ICD-10 Code C69.51 – Malignant neoplasm of right lacrimal gland and duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.51 – Malignant neoplasm of right lacrimal gland and duct
What it is
C69.51 identifies a malignant tumor arising in the right lacrimal gland or lacrimal duct. Use it when documentation specifies cancer in that right-sided tear-producing or tear-draining structure.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings may include a mass near the outer upper eyelid, swelling, pain, tearing, or displacement of the eye.
When to use this code
Use this code when the provider documents a primary malignant neoplasm of the right lacrimal gland or duct. It also fits pathology, imaging, or operative notes that clearly localize the tumor to the right side.
If laterality is stated as right, you should not default to an unspecified code. Check documentation when the site is described only as orbital, eyelid, or lacrimal without confirming gland or duct involvement.
Do not use for
Do not use this code for benign lacrimal lesions, inflammatory disease, or tumors of the left or unspecified lacrimal gland or duct. Check documentation if the record is unclear.
Coding tip
Confirm both malignancy and right-sided lacrimal location in the record before assigning C69.51.
