ICD-10 Code D48.112 – Desmoid tumor, intrathoracic (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D48.112 – Desmoid tumor, intrathoracic
What it is
D48.112 identifies a desmoid tumor located within the thorax. 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. Patients may have a chest mass, pain, pressure symptoms, or findings from imaging that show a thoracic soft tissue lesion.
When to use this code
Use this code when the provider documents a desmoid tumor in the intrathoracic region, such as the mediastinum, chest wall, or pleural area. Code it from confirmed clinical, imaging, or pathology documentation. If the site is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for other benign or malignant thoracic masses unless the record specifically identifies a desmoid tumor. Do not assume the site is intrathoracic without clear documentation.
Coding tip
Verify both the tumor type and the anatomic location in the note before coding.
