About 4A0FXEJ
4A0FXEJ is the ICD-10-PCS code for a measurement procedure on the musculoskeletal using an external approach with body composition (qualifier: air displacement plethysmography). In ICD-10-PCS, measurement means determining the level of a physiological or physical function at a point in time.
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2027, effective October 1, 2026.
