Patient presents with complaints of memory loss, a common symptom of memory deficit or memory impairment.  The patient reports difficulty recalling recent events, names, and appointments, impacting daily functioning.  Assessment includes a detailed cognitive evaluation, including memory testing such as short-term memory assessment, long-term memory assessment, and working memory assessment.  Differential diagnosis includes age-related cognitive decline, mild cognitive impairment (MCI), dementia, Alzheimer's disease, and other neurological conditions.  The Mini-Mental State Examination (MMSE) score is documented.  Further investigation may include neuropsychological testing, brain imaging (MRI, CT scan), and bloodwork to rule out reversible causes of memory impairment such as vitamin deficiencies (B12), thyroid dysfunction, and medication side effects.  Current medication list reviewed and reconciled.  The patient's social history, including alcohol use, substance use, and current stressors, is explored to assess potential contributing factors.  Family history of dementia and other neurological disorders is noted.  Initial treatment plan includes memory strategies and cognitive rehabilitation techniques.  Patient education provided regarding lifestyle modifications such as regular exercise, balanced diet, and cognitive stimulation activities.  Follow-up appointment scheduled to monitor progress and adjust treatment plan as needed.  Referral to a neurologist or geriatrician may be considered for further evaluation and management.  ICD-10 code (e.g., R41.3 for Mild Cognitive Impairment, so please specify the appropriate code based on the specific type of memory deficit) and CPT code (e.g., 99214 for a level 4 office visit, replace with the correct code based on services provided) are documented for medical billing and coding purposes.  Prognosis discussed with the patient and family.
