ICD-10 Code C69.5 – Malignant neoplasm of lacrimal gland and duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.5 – Malignant neoplasm of lacrimal gland and duct
What it is
This code identifies a malignant tumor arising in the lacrimal gland or lacrimal duct. Use it when documentation confirms cancer in the tear-producing or tear-draining structures of the eye.
Clinical signs
Clinical features may include a palpable orbital mass, eyelid swelling, pain, or displacement of the eye. Clinical features vary; refer to documentation and pathology or imaging when available.
When to use this code
Use C69.5 when the provider documents primary malignancy of the lacrimal gland or lacrimal duct. It also fits confirmed malignant neoplasm involving these structures, even if the note describes the tumor as an eye adnexal cancer. Verify laterality and site details if recorded.
Do not use for
Do not assign this code for benign lacrimal lesions, inflammatory disorders, or unspecified orbital tumors. Check documentation if the record only says “eye cancer” without a specific lacrimal gland or duct site.
Coding tip
Code the exact lacrimal site stated by the provider and query if the documentation is vague.
