Hyperstimulation of ovaries

This code signifies ovarian hyperstimulation syndrome (OHSS), a potentially serious iatrogenic complication primarily associated with assisted reproductive technologies (ART) such as in vitro fertilization (IVF). It results from an exaggerated systemic response to ovarian stimulation medications, leading to enlarged ovaries, fluid shifts, and various systemic symptoms.

Use this code when documenting a patient experiencing symptoms of OHSS, ranging from mild abdominal discomfort and bloating to severe cases involving ascites, pleural effusions, electrolyte imbalances, and thromboembolic events. Documentation should clearly indicate a history of ovarian stimulation, typically for fertility treatment, and the presenting signs and symptoms consistent with hyperstimulation.

• Differentiate from other ovarian disorders like polycystic ovarian syndrome (PCOS) or ovarian cysts, which have different etiologies.
• Always sequence this code as a secondary diagnosis when the primary reason for the encounter is related to the management of the OHSS complications (e.g., paracentesis for ascites).
• Ensure the medical record explicitly links the hyperstimulation to fertility treatment or ovarian stimulation protocols.
