Valid for Submission
C44.221 is a billable diagnosis code used to specify a medical diagnosis of squamous cell carcinoma of skin of unspecified ear and external auricular canal. The code C44.221 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 C44.221 might also be used to specify conditions or terms like carcinoma in situ of ear, carcinoma in situ of skin of ear, intraepidermal squamous carcinoma of ear, malignant neoplasm of skin of external auditory meatus, primary squamous cell carcinoma of ear , squamous cell carcinoma of auricle of ear, etc.
Unspecified diagnosis codes like C44.221 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.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Carcinoma in situ of ear
- Carcinoma in situ of skin of ear
- Intraepidermal squamous carcinoma of ear
- Malignant neoplasm of skin of external auditory meatus
- Primary squamous cell carcinoma of ear
- Squamous cell carcinoma of auricle of ear
- Squamous cell carcinoma of external auditory canal
- Squamous cell carcinoma of skin of ear

Information for Patients
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.
