What This Code Means
M12.19 is the ICD-10-CM diagnosis code for kaschin-beck disease, multiple sites. Kaschin-Beck disease is a chronic joint disorder caused by selenium deficiency and organic iodine exposure, resulting in joint pain, stiffness, and deformity affecting multiple joints throughout the body. M12.19 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering inflammatory polyarthropathies (m05-m14).
M12.19 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Use this code when Kaschin-Beck disease involves three or more different joint sites.
