CPT® Code 58900

The procedure described by CPT® Code 58900 refers to a biopsy of the ovary, which can be performed on one or both ovaries, hence the term unilateral or bilateral. This procedure is classified as a separate procedure, indicating that it is distinct from other surgical interventions that may be performed concurrently. During the biopsy, the physician makes an incision through the skin and subcutaneous tissue of the abdomen to access the ovaries. The process involves careful dissection through various layers of abdominal tissue, including the anterior rectus fascia and the rectus muscles, to reach the peritoneal cavity. Once the ovaries are visualized, any lesions present are identified, and tissue samples are collected for laboratory analysis. This procedure is critical for diagnosing conditions affecting the ovaries, such as tumors or cysts, and is performed with the intent of obtaining accurate histological information to guide further management. After the biopsy, the abdominal layers are meticulously closed to ensure proper healing and minimize complications.
