C44.20 - Unspecified malignant neoplasm of skin of ear and external auricular canal

Version 2023
ICD-10:C44.20
Short Description:Unsp malignant neoplasm skin/ ear and external auric canal
Long Description:Unspecified malignant neoplasm of skin of ear and external auricular canal
Status: Not Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Neoplasms (C00–D48)
    • Melanoma and other malignant neoplasms of skin (C43-C44)
      • Other and unspecified malignant neoplasm of skin (C44)

C44.20 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of unspecified malignant neoplasm of skin of ear and external auricular canal. The code is not specific and is NOT valid for the year 2023 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.

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

Unspecified diagnosis codes like C44.20 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.

Specific Coding for Unsp malignant neoplasm skin/ ear and external auric canal

Non-specific codes like C44.20 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for unsp malignant neoplasm skin/ ear and external auric canal:

  • BILLABLE CODE - Use C44.201 for Unspecified malignant neoplasm of skin of unspecified ear and external auricular canal
  • BILLABLE CODE - Use C44.202 for Unspecified malignant neoplasm of skin of right ear and external auricular canal
  • BILLABLE CODE - Use C44.209 for Unspecified malignant neoplasm of skin of left ear and external auricular canal

Table of Neoplasms

This code is referenced 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.

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 :

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.
