Inclusion terms
Alternative wording in documentation that is classified to M23.2.
- Old bucket-handle tear
Excludes1 — never code together — inherited from M23
The conditions below can never be reported together with M23.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
