ICD-10 Code D48.119 – Desmoid tumor of unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D48.119 – Desmoid tumor of unspecified site
What it is
D48.119 identifies a desmoid tumor when the record does not specify the anatomic site. Desmoid tumors are locally aggressive soft tissue tumors and are not classified as malignant.
Clinical signs
Clinical features vary; refer to documentation. These tumors often present as a firm, slowly enlarging mass, sometimes with pain or limited motion if they involve nearby structures.
When to use this code
Use D48.119 when the clinician documents a desmoid tumor but does not name the site. It also fits when the note confirms a desmoid tumor and laterality or location is unavailable in the record.
If the site is documented, code the specific location instead. Check documentation for any more precise anatomic detail before assigning this unspecified code.
Do not use for
Do not use this code for other soft tissue tumors, benign neoplasms, or malignant neoplasms. Do not use it when the chart clearly identifies a specific site.
Coding tip
Query the provider for the tumor site whenever the diagnosis is incomplete, because D48.119 is only appropriate when the location remains unspecified.
