Benign neoplasm of left lacrimal gland and duct

This diagnosis code signifies the presence of a non-cancerous growth originating in the left lacrimal gland or its associated ductal system. These benign neoplasms are typically slow-growing and do not metastasize, but can cause symptoms due to mass effect on surrounding ocular structures.

Use this code when documentation clearly indicates a benign tumor affecting the lacrimal gland or duct on the patient's left side. This is appropriate for initial diagnosis, follow-up, or treatment of such a lesion. Supporting documentation would include pathology reports confirming benignity, imaging studies localizing the mass, and physician notes specifying the left side.

• Ensure laterality is explicitly documented as "left" to avoid coding errors.
• Distinguish from malignant neoplasms of the lacrimal gland (C69.52) based on pathology.
• Do not use for inflammatory conditions of the lacrimal gland (e.g., dacryoadenitis) unless a benign neoplasm is also present.
