Patient presents with symptoms suggestive of pneumothorax, commonly known as a collapsed lung.  Onset of symptoms, including acute chest pain, dyspnea, and shortness of breath, occurred [timeframe].  The patient reports [character of pain; e.g., sharp, stabbing, aching] pain localized to [location of pain; e.g., right side, left side, upper chest, lower chest].  Associated symptoms may include tachypnea, decreased breath sounds on auscultation, and cyanosis.  The patient's medical history includes [relevant medical history; e.g., smoking, recent trauma, history of lung disease such as COPD or asthma, previous pneumothorax].  Physical examination reveals [physical findings; e.g., reduced or absent breath sounds on the affected side, hyperresonance to percussion, tracheal deviation].  Differential diagnosis includes pleural effusion, pneumonia, and pulmonary embolism.  Initial diagnostic imaging with chest x-ray, and potentially CT scan if necessary, is ordered to confirm the presence and extent of the pneumothorax.  Diagnosis of pneumothorax is confirmed based on the presence of air in the pleural space observed on imaging.  Treatment plan includes observation for small, stable pneumothoraces versus intervention for larger or symptomatic pneumothoraces.  Interventions may include needle aspiration, chest tube placement, or pleurodesis.  Patient education on pneumothorax symptoms, causes, treatment, and potential complications provided.  Follow-up care scheduled for reassessment and monitoring of resolution.  ICD-10 code J93.8 (Spontaneous tension pneumothorax), or other applicable ICD-10 code based on etiology, assigned.  CPT codes for procedures performed, such as chest tube insertion (32551), needle aspiration (32554), or pleurodesis (32560), will be documented accordingly.
