ICD-10-CM Code C03.1

Malignant neoplasm of lower gum

Version 2020 Billable Code Neoplasm Malignant Primary

Valid for Submission

C03.1 is a billable code used to specify a medical diagnosis of malignant neoplasm of lower gum. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C03.1 might also be used to specify conditions or terms like carcinoma of lower gum or malignant tumor of lower gingiva or neoplasm of lower gum or primary malignant neoplasm of gum or primary malignant neoplasm of lower gum.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: alveolar mucosa lower ; alveolar ridge or process carcinoma lower ; alveolar ridge or process mucosa lower ; alveolus lower ; gingiva (alveolar) (marginal) lower ; gingiva (alveolar) (marginal) mandibular ; gum lower ; etc

Table of Neoplasms

The code C03.1 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.
