2026 ICD-10-CM Diagnosis Code C44.19 – Other specified malignant neoplasm of skin of eyelid, including canthus
What it is
C44.19 identifies a malignant skin tumor on the eyelid or canthus that does not fit a more specific eyelid skin cancer code. Use it when documentation names another specified malignant neoplasm of this skin location.
Clinical signs
Findings may include a persistent eyelid lesion, ulceration, bleeding, crusting, or a nonhealing growth. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a malignant neoplasm of the eyelid skin, including the canthus, and does not specify a more exact histology or site code. It also fits cases labeled “other specified” malignant skin cancer of this area. Check documentation for laterality and pathology details.
Do not use for
Do not use this code for benign eyelid lesions, carcinoma in situ, or malignant tumors of the eyelid margin if another more specific code is documented. Do not guess the diagnosis; check documentation.
Coding tip
Capture the exact anatomic site and any documented histology before assigning C44.19.
