Arcuate uterus

This code describes a congenital uterine anomaly where the uterine fundus is mildly indented, giving it a heart-shaped appearance. It represents a less severe form of Mullerian duct fusion abnormality compared to septate or bicornuate uteri. While often asymptomatic, it can be associated with reproductive challenges.

Use this code when diagnostic imaging, such as ultrasound, hysterosalpingography (HSG), or MRI, confirms the presence of an arcuate uterus. It is appropriate for patients presenting with infertility, recurrent pregnancy loss, or during routine gynecological evaluation where this anomaly is identified. Documentation should clearly state "arcuate uterus" or describe the characteristic mild fundal indentation.

• Differentiate carefully from other uterine anomalies like septate uterus (Q51.1) or bicornuate uterus (Q51.2), which have more pronounced indentations or divisions.
• This code is for the anomaly itself; code any associated symptoms or complications (e.g., infertility, recurrent miscarriage) separately.
• Ensure the medical record explicitly states "arcuate uterus" or provides a clear description consistent with this diagnosis to support code assignment.
