Patient presents with subjective complaints of memory loss.  The patient reports difficulties with recent memory, including forgetting appointments, misplacing items, and repeating questions.  Onset is reported as gradual over the past [timeframe, e.g., six months].  The patient denies any specific precipitating event.  Family members corroborate the reported memory decline, noting increased forgetfulness and difficulty with recalling recent conversations.  Review of systems reveals no other significant neurological symptoms such as headaches, dizziness, or changes in vision or speech.  Mental status examination demonstrates intact orientation to person and place, but difficulty with time.  Short-term memory is impaired, as evidenced by difficulty recalling three unrelated words after a five-minute delay.  Long-term memory appears relatively preserved.  The patient's medical history includes [list relevant medical history, e.g., hypertension, hyperlipidemia].  Current medications include [list medications].  Differential diagnosis includes age-related cognitive decline, mild cognitive impairment, Alzheimer's disease, and other dementias.  Assessment for underlying medical conditions contributing to memory impairment, such as vitamin B12 deficiency, hypothyroidism, and depression, is warranted.  Initial plan includes cognitive testing, laboratory studies including complete blood count, comprehensive metabolic panel, thyroid stimulating hormone, vitamin B12 levels, and potentially neuroimaging such as MRI of the brain.  Patient and family education provided regarding memory loss, potential causes, and treatment options.  Follow-up appointment scheduled in [timeframe, e.g., four weeks] to review test results and discuss further management.  ICD-10 codes to be considered include R41.3 (Memory impairment, not elsewhere classified), G31.84 (Mild cognitive impairment, so stated), and potentially others depending on further evaluation.  Medical billing and coding will be finalized upon completion of the diagnostic workup.
