ICD-10 Code D22.11 – Melanocytic nevi of right eyelid, including canthus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D22.11 – Melanocytic nevi of right eyelid, including canthus
What it is
This code identifies a benign melanocytic nevus located on the right eyelid, including the canthus. It is used for a mole-like lesion made of melanocytes, not a malignant skin cancer.
Clinical signs
Findings usually include a localized pigmented or flesh-colored eyelid lesion that is stable and well circumscribed. Clinical features vary; refer to documentation if the appearance, size, or changes are not clearly described.
When to use this code
Use D22.11 when the provider documents a melanocytic nevus specifically on the right eyelid or right canthus. Apply it for benign lesions confirmed on exam, history, or pathology when the anatomic site is clearly the right side.
Choose this code when the record distinguishes the lesion from other eyelid growths, such as cysts, papillomas, or malignant tumors. If laterality is missing or the site is uncertain, check documentation before coding.
Do not use for
Do not use this code for malignant melanoma, atypical melanocytic lesions, or nonspecific eyelid masses. It is also incorrect when the lesion is on the left eyelid or laterality is not documented.
Coding tip
Verify both laterality and exact eyelid location, including canthus, before assigning D22.11.
