ICD-10 Code D17.5 – Benign lipomatous neoplasm of intra-abdominal organs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D17.5 – Benign lipomatous neoplasm of intra-abdominal organs
What it is
D17.5 identifies a benign fat-cell tumor located in an intra-abdominal organ. It means the growth is noncancerous, but its exact site inside the abdomen should be documented.
Clinical signs
Clinical features vary; refer to documentation. These tumors may be found incidentally on imaging or during surgery, and they can cause symptoms only if they compress nearby structures.
When to use this code
Use D17.5 when the provider documents a benign lipomatous neoplasm arising in an intra-abdominal organ, such as an organ within the peritoneal cavity. Code it from the confirmed diagnosis, not from a nonspecific abdominal mass alone.
If the record only says “lipoma” without location, check documentation for the exact site. You may need a different code if the lesion is clearly in another anatomic area.
Do not use for
Do not use this code for malignant liposarcoma or for lipomas outside the intra-abdominal organs. Check documentation if the finding is only a suspected mass or an unspecified abdominal lesion.
Coding tip
Verify that the note names an intra-abdominal organ and confirms benign behavior before assigning D17.5.
