Partial doubling of uterus

This code signifies a congenital anomaly where the uterus is partially duplicated, meaning it has two distinct cavities or horns that are not fully separated. This malformation results from an incomplete fusion of the Müllerian ducts during fetal development, leading to a uterus that is bicornuate or septate.

Apply this code when documentation explicitly states a partial doubling of the uterus, such as a bicornuate uterus (uterus bicornis) or a septate uterus, identified through imaging studies (e.g., ultrasound, MRI, hysteroscopy) or surgical exploration. It is appropriate for patients presenting with reproductive issues like recurrent miscarriage, infertility, or obstetric complications attributed to this uterine anomaly.

• Differentiate carefully between partial doubling (bicornuate, septate) and complete doubling (uterus didelphys), which is coded elsewhere.
• Ensure the documentation specifies "partial" or describes a bicornuate/septate morphology to support this code.
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter, especially for surgical correction or fertility evaluations.
