ICD-10 Code C44.60 – Unspecified malignant neoplasm of skin of upper limb, including shoulder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.60 – Unspecified malignant neoplasm of skin of upper limb, including shoulder
What it is
C44.60 identifies a malignant skin tumor on the upper limb, including the shoulder, when the exact skin site is not further specified. Use it when documentation confirms skin cancer but does not name a more precise subsite.
Clinical signs
Clinical features vary; refer to documentation. Skin cancers may appear as a persistent lesion, nonhealing sore, changing growth, or abnormal pigmentation on the arm or shoulder.
When to use this code
Use this code when the provider documents a malignant neoplasm of skin on the upper limb or shoulder and no more specific location is stated. It also fits when the record says “skin cancer” of that region without histologic detail in the diagnosis entry. If laterality or exact subsite is available, code more specifically.
Do not use for
Do not use this code for benign skin lesions, premalignant changes, or malignant tumors arising from deeper tissues. Check documentation if the lesion is clearly described as another skin site or a different primary cancer.
Coding tip
Query for the exact anatomic site before assigning C44.60, because a more specific skin code may be available.
