Residual ovary syndrome

This code represents a condition where ovarian tissue remains after a hysterectomy or oophorectomy, leading to symptoms such as pelvic pain, dyspareunia, or ovarian cyst formation. It signifies the presence of functional ovarian remnants post-surgical removal of the uterus and/or ovaries.

Use this code when documentation clearly indicates symptoms attributable to residual ovarian tissue following a previous oophorectomy or hysterectomy. Supporting documentation should include a history of pelvic surgery and clinical findings consistent with functioning ovarian remnants.

• Differentiate from ovarian remnant syndrome (N83.8), which implies a larger, more symptomatic remnant.
• Ensure documentation specifies residual tissue rather than a completely missed ovary.
• Sequence as a secondary diagnosis if the primary reason for the encounter is a complication directly caused by the residual tissue (e.g., ovarian cyst).
