M88 vs M96
M88 (Osteitis deformans [Paget's disease of bone]) 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. M88 carries an Excludes1 note covering M96: “postprocedural osteopathies (M96.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
