C44.30Unspecified malignant neoplasm of skin of other and unspecified parts of face

C44.30 is the ICD-10-CM diagnosis code for unspecified malignant neoplasm of skin of other and unspecified parts of face. It belongs to category C44 (other and unspecified malignant neoplasm 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 C44.3, choose C44.30 (Unspecified malignant neoplasm of skin of other and unspecified parts of face) only when documentation doesn't support a more specific option: basal cell carcinoma of skin of other and unspecified parts of face (C44.31), squamous cell carcinoma of skin of other and unspecified parts of face (C44.32) and other specified malignant neoplasm of skin of other and unspecified parts of face (C44.39).

To report this condition, pick the subcode that matches the documentation: C44.300 (face), C44.301 (nose) and C44.309 (face).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
