Patient presents with inability to ambulate, documented as ambulation impairment, gait disturbance, and mobility limitation.  Assessment reveals functional mobility deficits impacting independent ambulation.  Contributing factors may include muscle weakness, lower extremity weakness, balance problems, impaired coordination, joint pain, or neurological deficits.  Patient reports difficulty walking, impaired gait, and limited mobility.  On examination, patient demonstrates unsteady gait, reduced stride length, and reliance on assistive devices such as a walker or wheelchair.  The inability to ambulate impacts activities of daily living (ADLs) and increases fall risk.  Plan includes physical therapy for gait training, balance exercises, and strengthening exercises to improve mobility and ambulation status.  Occupational therapy referral to address adaptive equipment needs and strategies for improving functional independence.  Fall risk assessment completed and fall precautions implemented.  Patient education provided on home safety and assistive device use.  Diagnosis:  Unable to Ambulate.  ICD-10 code R26.2 (Difficulty in walking, not elsewhere classified) may be considered, with further specificity based on underlying etiology.  Continued monitoring and reassessment of ambulation status are planned.
