ICD-10 Code D48.117 – Desmoid tumor of back (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D48.117 – Desmoid tumor of back
What it is
D48.117 identifies a desmoid tumor located in the back. This is a locally aggressive soft tissue growth that does not spread to distant sites, but it can invade nearby structures.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a firm, deep mass in the back, with pain, stiffness, or limited motion depending on size and location.
When to use this code
Use this code when the provider documents a desmoid tumor, fibromatosis, or desmoid-type fibromatosis specifically in the back. It is appropriate for confirmed diagnoses on imaging, biopsy, or specialist assessment. Check documentation if the site is described more generally, such as trunk or soft tissue.
Do not use for
Do not use this code for benign skin lesions, lipoma, or unspecified soft tissue masses of the back. If the record does not clearly identify a desmoid tumor, check documentation.
Coding tip
Match the anatomic site exactly; if the back is not specified, you may need a different code.
