ICD-10 Code C49.11 – Malignant neoplasm of connective and soft tissue of right upper limb, including shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C49.11 – Malignant neoplasm of connective and soft tissue of right upper limb, including shoulder
What it is
This code identifies a malignant soft tissue or connective tissue tumor located in the right upper limb, including the shoulder. Use it when the documentation specifies this anatomic site.
Clinical signs
Clinical features vary; refer to documentation. Soft tissue sarcomas may present as a growing mass, pain, swelling, or reduced function, but diagnosis depends on pathology and recorded site.
When to use this code
Use C49.11 when the provider documents a malignant neoplasm arising in connective or soft tissue of the right arm, forearm, upper arm, or shoulder region. It also fits when the record clearly localizes the primary tumor to that side and area. Check documentation if the site is described imprecisely.
Do not use for
Do not use this code for benign soft tissue tumors, metastatic disease to the right upper limb, or malignancies of bone, skin, or breast. Check documentation if the lesion’s origin is unclear.
Coding tip
Verify laterality and that the tumor is primary to connective or soft tissue before assigning C49.11.
