ICD-10 Code D48.118 – Desmoid tumor of other site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D48.118 – Desmoid tumor of other site
What it is
D48.118 identifies a desmoid tumor located in a site other than the more specific categories in ICD-10-CM. It is a locally aggressive soft tissue tumor that does not metastasize, but it can invade nearby structures.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a firm, slowly enlarging mass and pain or functional limitation when the tumor compresses adjacent tissue.
When to use this code
Use this code when the provider documents a desmoid tumor and the site is not captured by a more specific ICD-10-CM code. Apply it for pathology-confirmed or clinically documented desmoid tumor in an unspecified “other site” location. Check documentation if the record names a more precise anatomic site.
Do not use for
Do not use this code if the lesion is documented in a more specific desmoid tumor category. Do not assign it when the diagnosis is another benign, malignant, or uncertain soft tissue mass without explicit desmoid tumor documentation.
Coding tip
Confirm the exact tumor site in the operative note, pathology report, or assessment before assigning D48.118.
