Patient presents with complaints of memory problems, consistent with a diagnosis of Memory Impairment Unspecified (DSM-5 code R41.89).  The patient reports subjective cognitive decline, specifically difficulties with recent memory, but denies significant impact on daily functioning at this time.  Onset is unclear, but the patient and family members note that these concerns have been gradually increasing over the past several months.  Formal cognitive testing was not conducted during this visit, but is recommended for future evaluation to quantify the extent of the memory impairment and assist in differential diagnosis.  The patient denies any history of head trauma, stroke, or other neurological conditions.  Medical history includes hypertension and hyperlipidemia, both well-controlled with medication.  Current medications include lisinopril and atorvastatin.  Review of systems is otherwise unremarkable.  Differential diagnoses considered include age-related cognitive decline, mild cognitive impairment, and early-stage dementia.  Further evaluation is required to determine the etiology of the memory impairment and rule out other potential causes.  The patient was educated on memory strategies and provided resources for cognitive rehabilitation.  Follow-up appointment scheduled in three months for repeat cognitive assessment and further discussion regarding potential treatment options, including referral to neuropsychology if clinically indicated.  Medical billing codes may include codes for cognitive assessment and evaluation of memory complaints.  This documentation supports the medical necessity for continued evaluation and management of the patient's memory concerns.
