Abnormalities of forces of labor (O62) ICD-10-CM
The O62 code range covers abnormalities of forces of labor with 8 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.

Clinical Terms in This Code Range

Uterine Inertia
Failure of the UTERUS to contract with normal strength, duration, and intervals during childbirth (LABOR, OBSTETRIC). It is also called uterine atony.
About the O62 Code Range
ICD-10 codes O62 and its subcategories are used to classify various abnormalities of forces of labor encountered during childbirth. These codes specifically document issues related to uterine contractions that affect the progress and quality of labor.
The code O62.0 addresses primary inadequate contractions, also known as primary uterine inertia or failure of cervical dilation due to weak contractions. O62.1 refers to secondary uterine inertia, which captures arrested labor phases often requiring oxytocin to stimulate contractions. O62.2 covers other uterine inertia, including hypotonic or absent contractions causing slow or halted labor. Rapid labor stages fall under O62.3 precipitate labor, while O62.4 describes hypertonic, incoordinate, and prolonged contractions, which can cause labor dystocia due to overly strong, uncoordinated uterine activity. O62.8 includes miscellaneous uterine contraction problems such as irregular or excessive contractions. When the abnormal force of labor is unspecified, O62.9 is applied.
These ICD-10 codes provide precise identification of labor issues for documentation, billing, and clinical communication, helping providers and coders address conditions like hypotonic uterine dysfunction, inefficient uterine activity, or precipitate labor accurately.
