Patient presents with subjective complaints of memory problems, described as difficulty recalling recent events, names, and appointments.  These memory lapses are impacting daily activities and causing significant concern.  Objective assessment reveals deficits in short-term memory as evidenced by impaired performance on age-adjusted memory tests, including delayed recall tasks.  Differential diagnosis includes age-related cognitive decline, mild cognitive impairment (MCI), dementia (Alzheimer's disease, vascular dementia, Lewy body dementia), depression, medication side effects, and vitamin B12 deficiency.  Further evaluation will include a comprehensive cognitive assessment, laboratory studies (CBC, CMP, thyroid panel, vitamin B12 levels), and potentially neuroimaging (MRI brain) to rule out underlying medical conditions.  Current impression is consistent with memory impairment, etiology undetermined.  Patient education provided on memory strategies, lifestyle modifications (diet, exercise, sleep hygiene), and potential impact of comorbidities such as hypertension and diabetes on cognitive function.  Referral to neuropsychology for formal neurocognitive testing and consideration for memory clinic evaluation.  Follow-up scheduled in four weeks to review test results and discuss management plan, which may include pharmacotherapy options for cognitive enhancement if indicated.  ICD-10 code R41.3 (Memory impairment, not elsewhere classified) is provisionally assigned, subject to change pending further diagnostic clarification.  CPT codes for evaluation and management services will be determined based on time spent and complexity of medical decision-making.
