ICD-10 Code C44.1922 – Other specified malignant neoplasm of skin of right lower eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.1922 – Other specified malignant neoplasm of skin of right lower eyelid, including canthus
What it is
This code identifies a malignant skin tumor on the right lower eyelid, including the canthus, when the documentation specifies a type not named elsewhere in ICD-10-CM. Use it for a confirmed skin cancer affecting that exact site.
Clinical signs
Findings may include a persistent eyelid lesion, growth, ulceration, bleeding, crusting, or a nonhealing area. Clinical features vary; refer to documentation for the exact histologic type and location.
When to use this code
Use this code when the provider documents a malignant neoplasm of the skin on the right lower eyelid or canthus and the diagnosis is not captured by a more specific skin cancer code. It is appropriate after pathology or clear clinical documentation confirms malignancy. If the record only says “eyelid cancer,” check documentation for laterality and site.
Do not use for
Do not use this code for benign eyelid lesions, premalignant changes, or unspecified eyelid cancers without the required detail. Check documentation if the lesion is on a different eyelid, the left side, or a non-skin primary tumor.
Coding tip
Verify right-sided lower eyelid and canthus documentation before assigning C44.1922.
