ICD-10 Code D11.0 – Benign neoplasm of parotid gland (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D11.0 – Benign neoplasm of parotid gland
What it is
D11.0 identifies a noncancerous tumor arising in the parotid gland, the largest salivary gland near the jaw and ear. Use it when documentation states a benign parotid gland neoplasm.
Clinical signs
Clinical features vary; refer to documentation. Commonly, a parotid mass is noted, sometimes with slow growth or facial asymmetry, but the diagnosis depends on pathology or clear clinical assessment.
When to use this code
Use this code when the record specifically documents a benign neoplasm of the parotid gland, including a confirmed benign tumor of that gland. It also fits cases where the provider names a benign parotid mass as the diagnosis. If the site is uncertain or malignancy is suspected, check documentation before coding.
Do not use for
Do not use D11.0 for malignant salivary gland tumors, parotitis, cysts, or nonspecific swelling without a documented benign neoplasm. Check documentation if the pathology report is unclear.
Coding tip
Code the documented gland and behavior exactly; if the note says “benign parotid tumor,” D11.0 is the appropriate choice.
