ICD-10 Code D23.70 – Other benign neoplasm of skin of unspecified lower limb, including hip (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D23.70 – Other benign neoplasm of skin of unspecified lower limb, including hip
What it is
This code identifies a noncancerous skin growth on the lower limb or hip when the site is not further specified. Use it for benign lesions documented as skin neoplasms, not for inflammatory or malignant conditions.
Clinical signs
Clinical features vary; refer to documentation. Benign skin neoplasms are typically described as a localized, well-defined lesion or lump without evidence of invasion or metastasis.
When to use this code
Use D23.70 when the provider documents a benign neoplasm of skin on the lower limb or hip and does not name a more specific subsite. It is appropriate when pathology, exam, or assessment supports a benign skin tumor. If the record is vague, check documentation before assigning this code.
Do not use for
Do not use this code for malignant skin tumors, premalignant lesions, or non-neoplastic skin conditions such as cysts, warts, or dermatitis. If the lesion is on a different body site, select the code that matches the documented location.
Coding tip
Verify both the benign nature and the lower-limb/hip location in the note before coding.
