ICD-10 Code D23.4 – Other benign neoplasm of skin of scalp and neck (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23.4 – Other benign neoplasm of skin of scalp and neck
What it is
D23.4 identifies a noncancerous skin growth located on the scalp or neck. Use it when the documentation states a benign neoplasm of skin in this anatomic area.
Clinical signs
Findings usually describe a localized skin lesion such as a raised, slowly growing, or well-circumscribed mass. Clinical features vary; refer to documentation for the exact appearance and whether pathology confirmed benign behavior.
When to use this code
Use D23.4 when the provider documents a benign neoplasm of the skin on the scalp or neck, including a lesion described as benign and nonmalignant. This code fits confirmed diagnoses and documented assessments awaiting definitive removal or pathology. If the site is different, code the more precise location.
Do not use for
Do not use this code for malignant skin tumors, uncertain masses, or inflammatory skin lesions. Check documentation if the lesion is not clearly identified as a benign neoplasm of the scalp or neck.
Coding tip
Match both the benign nature and the exact anatomic site before assigning D23.4.
