ICD-10 Code D31.62 – Benign neoplasm of unspecified site of left orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D31.62 – Benign neoplasm of unspecified site of left orbit
What it is
This code identifies a noncancerous growth in the left orbit when the exact orbital site is not specified. Use it when documentation confirms a benign orbital neoplasm but does not name the precise structure.
Clinical signs
Clinical features vary; refer to documentation. Orbital benign tumors may present with proptosis, visible swelling, or eye displacement, but the record should support the diagnosis and left-sided location.
When to use this code
Use D31.62 when the provider documents a benign neoplasm in the left orbit and does not identify a more specific orbital site. It is appropriate for confirmed benign lesions of the orbit, not for suspected masses. If the note gives a more exact orbital location, code that specific site instead.
Do not use for
Do not use this code for malignant orbital tumors, inflammatory swelling, or unspecified eye disorders. Check documentation if the lesion is not clearly benign or if laterality is missing.
Coding tip
Verify both laterality and benign nature before assigning D31.62.
