| ICD-10: | C01 |
| Short Description: | Malignant neoplasm of base of tongue |
| Long Description: | Malignant neoplasm of base of tongue |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
C01 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of base of tongue. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic tongue base (dorsal surface) or Neoplasm, neoplastic tongue fixed part NEC or Neoplasm, neoplastic tongue posterior (third) or Neoplasm, neoplastic tongue root or Neoplasm, neoplastic tongue surface (dorsal) base .
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

- Carcinoma of larynx
- Carcinoma of supraglottis
- Carcinoma of tongue base - dorsal surface
- Malignant neoplasm of base of tongue dorsal surface
- Malignant tumor of base of tongue
- Primary malignant neoplasm of base of tongue
- Primary malignant neoplasm of dorsal surface of tongue
- Primary squamous cell carcinoma of base of tongue
- Primary squamous cell carcinoma of supraglottis

Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Malignant neoplasm of dorsal surface of base of tongue
- Malignant neoplasm of fixed part of tongue NOS
- Malignant neoplasm of posterior third of tongue
Use Additional Code
Use Additional CodeThe “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.

Table of Neoplasms
This code is referenced 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.

Patient Education
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.
