C44 Other and unspecified malignant neoplasm of skin
ICD-10-CM category C44 sits in Chapter 2 (Neoplasms, C00-D49). It contains 101 billable codes for FY2027, effective October 1, 2026 to September 30, 2027. Always code to the most specific code available: a code with more characters that describes the diagnosis more precisely takes priority over a shorter one.
