Re: Codes O60.12-14 (different trimesters)

Hello, can someone explain to me descriptions in codes O62.12-14?

My basic understanding of trimesters are:

First Trimester, first to third months, 1st to 13th weeks
Second Trimester, fourth to sixth months, 14th to 26th weeks
Third Trimester, seventh to ninth months, 27th to 40th weeks

So if the patient goes into labor with delivery on her 35th week, I would use O62.14 Preterm labor third trimester with preterm delivery third trimester?

What I'm not understanding is the description repeating the trimester.

Example:
O62.12 Preterm labor second trimester with preterm delivery second trimester
O62.13 Preterm labor second trimester with preterm delivery third trimester
O62.14 Preterm labor third trimester with preterm delivery third trimester

Please help!

Thank you in advance!

Marissa

According to ICD guidelines:

1st trimester- less than 14 weeks 0 days
2nd trimester- 14 weeks 0 days to less than 28 weeks 0 days
3rd trimester- 28 weeks 0 days until delivery

Also the guidelines for section O60 state: Includes: onset (spontaneous) of labor before 37 completed weeks of gestation

So O60.14X0 - O60.14X9 depending on how many fetuses.
