What This Code Means
M85.332 is the ICD-10-CM diagnosis code for osteitis condensans, left forearm. A bone condition where the left forearm develops increased bone density and hardening, typically affecting the radius or ulna bones. M85.332 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering disorders of bone density and structure (m80-m85).
M85.332 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.
Ensure documentation clearly indicates left forearm involvement before assigning this laterality-specific code.
