Follicular cyst of left ovary

This diagnosis code signifies a benign, fluid-filled sac that forms on the surface of the left ovary during the menstrual cycle. It arises when a follicle fails to rupture and release an egg, continuing to grow instead. These cysts are typically asymptomatic and often resolve spontaneously.

Apply this code when documentation explicitly states a follicular cyst is present on the left ovary. This is commonly identified during pelvic ultrasound or other imaging studies performed for gynecological symptoms or routine examinations. Support for this code includes imaging reports and physician notes confirming the location and type of ovarian cyst.

• Ensure the documentation specifies "follicular" and not another type of ovarian cyst (e.g., corpus luteum, endometrioma).
• Verify the laterality is clearly documented as "left ovary" to avoid coding an unspecified or right-sided cyst.
• Do not use this code for functional cysts that are not explicitly identified as follicular in nature.
