ICD-10 code for preterm delivery

The ICD-10-CM code for preterm delivery is O60.10 (Preterm labor with preterm delivery, unspecified trimester).

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.
