Malignant neoplasm of parotid gland
In Malignant neoplasms of lip, oral cavity and pharynx (C00-C14), chapter 2: Neoplasms
- C07 is billable and valid on claims for FY 2027. If the record has more detail, check the other codes under C00-C14 below.
- As a secondary diagnosis it is not a CC or MCC, so it doesn't raise the MS-DRG payment.
- Counts toward HCC 21 (Lymphoma and Other Cancers) in the Medicare Advantage risk model (CMS-HCC V28).
- AHRQ's Chronic Condition Indicator classes it as chronic: expected to last 12 months or longer and to limit daily life or need ongoing care.
- 769 US deaths in 2024 had an underlying cause in category C07, per the National Vital Statistics System on CDC WONDER. Death records use WHO ICD-10, so the count is for the whole category.

Official coding guidelines
From the ICD-10-CM Official Guidelines for Coding and Reporting, FY 2027 (CMS and NCHS). Links open the PDF at the right page.
Rules for coding benign and malignant neoplasms: using the Neoplasm Table, sequencing primary and secondary sites, treatment encounters, complications, and current cancer versus personal history.
- Admission/Encounter for treatment of primary site (page 33)
- Admission/Encounter for treatment of secondary site (page 33)
- Coding and sequencing of complications (page 34)
- Primary malignancy previously excised (page 34)
- Admissions/Encounters involving antineoplastic chemotherapy, immunotherapy and radiation therapy (page 35)
- Admission/encounter to determine extent of malignancy (page 36)
- Symptoms, signs, and abnormal findings listed in Chapter 18 associated with neoplasms (page 36)
- Admission/encounter for pain control/management (page 36)

About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
Salivary Gland Cancer
Your salivary glands make saliva - sometimes called spit - and empty it into your mouth through openings called ducts. Saliva makes your food moist, which helps you chew and swallow. It helps you digest your food. It also cleans your mouth and contains antibodies that can kill germs.
