About M61.2
M61.2 is the ICD-10-CM diagnosis code for paralytic calcification and ossification of muscle. It belongs to category M61 (calcification and ossification of muscle), block M60-M63 (disorders of muscles) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 10 subcodes must be used instead.
Within M61 (calcification and ossification of muscle), M61.2 is specifically for paralytic calcification and ossification of muscle. Related codes cover myositis ossificans traumatica (M61.0), myositis ossificans progressiva (M61.1), s associated with burns (M61.3), other calcification of muscle (M61.4), other ossification of muscle (M61.5) and unspecified (M61.9).
To report this condition, pick the subcode that matches the documentation: M61.20 (unspecified site), M61.21 (shoulder), M61.22 (upper arm), M61.23 (forearm), M61.24 (hand), M61.25 (thigh), M61.26 (lower leg), M61.27 (ankle and foot) and 2 more.
