ICD-10 Code D23.22 – Other benign neoplasm of skin of left ear and external auricular canal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23.22 – Other benign neoplasm of skin of left ear and external auricular canal
What it is
This code identifies a benign, noncancerous growth of the skin on the left ear or in the external auricular canal. It is used when the lesion is documented as benign but does not fit a more specific skin neoplasm category.
Clinical signs
Findings may include a visible or palpable skin lesion on the left ear, with slow growth and no evidence of invasion. Clinical features vary; refer to documentation for size, appearance, and whether the lesion is symptomatic.
When to use this code
Use this code when the provider documents a benign skin neoplasm on the left ear or external auricular canal. It may apply after exam, biopsy, or excision when the diagnosis is recorded as other benign neoplasm of skin. Check documentation if the site or behavior is unclear.
Do not use for
Do not use this code for malignant, premalignant, or unspecified skin lesions. If the lesion is described as cyst, wart, polyp, or another named condition, code the documented diagnosis instead.
Coding tip
Verify both the benign behavior and the left-sided ear site before assigning D23.22.
