Valid for Submission
C43.20 is a billable diagnosis code used to specify a medical diagnosis of malignant melanoma of unspecified ear and external auricular canal. The code C43.20 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 C43.20 might also be used to specify conditions or terms like malignant melanoma of auricle , malignant melanoma of ear and/or external auditory canal, malignant melanoma of external auditory meatus, malignant melanoma of skin of ear, malignant melanoma of skin of external auditory canal , malignant neoplasm of skin of external auditory meatus, etc.
Unspecified diagnosis codes like C43.20 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.
The code C43.20 is linked to some Quality Measures as part of Medicare's Quality Payment Program (QPP). When this code is used as part of a patient's medical record the following Quality Measures might apply: Melanoma Reporting.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Malignant melanoma of auricle
- Malignant melanoma of ear and/or external auditory canal
- Malignant melanoma of external auditory meatus
- Malignant melanoma of skin of ear
- Malignant melanoma of skin of external auditory canal
- Malignant neoplasm of skin of external auditory meatus
Diagnostic Related Groups - MS-DRG Mapping
|MS-DRG||MS-DRG Title||MCD||Relative Weight|
|595||MAJOR SKIN DISORDERS WITH MCC||09||2.0121|
|596||MAJOR SKIN DISORDERS WITHOUT MCC||09||0.9892|
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
Convert C43.20 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code C43.20 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.
Quality Payment Program Measures
When code C43.20 is part of the patient's diagnoses the following Quality Measures apply and affect reimbursement. The objective of Medicare's Quality Measures is to improve patient care by making it more: effective, safe, efficient, patient-centered and equitable.

Information for Patients
Melanoma is the most serious type of skin cancer. Often the first sign of melanoma is a change in the size, shape, color, or feel of a mole. Most melanomas have a black or black-blue area. Melanoma may also appear as a new mole. It may be black, abnormal, or "ugly looking."
Thinking of "ABCDE" can help you remember what to watch for:
- Asymmetry - the shape of one half does not match the other
- Border - the edges are ragged, blurred or irregular
- Color - the color is uneven and may include shades of black, brown and tan
- Diameter - there is a change in size, usually an increase
- Evolving - the mole has changed over the past few weeks or months
Surgery is the first treatment of all stages of melanoma. Other treatments include chemotherapy and radiation, biologic, and targeted therapies. Biologic therapy boosts your body's own ability to fight cancer. Targeted therapy uses substances that attack cancer cells without harming normal cells.
