ICD-10 Code C69.01 – Malignant neoplasm of right conjunctiva (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.01 – Malignant neoplasm of right conjunctiva
What it is
C69.01 identifies a malignant tumor arising in the conjunctiva of the right eye. Use it when the record specifies cancer in that exact site.
Clinical signs
Clinical features may include a visible conjunctival mass, persistent redness, irritation, or a lesion that does not resolve. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents primary malignancy of the right conjunctiva, including biopsy-confirmed or clinically diagnosed disease. It is appropriate when the record clearly states the right-sided conjunctival site. If the laterality or exact diagnosis is unclear, check documentation.
Do not use for
Do not use this code for benign conjunctival lesions, nonspecific eye redness, or malignancy in another eye structure. If the chart does not confirm conjunctival cancer on the right, check documentation.
Coding tip
Verify both malignancy and laterality in the pathology or provider note before assigning C69.01.
