code Range
Preterm labor begins before term. It may stop without delivery, lead to a preterm delivery, or be followed by a term delivery.
O60.0 covers preterm labor without delivery and separates cases by trimester. O60.1 covers preterm labor with preterm delivery and distinguishes when labor and delivery occur. O60.2 covers term delivery after preterm labor and separates cases by the trimester of labor.
For O60.1 and O60.2, the seventh character identifies the fetus or indicates that identification is not applicable or unspecified.
