ICD-10 Code D11 – Benign neoplasm of major salivary glands (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D11 – Benign neoplasm of major salivary glands
What it is
D11 identifies a noncancerous tumor arising in a major salivary gland, such as the parotid, submandibular, or sublingual gland. It is used when the lesion is documented as benign and not malignant or uncertain.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a slowly enlarging, usually painless mass in the salivary gland region, with possible facial asymmetry or local fullness on exam.
When to use this code
Use D11 when the provider documents a benign neoplasm of a major salivary gland without specifying a more exact gland site. It also fits cases confirmed by pathology or imaging as benign. If the record names the specific major salivary gland, choose the more detailed subcode.
Do not use for
Do not use D11 for malignant salivary gland tumors or for lesions documented as uncertain, unspecified, or inflammatory. Check documentation if the mass is not clearly described as benign.
Coding tip
Capture the exact gland and pathology wording when available, because D11 has more specific subcodes for site-specific reporting.
