ICD-10-CM Code D04.2

Carcinoma in situ of skin of ear and external auricular canal

Version 2020 Non-Billable Code Neoplasm CaInSitu

Not Valid for Submission

D04.2 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of carcinoma in situ of skin of ear and external auricular canal. The code is NOT valid for the year 2020 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: auditory ; auditory canal (external) (skin) ; auricle, ear [See Also: Neoplasm, skin, ear] ; auricular canal (external) [See Also: Neoplasm, skin, ear] ; canal auditory (external) [See Also: Neoplasm, skin, ear] ; canal auricular (external) [See Also: Neoplasm, skin, ear] ; concha [See Also: Neoplasm, skin, ear] ; etc

ICD-10:D04.2
Short Description:Ca in situ skin of ear and external auricular canal
Long Description:Carcinoma in situ of skin of ear and external auricular canal

Consider the following ICD-10 codes with a higher level of specificity:

  • D04.20 - Carcinoma in situ of skin of unspecified ear and external auricular canal
  • D04.21 - Carcinoma in situ of skin of right ear and external auricular canal
  • D04.22 - Carcinoma in situ of skin of left ear and external auricular canal

Table of Neoplasms

The code D04.2 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


Skin Cancer

Skin cancer is the most common form of cancer in the United States. The two most common types are basal cell cancer and squamous cell cancer. They usually form on the head, face, neck, hands, and arms. Another type of skin cancer, melanoma, is more dangerous but less common.

Anyone can get skin cancer, but it is more common in people who

  • Spend a lot of time in the sun or have been sunburned
  • Have light-colored skin, hair and eyes
  • Have a family member with skin cancer
  • Are over age 50

You should have your doctor check any suspicious skin markings and any changes in the way your skin looks. Treatment is more likely to work well when cancer is found early. If not treated, some types of skin cancer cells can spread to other tissues and organs. Treatments include surgery, radiation therapy, chemotherapy, photodynamic therapy (PDT), and biologic therapy. PDT uses a drug and a type of laser light to kill cancer cells. Biologic therapy boosts your body's own ability to fight cancer.
