Developmental ovarian cyst

This code describes a congenital anomaly of the ovary characterized by the presence of a cyst that developed during fetal growth. These cysts are typically benign and result from abnormal development of ovarian tissue. They may be identified prenatally or postnatally.

Use this code when documentation clearly indicates a cyst of the ovary is developmental or congenital in origin. This is often supported by imaging studies (e.g., ultrasound) and clinical history, especially if identified in infancy or childhood, or if a congenital etiology is explicitly stated by the physician.

• Differentiate from acquired ovarian cysts (e.g., follicular, corpus luteum, endometrioma), which are coded elsewhere.
• Ensure the documentation specifies "developmental" or "congenital" to support this specific code.
• Do not use for unspecified ovarian cysts; query the provider for clarification if the etiology is not documented.
