What This Code Means
M76.30 is the ICD-10-CM diagnosis code for iliotibial band syndrome, unspecified leg. Inflammation of the iliotibial band (a thick tissue that runs along the outside of the thigh) when the specific leg is not documented. M76.30 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering other soft tissue disorders (m70-m79).
M76.30 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 only when laterality is not specified; specify right or left when documented.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for M76.30 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
