About M92.51

M92.51 is the ICD-10-CM diagnosis code for juvenile osteochondrosis of proximal tibia. It belongs to category M92 (other juvenile osteochondrosis), 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 4 subcodes must be used instead.

Within M92.5 (juvenile osteochondrosis of tibia and fibula), M92.51 is specifically for juvenile osteochondrosis of proximal tibia. Related codes cover unspecified juvenile osteochondrosis of tibia and fibula (M92.50), juvenile osteochondrosis of tibia tubercle (M92.52) and other juvenile osteochondrosis of tibia and fibula (M92.59).

To report this condition, pick the subcode that matches the documentation: M92.511 (right leg), M92.512 (left leg), M92.513 (bilateral) and M92.519 (unspecified leg).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2021 (title revised).

Before ICD-10, this condition was coded in ICD-9-CM as 732.4 (juvenile osteochondrosis of lower extremity, excluding foot).
