M23.2 vs S83.2
M23.2 (Derangement of meniscus due to old tear or injury) compared with S83.2 (Tear of meniscus, current injury), 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. S83.2 carries an Excludes1 note covering M23.2: “old bucket-handle tear (M23.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
Yes, when both are documented. S83.2 carries an Excludes2 note covering M23.2: “internal derangement of knee (M23.-)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
