CPT code 58943 covers abdominal oophorectomy with staging procedures for ovarian, tubal, or primary peritoneal cancer, including removal of part or all of one or both ovaries, lymph node biopsies, and tissue sampling. This surgical oncology procedure is clinically significant due to its role in cancer staging, cytoreduction, and guiding subsequent systemic therapy; it is performed in hospital operating rooms and commonly requires inpatient care and multidisciplinary perioperative management. Nationally, such procedures affect surgical oncology resource use, hospital throughput, and efforts to standardize cancer-directed surgical care. Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing profile of the code, context on where the service is typically provided, common modifiers and billing considerations supplied in the input, and guidance on where to find additional coding relationships.
