Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

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.

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the O32 range.

Breech Presentation

A malpresentation of the FETUS at near term or during OBSTETRIC LABOR with the fetal cephalic pole in the fundus of the UTERUS. There are three types of breech: the complete breech with flexed hips and knees; the incomplete breech with one or both hips partially or fully extended; the frank breech with flexed hips and extended knees.

About the O32 Code Range

The ICD-10 code O32 covers maternal care related to fetal malpresentation during pregnancy and labor, such as when the fetus is not in the normal head-down position. These codes specify conditions like unstable lie, breech presentation, transverse or oblique lie, and other uncommon fetal positions, helping healthcare providers document and manage malpresentation cases carefully.

Within this category, codes like O32.0 represent care for an unstable lie, sometimes referred to as "fetal disorder due to unstable lie before labor." For breech presentations, including frank breech or footling breech, the O32.1 codes are used, encompassing many synonyms such as "breech position of fetus" or "breech extraction." Transverse and oblique lies, also described as "shoulder presentations" or "oblique lie with antenatal problem," are coded under O32.2. Face, brow, and chin presentations—known as "mentoanterior position" or "brow delivery"—fall under O32.3. These codes also cover compound presentations and other rarer malpresentations like "asynclitism" or "knee presentation" (codes starting with O32.6 and O32.8 respectively). The unspecified category O32.9 handles malpresentation cases not otherwise classified, including multiple pregnancies with malpresentation. Using the appropriate ICD-10 code for malpresentation ensures precise tracking of maternal care challenges related to fetal positioning during pregnancy and delivery.
