ICD-10 Code C69.50 – Malignant neoplasm of unspecified lacrimal gland and duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.50 – Malignant neoplasm of unspecified lacrimal gland and duct
What it is
C69.50 identifies a malignant tumor in the lacrimal gland or duct when the exact site is not specified. Use it when documentation confirms cancer in this tear-producing area but does not name the left, right, or specific structure.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include a lacrimal mass, swelling near the inner eye, tearing, or local pain, but the diagnosis should be supported by pathology, imaging, or specialist assessment.
When to use this code
Use this code when the record states malignant neoplasm of the lacrimal gland or duct and laterality or exact subsite is not documented. It also fits when the provider confirms malignancy of this region but does not specify whether the gland or duct is involved.
If the note later identifies a more specific site or laterality, code that documented detail instead. Check documentation when the chart uses only “lacrimal tumor” or another vague term.
Do not use for
Do not use this code for benign lacrimal lesions, inflammatory disease, or tumors of other eye structures. Do not use it when the record clearly specifies a different lacrimal site or a nonmalignant diagnosis.
Coding tip
Query for laterality and exact lacrimal site before defaulting to an unspecified code.
