Primary inadequate contractions

This code represents a labor complication characterized by uterine contractions that are insufficient in strength, frequency, or duration to achieve cervical dilation and effacement necessary for the progression of labor. It signifies a primary dysfunction of the uterus's ability to contract effectively from the onset of labor.

Apply this code when documentation clearly indicates that the patient's labor has begun but the uterine contractions are inherently weak or ineffective from the start, leading to a failure to progress. This is typically diagnosed when the cervix is not dilating or effacing despite the presence of contractions.

• Ensure documentation specifies "primary" inadequate contractions, distinguishing it from secondary arrest of labor.
• Do not confuse with codes for prolonged labor or arrested labor if the contractions were initially adequate.
• Always sequence this code as a principal diagnosis when it is the primary reason for the encounter, followed by codes for any interventions or outcomes.
