Corpus luteum cyst of right ovary

This code identifies a benign, fluid-filled sac that forms on the right ovary after an egg has been released from the follicle. It is a common type of functional ovarian cyst, typically resolving spontaneously within a few menstrual cycles.

Apply this code when documentation specifies a corpus luteum cyst located on the right ovary. Supporting documentation includes ultrasound reports, physician notes detailing physical examination findings, or surgical pathology reports confirming the diagnosis and laterality.

• Ensure laterality is clearly documented as "right ovary" to avoid unspecified ovarian cyst codes.
• Distinguish from other types of ovarian cysts, such as follicular cysts (N83.0-) or other specified noninflammatory disorders of the ovary (N83.8-).
• Do not use for cysts that are explicitly stated as hemorrhagic, as those have a separate code (N83.211).
