L98 Oth disorders of skin, subcu, not elsewhere classified
ICD-10-CM category L98 sits in Chapter 12 (Diseases of the skin and subcutaneous tissue, L00-L99). It contains 145 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.
