Desmoid tumor, intraabdominal

This code represents a desmoid tumor, which is a rare, locally aggressive, non-metastatic fibrous tumor, specifically located within the abdominal cavity. These tumors arise from musculoaponeurotic structures and can infiltrate surrounding tissues, though they do not typically spread to distant sites.

Use this code when documentation clearly identifies a desmoid tumor confirmed to be situated within the intraabdominal space. This diagnosis is often supported by imaging studies (e.g., CT, MRI) and biopsy results confirming the histological characteristics of a desmoid tumor.

• Ensure the documentation specifies "intraabdominal" to differentiate from desmoid tumors in other anatomical sites.
• Do not confuse with other benign or malignant abdominal masses; pathology reports are crucial for definitive diagnosis.
• Consider sequencing with codes for any associated conditions, such as Gardner syndrome, if applicable.
