Limited bending and straightening of the forearm at the elbow joint.
To support a rating under this code, medical evidence needs to show that your forearm flexion is limited to 100 degrees and your extension is limited to 45 degrees. Range-of-motion measurements recorded during a VA or private medical examination are central to this. A VA Compensation and Pension exam will typically use a goniometer to measure these angles, and those recorded degrees are what VA compares to the code's criteria. Repeated measurements matter because painful motion or fatigue can affect results. Medical records documenting your elbow or forearm condition over time help establish consistency. Statements from you or people who know you describing how restricted forearm movement affects tasks at work or at home — such as lifting, carrying, or reaching — can help VA understand the full impact of the limitation, though the measured degrees of motion are the deciding factor for the rating level itself.
