Malignant neoplasm of oropharynx (C10) ICD-10-CM
The C10 code range covers malignant neoplasm of oropharynx with 8 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
- code to identify:
- alcohol abuse and dependence F10
- exposure to environmental tobacco smoke Z77.22
- exposure to tobacco smoke in the perinatal period P96.81
- history of tobacco dependence Z87.891
- occupational exposure to environmental tobacco smoke Z57.31
- tobacco dependence F17
- tobacco use Z72.0
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the C10 Code Range
Cancer in the oropharynx, a part of the throat, may start there or spread there from another site. C10 sits within the group for cancers of the lip, mouth and throat.
The subdivisions distinguish the vallecula (C10.0), front of the epiglottis (C10.1), and side or back wall of the oropharynx (C10.2, C10.3). Separate codes identify the branchial cleft (C10.4), overlapping sites (C10.8), and an unspecified oropharyngeal site (C10.9).
