ICD-10 Code D48.111 – Desmoid tumor of chest wall (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D48.111 – Desmoid tumor of chest wall
What it is
D48.111 identifies a desmoid tumor arising in the chest wall. It is a locally aggressive soft tissue tumor that does not spread to distant sites, but it can invade nearby structures.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include a firm, slowly enlarging chest wall mass, possible pain, and local restriction from involvement of surrounding tissues.
When to use this code
Use D48.111 when the provider documents a desmoid tumor, desmoid-type fibromatosis, or aggressive fibromatosis of the chest wall. Code it when the site is clearly the chest wall and the diagnosis is confirmed or recorded as the working diagnosis.
Check documentation if the mass is only suspected, if the site is elsewhere, or if the record uses a different soft tissue tumor diagnosis. You should match the documented anatomic location exactly.
Do not use for
Do not use this code for malignant chest wall tumors, benign lipomas, or nonspecific soft tissue masses. If the note does not clearly identify a desmoid tumor of the chest wall, check documentation.
Coding tip
Confirm both the tumor type and the chest wall site in the provider note before assigning D48.111.
