ICD-10 Code C44.20

Unspecified malignant neoplasm of skin of ear and external auricular canal

Version 2019 Non-Billable Code Neoplasm Malignant Primary
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

Not Valid for Submission

ICD-10 C44.20 is a "header" nonspecific and non-billable 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 valid for the year 2019 for the submission of HIPAA-covered transactions.

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

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

Code Classification

  • Neoplasms (C00–D48)
    • Melanoma and other malignant neoplasms of skin (C43-C44)
      • Other and unspecified malignant neoplasm of skin (C44)

Table of Neoplasms

The code C44.20 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.

The Tabular must be reviewed for the complete diagnosis code.

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.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
