Code Classification

  • Neoplasms
    (C00–D49)
    • In situ neoplasms
      (D00-D09)
      • Carcinoma in situ of oral cavity, esophagus and stomach
        (D00)

D00.0 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of carcinoma in situ of lip, oral cavity and pharynx. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Carcinoma in situ of lip, oral cavity and pharynx

Non-specific codes like D00.0 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for carcinoma in situ of lip, oral cavity and pharynx:

  • Use D00.00 for Carcinoma in situ of oral cavity, unspecified site - BILLABLE CODE

  • Use D00.01 for Carcinoma in situ of labial mucosa and vermilion border - BILLABLE CODE

  • Use D00.02 for Carcinoma in situ of buccal mucosa - BILLABLE CODE

  • Use D00.03 for Carcinoma in situ of gingiva and edentulous alveolar ridge - BILLABLE CODE

  • Use D00.04 for Carcinoma in situ of soft palate - BILLABLE CODE

  • Use D00.05 for Carcinoma in situ of hard palate - BILLABLE CODE

  • Use D00.06 for Carcinoma in situ of floor of mouth - BILLABLE CODE

  • Use D00.07 for Carcinoma in situ of tongue - BILLABLE CODE

  • Use D00.08 for Carcinoma in situ of pharynx - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Use Additional Code

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:
  • 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 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • carcinoma in situ of aryepiglottic fold or interarytenoid fold, laryngeal aspect D02.0
  • carcinoma in situ of epiglottis NOS D02.0
  • carcinoma in situ of epiglottis suprahyoid portion D02.0
  • carcinoma in situ of skin of lip D03.0 D04.0

Oral Cancer

What is oral cancer?

Oral cancer is cancer of the mouth. It is a type of head and neck cancer. Most oral cancers are squamous cell cancers. They begin in the flat cells that cover the surfaces of your mouth, tongue, and lips. The cancer cells may spread into deeper tissue as the cancer grows.

Most oral cancers are related to tobacco use, heavy alcohol use, or an HPV infection.

Who is more likely to develop oral cancer?

Anyone can get oral cancer, but you are more likely to develop it if you:

  • Use tobacco or drink lots of alcohol. Your risk of developing oral cancer is even higher if you do both.
  • Are male.
  • Are over ago 40.
  • Have HPV.
  • Have a history of head or neck cancer.
  • Get frequent sun exposure (for lip cancer).

What are the symptoms of oral cancer?

The symptoms of oral cancer may include:

  • A white or red patch in your mouth
  • A lip or mouth sore that won't heal
  • Bleeding, pain, or numbness in the lip or mouth
  • Loose teeth or dentures that no longer fit well
  • Problems or pain with swallowing
  • A lump in your neck
  • Ear pain
  • Trouble moving your mouth or jaw
  • Swelling of the jaw
  • A sore throat or feeling that something is caught in the throat

If you have any of these symptoms for more than two weeks, see your health care provider or dentist. Oral cancer can spread quickly, so it's important to find it early.

How is oral cancer diagnosed?

To find out if you have oral cancer, your provider may use:

  • A physical exam of the lips and mouth.
  • An endoscopy.
  • A biopsy or other procedure to collect cells from the lip or oral cavity. The cells are viewed under a microscope to find out if they are abnormal.
  • Imaging tests.

What are the treatments for oral cancer?

The treatments for oral cancer include surgery, radiation therapy, or both. After surgery, some people also need chemotherapy to kill any cancer cells that are left.

Can oral cancer be prevented?

There are steps you can take to help prevent oral cancer:

  • Not smoking
  • Limiting alcohol use or not drinking at all
  • Getting regular dental exams

Throat Cancer

Throat cancer is a type of head and neck cancer. Throat cancer has different names, depending on which part of the throat is affected. The different parts of your throat are called the oropharynx, the hypopharynx, the nasopharynx, and the larynx, or voice box.

The main risk factors for throat cancer are using tobacco heavy drinking. Certain types of throat cancer also have other risk factors. For example, having HPV is a risk factor for oropharyngeal cancer.

Symptoms of throat cancer may include:

  • A sore throat that does not go away
  • A lump in the neck
  • Pain or ringing in the ears
  • Trouble swallowing
  • Ear pain

To diagnose throat cancers, doctors may do a physical exam and history, imaging tests, and a biopsy. You may also need other tests, depending on the type of cancer. Treatments include surgery, radiation therapy, and chemotherapy. Treatment for some types of throat cancer may also include targeted therapy. Targeted therapy uses drugs or other substances that attack specific cancer cells with less harm to normal cells.
