ICD-10 Code D24.1 – Benign neoplasm of right breast (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D24.1 – Benign neoplasm of right breast
What it is
D24.1 identifies a noncancerous growth in the right breast. Use it when documentation specifically states a benign breast neoplasm on the right side.
Clinical signs
Clinical features vary; refer to documentation. A benign breast mass is often described as well-circumscribed, mobile, or found on imaging or biopsy without malignant features.
When to use this code
Use D24.1 when the provider documents a benign neoplasm of the right breast, including pathology-confirmed or clearly stated benign tumors. It may also apply when imaging or clinical assessment identifies a right breast mass and the diagnosis is documented as benign. Check documentation if laterality or benign status is unclear.
Do not use for
Do not use this code for malignant breast neoplasms, unspecified breast lesions, or cysts unless the record states a benign neoplasm. If the site is not right breast, choose the correct laterality code.
Coding tip
Always verify both benign nature and right-sided location in the provider note before assigning D24.1.
