About M94.2
M94.2 is the ICD-10-CM diagnosis code for Chondromalacia. It belongs to category M94 (other disorders of cartilage), block M91-M94 (Chondropathies) 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 M94 (other disorders of cartilage), M94.2 is specifically for Chondromalacia. Related codes cover Chondrocostal junction syndrome [Tietze] (M94.0), relapsing polychondritis (M94.1), Chondrolysis (M94.3), other specified disorders of cartilage (M94.8) and disorder of cartilage, unspecified (M94.9).
To report this condition, pick the subcode that matches the documentation: M94.20 (unspecified site), M94.21 (shoulder), M94.22 (elbow), M94.23 (wrist), M94.24 (joints of hand), M94.25 (hip), M94.26 (knee), M94.27 (ankle and joints of foot) and 2 more.
Don't report M94.2 together with the conditions in its Excludes1 note: chondromalacia patellae (M22.4).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
