Congenital torsion of ovary

This code describes a birth defect where the ovary is abnormally twisted on its pedicle, compromising its blood supply. This congenital anomaly can lead to ovarian ischemia, necrosis, and potential loss of the affected ovary if not promptly addressed.

Use this code for documented cases of ovarian torsion identified at birth or shortly thereafter, specifically attributed to a congenital malformation or abnormal attachment. Documentation should clearly indicate the congenital nature of the torsion, distinguishing it from acquired forms.

• Differentiate from acquired ovarian torsion (N83.5-), which is typically spontaneous and not due to a birth defect.
• Code any associated complications, such as ovarian necrosis or infarction, as secondary diagnoses.
• Ensure documentation explicitly states "congenital" or "present at birth" to support this specific code.
