About O60.10

O60.10 is the ICD-10-CM diagnosis code for preterm labor with preterm delivery, unspecified trimester. It belongs to category O60 (preterm labor), block O60-O77 (complications of labor and delivery) and chapter 15 (pregnancy, childbirth and the puerperium). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

Within O60.1, choose O60.10 (unspecified trimester) only when documentation doesn't support a more specific option: second trimester with preterm delivery second trimester (O60.12), second trimester with preterm delivery third trimester (O60.13) and third trimester with preterm delivery third trimester (O60.14).

Codes in this range require a 7th character: 0 for not applicable or unspecified, 1 for fetus 1, 2 for fetus 2, 3 for fetus 3, 4 for fetus 4, 5 for fetus 5 and 1 more. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

7th character

One of the following 7th characters is to be assigned to each code under subcategory O60.1. 7th character 0 is for single gestations and multiple gestations where the fetus is unspecified. 7th characters 1 through 9 are for cases of multiple gestations to identify the fetus for which the code applies. The appropriate code from category O30, Multiple gestation, must also be assigned when assigning a code from subcategory O60.1 that has a 7th character of 1 through 9.
