Buddy Documentation Tip

HCC Buddy guidance

Query the provider to identify which specific salivary gland is affected (parotid, submandibular, or sublingual) to assign a more specific code (D11.0, D11.7, or D11.8) rather than using the unspecified code D11.9

Ensure documentation distinguishes between benign neoplasm (D11.9) and malignant neoplasm of salivary glands (C07-C08 codes) to avoid miscoding

What This Code Means

D11.9 is the ICD-10-CM diagnosis code for benign neoplasm of major salivary gland, unspecified. A benign (non-cancerous) tumor that has developed in one of the major salivary glands, but the specific gland location has not been documented. Major salivary glands include the parotid, submandibular, and sublingual glands located in and around the mouth and jaw area. D11.9 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).

D11.9 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D11.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Query the provider to identify which specific salivary gland is affected (parotid, submandibular, or sublingual) to assign a more specific code (D11.0, D11.7, or D11.8) rather than using the unspecified code D11.9
•Ensure documentation distinguishes between benign neoplasm (D11.9) and malignant neoplasm of salivary glands (C07-C08 codes) to avoid miscoding
