ICD-10 Code D36.9 – Benign neoplasm, unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D36.9 – Benign neoplasm, unspecified site
What it is
D36.9 identifies a noncancerous growth when the site is not specified in the record. Use it when documentation confirms a benign neoplasm but does not name the organ or tissue involved.
Clinical signs
Clinical features vary; refer to documentation. Benign neoplasms are typically localized masses or lesions without evidence of malignant behavior, and diagnosis is usually based on pathology, imaging, or operative findings.
When to use this code
Use this code when the provider documents a benign neoplasm and the exact site is unknown, omitted, or not yet determined. It may also fit when a pathology report confirms benign tissue but the final note does not identify the location. If the site is documented elsewhere, code that specific site instead.
Do not use for
Do not use D36.9 for malignant neoplasms, in situ lesions, or tumors with an unspecified behavior code that is more specific. Check documentation if the record names a precise anatomic site.
Coding tip
Before assigning D36.9, search the full chart for a more specific site description, pathology result, or operative note.
