Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Old bucket-handle tear
Other codes that can never be billed with M23.2
These codes carry an Excludes1 note pointing at M23.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M23.2 alone.
- S83.2Tear of meniscus, current injury
Risk adjustment
M23.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
