O64.1XX9 Obstructed labor due to breech presentation, other fetus

ICD-10-CM Diagnosis Code O64.1XX9 Reference

ICD-10-CM code O64.1XX9 identifies obstructed labor due to breech presentation for an other fetus. This active diagnosis concept falls under complications of labor and delivery. The terminology record classifies it as a pathologic function, and clinical literature describes breech presentation as a factor in labor management. 1 2 4

Plain-language overview

Code O64.1XX9 represents a pregnancy complication where labor is obstructed because the fetus is in a breech position, specifically applying to an other fetus rather than fetus one through five. 1 4

Breech presentation can occur in any pregnancy, and while it is more frequent before twenty-eight weeks, the prevalence decreases to three to four percent at term. 2

What this code represents

The official display label for O64.1XX9 is obstructed labor due to breech presentation, other fetus, and the terminology record assigns it a semantic type of pathologic function. 1

This diagnosis code is a narrower concept under the parent code O64.1, which broadly defines obstructed labor due to breech presentation without specifying which fetus is involved. 1 4

Coding details

Within the O64.1 category, O64.1XX9 is distinct from codes O64.1XX0 through O64.1XX5, which specify not applicable, unspecified, or individually numbered fetuses one through five. 4

The O64.1 category is nested within the O64 block for obstructed labor due to malposition and malpresentation of fetus, which itself falls under the O60 to O77 range for labor and delivery complications. 4

Documentation considerations

An obstetric clinical examination upon admission of the parturient woman aims to confirm the type of breech presentation and fetal attitude, accompanied or not by ultrasound. 2

What the sources add

While the terminology record establishes the code hierarchy and active status, clinical literature provides context on breech presentation prevalence and management considerations like external cephalic version. 1 2
