ICD-10 Code C43.39 – Malignant melanoma of other parts of face (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C43.39 – Malignant melanoma of other parts of face
What it is
C43.39 identifies a malignant melanoma located on other specified parts of the face. Use it when the record documents melanoma of facial skin outside the more specific face sites listed elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Melanoma is typically described as a suspicious pigmented or changing skin lesion, often with asymmetry, irregular borders, color variation, or growth.
When to use this code
Use C43.39 when the provider documents malignant melanoma on a facial area that is not separately indexed to another more specific facial site. It also fits pathology-confirmed melanoma of the face when the anatomic location is recorded as “other parts of face.”
Check documentation if the note only says “face” without further detail, or if another facial subsite is named. Accurate site selection matters for coding specificity.
Do not use for
Do not use this code for benign skin lesions, melanoma in situ, or melanoma on nonfacial sites. If the chart does not clearly support a malignant diagnosis or facial location, check documentation.
Coding tip
Match the exact anatomic wording in the pathology or operative note before assigning C43.39.
