Examination notes or functional assessments should describe your inability to rise from a squatting position, climb stairs, rise from a deep chair without assistance, or raise your arms.
For the 60% rating, the same kinds of functional findings about proximal muscle wasting matter — exam notes, physical therapy records, or a VA examination that documents the specific movements you cannot perform.
For the 30% rating, clinical records should show a provider's observations of striae, obesity, and moon face, along with lab results reflecting glucose intolerance and notes on vascular fragility such as easy bruising.
