ICD-10 Code D23.9 – Other benign neoplasm of skin, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23.9 – Other benign neoplasm of skin, unspecified
What it is
D23.9 identifies a benign skin growth when the site is not specified. Use it for a noncancerous lesion documented as an “other” benign neoplasm of skin, but without a more precise location.
Clinical signs
These lesions are usually localized, slow-growing skin masses or nodules. Clinical features vary; refer to documentation, and confirm that the provider describes the lesion as benign rather than suspicious or malignant.
When to use this code
Use D23.9 when the record documents a benign neoplasm of skin and does not identify the exact anatomic site. It is appropriate when the provider uses nonspecific wording such as “other benign skin lesion” and no better code is available. Check documentation if the diagnosis is uncertain.
Do not use for
Do not use this code for malignant skin tumors, premalignant lesions, or inflammatory skin disorders. Also avoid it when the specific body site is documented and a more precise D23 code applies.
Coding tip
Before assigning D23.9, verify that the lesion is benign and that the chart does not name a specific skin location.
