Patient presents with complaints consistent with a sleep disorder.  Presenting symptoms include (but are not limited to) insomnia, sleep apnea symptoms (e.g., snoring, witnessed apnea episodes, gasping for air during sleep), excessive daytime sleepiness, fatigue, difficulty concentrating, restless legs syndrome symptoms (e.g., creeping or crawling sensations in the legs, urge to move legs), parasomnias (e.g., sleepwalking, night terrors), circadian rhythm sleep-wake disorders (e.g., shift work sleep disorder, jet lag), or other sleep disturbances.  Onset, duration, frequency, and severity of symptoms were documented.  Impact on daily activities, including work performance, social interactions, and overall quality of life, was assessed.  Past medical history, family history of sleep disorders, medication history (including over-the-counter sleep aids), and substance use (including caffeine and alcohol) were reviewed.  Physical examination findings relevant to sleep disorders, such as elevated BMI, hypertension, or signs of other medical conditions that may contribute to sleep problems, were noted.  Differential diagnoses considered included obstructive sleep apnea, insomnia, restless legs syndrome, narcolepsy, circadian rhythm sleep disorders, and parasomnias.  Assessment for sleep disorder includes sleep diary, Epworth Sleepiness Scale, STOP-BANG questionnaire, and consideration for polysomnography or other sleep studies.  Initial treatment plan may include sleep hygiene education, cognitive behavioral therapy for insomnia (CBT-I), lifestyle modifications (e.g., weight management, regular exercise), and or referral to a sleep specialist for further evaluation and management.  Follow-up appointments scheduled to monitor treatment efficacy and adjust management plan as needed.  ICD-10 codes for sleep disorders (e.g., G47, F51) will be used for diagnostic coding and medical billing purposes.  Patient education materials on sleep disorders and sleep hygiene practices were provided.
