ICD-10 Code C69.52 – Malignant neoplasm of left lacrimal gland and duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.52 – Malignant neoplasm of left lacrimal gland and duct
What it is
C69.52 identifies a malignant tumor arising in the left lacrimal gland or lacrimal duct. Use it when the record specifically documents cancer in the left tear-producing or drainage structures.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include a mass in the lacrimal region, swelling near the outer upper eyelid, tearing, or local pain.
When to use this code
Use this code when the provider documents primary malignancy of the left lacrimal gland or duct. It also fits confirmed cancer noted as arising from those left-sided structures. If the chart only says “lacrimal mass” or laterality is unclear, check documentation before coding.
Do not use for
Do not use C69.52 for benign lacrimal lesions, infections, or nonspecific eye swelling. Do not assign it when the tumor site is not documented as left lacrimal gland or duct.
Coding tip
Verify both malignancy and laterality in the pathology or assessment note before assigning C69.52.
