Mrs. T is schizophrenic. She has refused for two years to leave her home or open the windows since people might "see" her. Mrs. T also has diabetes, hypertension and heart failure. Her hypertension is not under control. Your agency is seeing Mrs. T to evaluate her current medication regimen and determine if a medication adjustment is appropriate. Mrs. T ambulates independently and safely within her home across multiple surfaces. She refuses to go outside the home to demonstrate her ability to go up and down the porch steps. How should you answer M1860 (Ambulation/locomotion) based on the scenario above?
