Hypoplasia of cervix

This code describes a congenital anomaly where the cervix is underdeveloped or abnormally small. This condition can impact reproductive function and may be associated with other Müllerian duct anomalies. It represents a structural defect present from birth.

Apply this code when documentation explicitly states hypoplasia of the cervix. This diagnosis is typically made through imaging studies (e.g., ultrasound, MRI) or direct visualization during gynecological examination. It is appropriate for both symptomatic and incidentally discovered cases.

• Differentiate from cervical agenesis (complete absence), which is coded elsewhere.
• Always review documentation for associated anomalies of the uterus or vagina, as these may require additional codes.
• Ensure the physician's documentation clearly specifies "hypoplasia" rather than a general term like "small cervix" without further clarification.
