Patient presents with clinical features suggestive of small vessel ischemic disease (SVID). Symptoms include (but are not limited to) gait disturbances, such as slow gait speed and magnetic gait, cognitive decline including executive dysfunction and memory impairment, and urinary incontinence. Neuroimaging, specifically brain MRI with or without contrast, reveals white matter hyperintensities (WMH) consistent with chronic microvascular ischemia. Lacunar infarcts may be present. Differential diagnosis includes Alzheimer's disease, normal pressure hydrocephalus, Parkinson's disease, and multiple sclerosis. Assessment considers vascular risk factors such as hypertension, diabetes mellitus, hyperlipidemia, smoking history, and atrial fibrillation. Cognitive testing, such as the Montreal Cognitive Assessment (MoCA) or Mini-Mental State Examination (MMSE), may demonstrate deficits in executive function, processing speed, and attention. Treatment plan focuses on managing vascular risk factors through lifestyle modifications (diet, exercise, smoking cessation) and pharmacotherapy (antihypertensives, statins, antiplatelet agents). Patient education regarding the importance of medication adherence and regular follow-up for monitoring disease progression and treatment efficacy is crucial. ICD-10 code I67.89 (other cerebrovascular disease) or I67.4 (cerebral amyloid angiopathy, if suspected) may be appropriate depending on clinical presentation and diagnostic certainty. CPT codes for evaluation and management (E/M) services, neuropsychological testing, and diagnostic imaging should be used as appropriate.
