Patient presents with inability to ambulate, demonstrating impaired mobility and gait disturbance.  Assessment reveals difficulty walking, limited ambulation distance, and dependence on assistive devices such as a walker or wheelchair.  Possible etiologies include muscle weakness, joint pain, neurological deficits, balance problems, and cardiovascular compromise.  The patient's medical history includes [relevant past medical history, e.g., osteoarthritis, stroke, congestive heart failure].  Physical examination findings include [objective findings related to ambulation, e.g., decreased range of motion, muscle atrophy, abnormal gait patterns, antalgic gait].  Diagnostic considerations include [differential diagnosis, e.g., osteoarthritis, peripheral neuropathy, Parkinson's disease, cerebrovascular accident].  Plan includes further evaluation to determine the underlying cause of ambulation difficulty, referral to physical therapy for gait training and strengthening exercises, occupational therapy assessment for adaptive equipment needs, and medication management for pain or underlying medical conditions.  Patient education focuses on fall prevention strategies, home safety modifications, and the importance of adherence to the prescribed treatment plan.  The patient's progress and response to interventions will be closely monitored.  Coding considerations include ICD-10 codes for the specific underlying condition causing the inability to ambulate, such as [relevant ICD-10 codes, e.g., I73.9 for peripheral vascular disease, M17.12 for unilateral primary osteoarthritis knee, G81.0 for hemiplegia affecting right dominant side].  Medical billing will reflect the services provided, including evaluation and management codes, physical therapy, occupational therapy, and any diagnostic testing or procedures performed.  The focus of care is to improve mobility, enhance functional independence, and optimize the patient's quality of life.
