Patient presents with classic symptoms suggestive of Zenker's diverticulum, including dysphagia, regurgitation of undigested food, halitosis, and a sensation of a lump in the throat.  The patient reports occasional coughing and choking episodes, particularly after meals.  Symptoms have been progressively worsening over the past six months.  The patient denies significant weight loss, heartburn, or odynophagia.  Physical examination reveals no palpable neck masses.  A barium esophagram was ordered and confirmed the diagnosis of Zenker's diverticulum, demonstrating a posterior hypopharyngeal pouch consistent with this diagnosis.  Differential diagnosis included esophageal stricture, achalasia, and esophageal cancer.  Given the confirmed diagnosis of Zenker's diverticulum, treatment options including surgical intervention such as cricopharyngeal myotomy and diverticulectomy, and endoscopic procedures were discussed with the patient. The risks and benefits of each approach were explained, and the patient will be scheduled for a consultation with a thoracic surgeon to determine the most appropriate course of action.  ICD-10 code K22.5, Zenker's diverticulum, has been assigned.  CPT codes for the consultation and subsequent procedures will be determined and documented accordingly.  Follow-up appointment scheduled in two weeks to discuss the surgical plan and address any patient concerns.
