What This Code Means
M93.021 is the ICD-10-CM diagnosis code for chronic slipped upper femoral epiphysis, stable (nontraumatic), right hip. A long-standing slipping of the growth plate at the top of the right thighbone in an adolescent, where the bone head remains stable in its socket. M93.021 sits in the ICD-10-CM chapter for diseases of the musculoskeletal system and connective tissue (m00-m99), within the section covering chondropathies (m91-m94).
M93.021 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.
Chronic SUFE is typically diagnosed when symptoms have been present for weeks to months; verify timeline in clinical documentation.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for M93.021 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Chronic SUFE is typically diagnosed when symptoms have been present for weeks to months; verify timeline in clinical documentation
