Other congenital malformation of ovary

This code signifies a congenital structural anomaly of the ovary that is not otherwise specified or categorized by more specific ICD-10-CM codes. It encompasses a range of developmental defects of the female gonad present at birth, excluding agenesis, hypoplasia, or dysgenesis when those specific terms are documented.

Use this code when documentation indicates a congenital malformation of the ovary, such as an accessory ovary, duplicated ovary, or other unspecified structural defect, and no more specific code is available. Supporting documentation should clearly state the congenital nature and the specific type of malformation if known, or simply "other congenital malformation of ovary."

• Ensure the documentation explicitly states "congenital" to support the use of a Q code.
• Review for more specific codes within the Q50 category (e.g., Q50.0 for congenital absence, Q50.1 for congenital hypoplasia) before assigning this code.
• This code should be used when the specific type of congenital ovarian malformation is not detailed enough for a more precise code, but a malformation is clearly present.
