Code Classification
C02.9 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of tongue, unspecified. The code C02.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code C02.9 might also be used to specify conditions or terms like local recurrence of malignant tumor of tongue, malignant melanoma of tongue, malignant tumor of tongue, metastasis from malignant tumor of tongue, primary malignant neoplasm of tongue , squamous cell carcinoma of oral mucous membrane, etc.
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: lingual NEC [See Also: Neoplasm, tongue] or tongue .
Unspecified diagnosis codes like C02.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
Approximate Synonyms

Table of Neoplasms
The code C02.9 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.
Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients
Oral Cancer
Oral cancer can form in any part of the mouth. Most oral cancers begin in the flat cells that cover the surfaces of your mouth, tongue, and lips. Anyone can get oral cancer, but the risk is higher if you are male, use tobacco, drink lots of alcohol, have HPV, or have a history of head or neck cancer. Frequent sun exposure is also a risk factor for lip cancer.
Symptoms of oral cancer include
- White or red patches in your mouth
- A mouth sore that won't heal
- Bleeding in your mouth
- Loose teeth
- Problems or pain with swallowing
- A lump in your neck
- An earache
Tests to diagnose oral cancer include a physical exam, endoscopy, biopsy, and imaging tests. Oral cancer treatments may include surgery, radiation therapy, and chemotherapy. Some patients have a combination of treatments.
