Patient presents with chief complaint of bad breath, medically termed halitosis.  The patient describes the odor as persistent and unpleasant, impacting their social interactions and self-confidence.  Onset is reported as gradual over the past six months.  Review of systems reveals no significant findings other than occasional dry mouth (xerostomia).  Medical history includes well-controlled hypertension and no known allergies.  Social history indicates daily coffee consumption and occasional alcohol use.  Dental history includes regular checkups, with the last visit six months prior.  Intraoral examination reveals no visible signs of decay or gum disease; however, a coated tongue is noted.  Diagnosis of halitosis is made based on patient-reported symptoms and clinical findings.  Differential diagnosis considered oral malodor, fetor oris, and transient bad breath.  Treatment plan includes recommendations for improved oral hygiene practices, including tongue scraping, increased water intake, and sugar-free gum to stimulate saliva production.  Patient education provided regarding the link between oral hygiene, diet, and halitosis.  Follow-up appointment scheduled in two weeks to assess the effectiveness of the recommended interventions.  ICD-10 code K11.3 (halitosis) is assigned.  CPT codes for evaluation and management services will be determined based on time spent and complexity of the encounter.
