2022 ICD-10-CM Code D00.00

Carcinoma in situ of oral cavity, unspecified site

Version 2021

Valid for Submission

ICD-10:D00.00
Short Description:Carcinoma in situ of oral cavity, unspecified site
Long Description:Carcinoma in situ of oral cavity, unspecified site

Code Classification

  • Neoplasms (C00–D48)
    • In situ neoplasms (D00-D09)
      • Carcinoma in situ of oral cavity, esophagus and stomach (D00)

D00.00 is a billable diagnosis code used to specify a medical diagnosis of carcinoma in situ of oral cavity, unspecified site. The code D00.00 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 D00.00 might also be used to specify conditions or terms like carcinoma in situ of floor of mouth, carcinoma in situ of major salivary gland, carcinoma in situ of minor salivary gland, carcinoma in situ of mouth, carcinoma in situ of oral cavity , carcinoma in situ of oral cavity, lips, salivary glands, etc.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: book-leaf (mouth) ; buccal (cavity) ; cavity ; cavity buccal ; cavity oral ; junction hard and soft palate ; mouth ; etc

Unspecified diagnosis codes like D00.00 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

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Convert D00.00 to ICD-9 Code

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D00.00 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The code D00.00 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

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.
