ICD-10 Code D48.114 – Desmoid tumor, intraabdominal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D48.114 – Desmoid tumor, intraabdominal
What it is
D48.114 identifies an intraabdominal desmoid tumor, also called aggressive fibromatosis, arising within the abdomen. It is a locally aggressive soft tissue tumor that does not metastasize.
Clinical signs
Clinical features vary; refer to documentation. Patients may have an abdominal mass, pain, bowel symptoms, or findings on imaging that suggest a fibrous, infiltrative lesion.
When to use this code
Use this code when the provider documents a desmoid tumor located in the intraabdominal region, such as the mesentery or related abdominal soft tissues. It may also apply when imaging or pathology confirms the site and diagnosis. If the record only says desmoid tumor without location, check documentation.
Do not use for
Do not use this code for desmoid tumors in other anatomic sites, such as abdominal wall or extra-abdominal locations. Do not use it for unspecified soft tissue masses or other benign neoplasms without confirmation.
Coding tip
Code the documented anatomic site carefully; intraabdominal location is what makes D48.114 specific.
