M93.013 ICD-10-CM Code: Acute slipped upper femoral epiphysis, stable (nontraumatic), unspecified hip

M93.013 is the ICD-10-CM diagnosis code for acute slipped upper femoral epiphysis, stable (nontraumatic), unspecified hip. A sudden slipping of the growth plate at the top of the thighbone in an adolescent, where the bone head remains stable in its socket; affects one hip but the specific side is not documented. M93.013 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).

M93.013 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 acute onset is documented without specification of right or left hip; consider querying provider for laterality if available in medical record.
