About C43.3
C43.3 is the ICD-10-CM diagnosis code for malignant melanoma of other and unspecified parts of face. It belongs to category C43 (malignant melanoma of skin), block C43-C44 (melanoma and other malignant neoplasms of skin) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within C43, choose C43.3 (other and unspecified parts of face) only when documentation doesn't support a more specific option: lip (C43.0), eyelid, including canthus (C43.1), ear and external auricular canal (C43.2), scalp and neck (C43.4), trunk (C43.5), upper limb, including shoulder (C43.6), lower limb, including hip (C43.7), overlapping sites of skin (C43.8) and 1 more.
To report this condition, pick the subcode that matches the documentation: C43.30 (face), C43.31 (nose) and C43.39 (face).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
