What This Code Means
M23.232 is the ICD-10-CM diagnosis code for derangement of other medial meniscus due to old tear or injury, left knee. Damage to other parts of the inner knee cartilage (meniscus) on the left knee from an old tear or injury causing displacement. M23.232 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering other joint disorders (m20-m25).
M23.232 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.
