M1A Chronic gout
ICD-10-CM category M1A sits in Chapter 13 (Diseases of the musculoskeletal system and connective tissue, M00-M99). It contains 242 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.
