ICD-10 Code D23.5 – Other benign neoplasm of skin of trunk (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23.5 – Other benign neoplasm of skin of trunk
What it is
D23.5 identifies a noncancerous skin growth located on the trunk, such as the chest, back, or abdomen. It is used when the lesion is benign but does not fit a more specific skin-neoplasm code.
Clinical signs
These lesions are usually localized, slow-growing, and well circumscribed. Clinical features vary; refer to documentation, and confirm the lesion is benign rather than suspicious for malignancy.
When to use this code
Use this code when the provider documents a benign neoplasm of skin on the trunk and no more specific histologic or anatomic code applies. It may support biopsy, excision, or follow-up documentation for a confirmed benign lesion. Check documentation if the site is described only broadly.
Do not use for
Do not use D23.5 for malignant skin tumors, premalignant lesions, or benign lesions on other body sites. If the record names a more specific benign skin neoplasm, code that instead.
Coding tip
Match the documented anatomic site carefully; trunk codes are not interchangeable with codes for face, scalp, limbs, or other specified locations.
