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.

About the O60 Code Range
ICD-10 code section O60 is used to classify and document preterm labor, a condition where labor begins before 37 weeks of pregnancy. These codes cover cases of preterm labor both without and with delivery, specifying the trimester involved and details about multiple fetuses when applicable.
This section includes codes such as O60.0 for preterm labor without delivery, with further subdivisions like O60.00 describing unspecified trimester preterm contractions, also known by terms like premature uterine contraction or premature labor. When preterm labor results in delivery, codes under O60.1 apply, including options to specify fetus number and trimester, for example, O60.10X0. The list also recognizes variations like term delivery with preceding preterm labor (coded as O60.2). Using these codes accurately supports documentation of timing, outcome, and complexity of preterm labor episodes, assisting healthcare professionals and coders in identifying conditions like early or threatened labor and premature birth scenarios.
