2026 ICD-10-CM Diagnosis Code C44.709 – Unspecified malignant neoplasm of skin of left lower limb, including hip
What it is
This code identifies a malignant skin tumor on the left lower limb, including the hip, when the exact histology is not specified. Use it when the record confirms skin cancer but does not name the specific type.
Clinical signs
Clinical features vary; refer to documentation. You may see a suspicious skin lesion, nonhealing ulcer, changing growth, or biopsy-confirmed malignancy on the left lower limb or hip.
When to use this code
Use this code when the provider documents a malignant neoplasm of skin in the left lower limb, including the hip, and no more specific diagnosis is available. It is appropriate when pathology, consultation notes, or the final assessment remain nonspecific. If the site is elsewhere or the tumor type is identified, choose a more specific code.
Do not use for
Do not use this code for benign skin lesions, premalignant changes, or uncertain behavior tumors. Do not use it when the documentation identifies a different anatomic site or a specific skin cancer type.
Coding tip
Always verify laterality and the exact documented site before assigning C44.709.
