ICD-10 Code C44.192 – Other specified malignant neoplasm of skin of right eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C44.192 – Other specified malignant neoplasm of skin of right eyelid, including canthus
What it is
This code identifies a malignant skin tumor on the right eyelid or canthus that does not fit a more specific skin cancer category. Use it when the record clearly states a qualifying malignant neoplasm and laterality.
Clinical signs
Findings may include a persistent eyelid or canthal lesion, ulceration, crusting, bleeding, or a nonhealing mass. Clinical features vary; refer to documentation and pathology when available.
When to use this code
Use this code when the provider documents an “other specified” malignant skin neoplasm involving the right eyelid, including the inner or outer canthus. It is appropriate when the site and right-sided laterality are confirmed, but the tumor type is not captured by a more specific code.
If the note only says “skin cancer” or the pathology is unclear, check documentation before assigning this code. Confirm whether the lesion is truly on the eyelid/canthus skin and not another periocular structure.
Do not use for
Do not use this code for benign eyelid lesions, unspecified skin malignancies, or cancers of the conjunctiva or other non-skin eye structures. Check documentation if the site or histology is not clearly stated.
Coding tip
Verify both the malignant nature and the right eyelid/canthus location in the operative note, pathology report, or assessment.
