ICD-10 Code D48.115 – Desmoid tumor of upper extremity and shoulder girdle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D48.115 – Desmoid tumor of upper extremity and shoulder girdle
What it is
This code identifies a desmoid tumor, also called aggressive fibromatosis, located in the upper extremity or shoulder girdle. It is a locally invasive soft tissue tumor that does not spread to distant sites.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a firm, enlarging mass in the arm, shoulder, or nearby soft tissues, sometimes with pain, stiffness, or limited motion from local extension.
When to use this code
Use D48.115 when the provider documents a desmoid tumor specifically involving the upper extremity or shoulder girdle. Code it from imaging, pathology, or operative documentation when the anatomic site is clear.
Do not assume the site from a general soft tissue mass or fibromatosis diagnosis. If the record only says desmoid tumor without location, check documentation before assigning this code.
Do not use for
Do not use this code for benign lipoma, sarcoma, or other soft tissue tumors. If the tumor is documented in a different body site, select the site-specific code instead.
Coding tip
Always verify both the diagnosis and the exact anatomic location; site specificity is essential for correct code selection.
