Benign neoplasm of lacrimal duct

This code signifies the presence of a non-cancerous growth originating within the tear drainage system. These benign tumors can affect any part of the lacrimal duct, potentially causing obstruction or other localized symptoms. The neoplasm is characterized by its non-invasive nature and lack of metastatic potential.

Assign this code when documentation clearly indicates a benign tumor affecting the lacrimal duct, lacrimal sac, or nasolacrimal duct. This is appropriate for diagnoses established through imaging, biopsy, or clinical examination confirming a non-malignant lesion. Use when the physician explicitly states "benign neoplasm" or "adenoma" of the lacrimal drainage apparatus.

• Differentiate carefully between benign and malignant neoplasms of the lacrimal system; malignant lesions require different coding.
• Ensure the documentation specifies the lacrimal duct system, not just the lacrimal gland, as these are distinct anatomical sites.
• Do not use for inflammatory conditions or cysts of the lacrimal duct unless a benign neoplasm is explicitly diagnosed.
