ICD-10 Code D31.52 – Benign neoplasm of left lacrimal gland and duct (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.52 – Benign neoplasm of left lacrimal gland and duct
What it is
D31.52 identifies a noncancerous growth in the left lacrimal gland or duct. It means the lesion is benign, but it still may need evaluation because it can affect tear drainage or nearby structures.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a localized mass, tearing, swelling near the inner eye, or incidental discovery on imaging or exam.
When to use this code
Use this code when the provider documents a benign neoplasm specifically in the left lacrimal gland or duct. It is appropriate for confirmed benign tumors, whether found during workup for eye symptoms or incidentally. Code only when laterality and benign behavior are clear.
Do not use for
Do not use it for malignant, uncertain, or unspecified neoplasms, or when the record does not identify the left side. Check documentation if the lesion is inflammatory, cystic, or otherwise not described as a benign neoplasm.
Coding tip
Verify both laterality and benign behavior in the note before assigning D31.52.
