Valid for Submission
D00.06 is a billable diagnosis code used to specify a medical diagnosis of carcinoma in situ of floor of mouth. The code D00.06 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 D00.06 might also be used to specify conditions or terms like carcinoma in situ anterior floor of mouth, carcinoma in situ lateral floor of mouth, carcinoma in situ of floor of mouth, tumor of anterior floor of mouth or tumor of lateral floor of mouth.
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: mouth floor or mouth floor anterior portion or mouth floor lateral portion or sublingual .
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Carcinoma in situ anterior floor of mouth
- Carcinoma in situ lateral floor of mouth
- Carcinoma in situ of floor of mouth
- Tumor of anterior floor of mouth
- Tumor of lateral floor of mouth
Convert D00.06 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D00.06 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 D00.06 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 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.
