Patient presents with complaints consistent with gastroesophageal reflux disease (GERD) and symptoms suggestive of a hiatal hernia.  The patient reports experiencing heartburn, acid reflux, regurgitation, chest pain, and dysphagia.  Symptoms are exacerbated by bending over, lying down, and after meals.  The patient denies hematemesis or melena.  Physical examination reveals epigastric tenderness upon palpation.  A barium swallow study was ordered and confirmed the presence of a sliding hiatal hernia.  Esophagogastroduodenoscopy (EGD) was performed to evaluate the extent of esophageal damage and rule out Barrett's esophagus.  Findings from the EGD revealed mild esophagitis.  The patient's current medications include over-the-counter antacids, which provide minimal relief.  Diagnosis of hiatal hernia with GERD is confirmed based on patient symptoms, physical exam findings, and diagnostic imaging results.  The patient was counseled on lifestyle modifications, including dietary changes, weight management, and elevation of the head of the bed.  A proton pump inhibitor (PPI) was prescribed for symptom management and to promote healing of the esophagitis.  Patient education regarding the importance of medication adherence and follow-up care was provided.  Follow-up appointment scheduled in four weeks to assess treatment response and discuss further management options if necessary.  ICD-10 codes K44.9 for hiatal hernia without obstruction or gangrene and K21.9 for gastro-esophageal reflux disease without esophagitis are considered.  CPT codes for the barium swallow and EGD will be documented separately based on the specific procedures performed.
