Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Chondrocalcinosis NOS
Other codes that can never be billed with M11.2
These codes carry an Excludes1 note pointing at M11.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M11.2 alone.
- E83.5Disorders of calcium metabolism
Risk adjustment
M11.2 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.
