Benign neoplasm of soft tissue of retroperitoneum and peritoneum (D20)

The ICD-10 codes D20, D20.0, and D20.1 classify benign tumors located in the soft tissues of the retroperitoneum and peritoneum. These codes are used specifically to identify noncancerous growths in these areas of the abdomen.

The ICD-10 code D20 refers broadly to benign neoplasms of soft tissue in the retroperitoneum and peritoneum. More specifically, D20.0 is assigned for benign tumors in the retroperitoneum, which include various tissues such as the periadrenal, perirenal, and retrocecal regions. Recognizing terms like "benign neoplasm of retroperitoneum" or "tumor of peritoneum and retroperitoneum" helps coders accurately use this code. Meanwhile, D20.1 applies to benign growths in the peritoneum, involving structures like the omentum, mesocolon, and rectouterine pouch. Synonyms such as "benign neoplasm of the peritoneum" or "neoplasm of the mesentery" guide in assigning this code correctly. These codes assist healthcare professionals and coders in precisely documenting benign soft tissue tumors in these abdominal regions for clinical and billing purposes.
