M61 Calcification and ossification of muscle

ICD-10-CM category M61 sits in Chapter 13 (Diseases of the musculoskeletal system and connective tissue, M00-M99). It contains 154 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.
