What does ICD code C02.0 G mean?

C02.0: Malignant neoplasm: Dorsal surface of tongue

You have tongue cancer.

The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.

The tongue is mostly made up of muscles. The tongue is important for chewing, swallowing and speaking. It is connected to the back of the throat. There are many taste buds on the surface of the tongue. The taste buds have lots of small nerves, allowing us to perceive taste.

You have tongue cancer affecting the front of the tongue.

Please note: This ICD code may also derive from the ICD-O system. If this is the case, there are usually additional letters and numbers in addition to the code. It starts with the letter M, followed by 4 digits and then a slash. There is another digit after the slash.

If it is an ICD-O code, then this does not describe a malignant cancer in all cases. The last digit after the slash gives you more detailed information about this:

/0 – The tumor is benign. Cells in a tissue multiply uncontrollably. However, they are not destroying the surrounding tissue and are also not spreading throughout the body.
/1 – It is not known for sure whether the tumor is benign or malignant.
/2 – It is an early form of cancer, a precancerous stage where the cells are altered and multiply uncontrollably. However, they are not yet spreading beyond a certain margin and cannot spread to other organs either.
/3 – It is a malignant cancer. The cells in the affected tissue are altered and multiply uncontrollably. They can destroy the surrounding tissue and spread throughout the body.
/6 – It is a metastasis. Cancer cells have spread from the originally affected site to a different site in the body and have further multiplied there.
/9 – It is either a malignant cancer or a metastasis. The cells in the affected tissue are altered and multiply uncontrollably. However, it is impossible to say whether these cells derive originally from the affected site or have spread there from a different site in the body.

Additional indicator

On medical documents, the ICD code is often appended by letters that indicate the diagnostic certainty or the affected side of the body.

G: Confirmed diagnosis
V: Tentative diagnosis
Z: Condition after
A: Excluded diagnosis
L: Left
R: Right
B: Both sides

Note

This information is not intended for self-diagnosis and does not replace professional medical advice from a doctor. If you find an ICD code on a personal medical document, please also note the additional indicator used for diagnostic confidence.
Your doctor will assist you with any health-related questions and explain the ICD diagnosis code to you in a direct consultation if necessary.
