ICD-10 Code D11.9 – Benign neoplasm of major salivary gland, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code D11.9 – Benign neoplasm of major salivary gland, unspecified
What it is
This code identifies a noncancerous tumor of a major salivary gland when the specific gland is not documented. It is used for benign growths in the parotid, submandibular, or sublingual region when site detail is unavailable.
Clinical signs
Patients may have a painless, slow-growing mass near the jaw, cheek, or floor of the mouth. Clinical features vary; refer to documentation, imaging, or pathology when available.
When to use this code
Use D11.9 when the record clearly states a benign neoplasm of a major salivary gland but does not name the gland. It also fits final diagnoses after evaluation, biopsy, or excision when the site remains unspecified in the note. You should code the documented benign nature, not a suspected malignancy.
Do not use for
Do not use this code for malignant salivary gland tumors, inflammatory swelling, or cysts without a neoplasm diagnosis. If the provider documents a specific gland, check documentation for a more precise code.
Coding tip
Match the code to the provider’s final wording and verify whether the salivary gland site is specified.
