M92.599 vs M96
M92.599 (Other juvenile osteochondrosis of tibia and fibula, unspecified leg) compared with M96 (Intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. M92.599 carries an Excludes1 note covering M96: “postprocedural chondropathies (M96.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
