ICD-10 Code D36 – Benign neoplasm of other and unspecified sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D36 – Benign neoplasm of other and unspecified sites
What it is
D36 is the category for benign tumors in sites not named by a more specific ICD-10 code. These growths are noncancerous, but the exact tissue or location must still be documented.
Clinical signs
Findings depend on the site and may include a localized mass, swelling, or pressure effects. Clinical features vary; refer to documentation and pathology, imaging, or exam findings when available.
When to use this code
Use D36 when the provider documents a benign neoplasm and no more specific site code is available. It may also fit when the record identifies a benign tumor but the location is described only as other or unspecified. Check documentation before assigning this code.
Do not use for
Do not use D36 for malignant neoplasms, in situ lesions, or uncertain behavior tumors. If the site is known and a more specific benign neoplasm code exists, choose that code instead.
Coding tip
Code the most specific benign neoplasm site documented; use D36 only when the record supports “other” or “unspecified” site.
