ICD-10 Code D23 – Other benign neoplasms of skin (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23 – Other benign neoplasms of skin
What it is
D23 is the ICD-10-CM category for benign, noncancerous skin growths that do not fit a more specific skin neoplasm code. Use it when documentation identifies an other benign neoplasm of skin without naming a precise type.
Clinical signs
These lesions are usually localized, slow-growing skin masses or bumps that appear clinically benign. Clinical features vary; refer to documentation for the lesion type, site, and whether the diagnosis was confirmed by exam or pathology.
When to use this code
Use D23 when the provider documents a benign skin neoplasm and does not specify a more exact ICD-10 code. It is appropriate for charted terms such as “benign skin tumor” or “other benign neoplasm of skin.” Check the note for the specific anatomic site and any pathology results.
Do not use for
Do not use D23 for malignant skin tumors, premalignant lesions, or inflammatory skin conditions. If the documentation names a specific benign lesion with its own code, code that diagnosis instead.
Coding tip
Code to the most specific lesion documented; if the record only says benign skin neoplasm, D23 is the correct general choice.
