Patient presents with symptoms consistent with lobar pneumonia.  Chief complaints include productive cough with rusty or blood-tinged sputum, fever, chills, pleuritic chest pain, dyspnea, and fatigue.  Physical examination reveals diminished breath sounds, crackles, and dullness to percussion over the affected lobe.  Symptoms onset began approximately three days ago.  Patient reports recent upper respiratory infection.  Vital signs demonstrate elevated temperature (102.5 F), tachycardia, and tachypnea.  Chest X-ray confirms consolidation in the right lower lobe, consistent with lobar pneumonia diagnosis.  Differential diagnosis considered bacterial pneumonia, viral pneumonia, and bronchitis.  Based on clinical presentation and imaging findings, the diagnosis of lobar pneumonia is confirmed.  Treatment plan includes antibiotic therapy with ceftriaxone intravenously,  oxygen supplementation as needed,  analgesics for pain management, and antipyretics for fever reduction.  Patient education provided on the importance of medication adherence, hydration, rest, and follow-up care.  Patient advised to return for re-evaluation in one week to assess treatment response and resolution of symptoms.  Medical coding includes ICD-10 code J18.1 for lobar pneumonia, unspecified organism.  CPT codes will be assigned based on specific procedures performed, including chest X-ray and intravenous administration of medication.  Prognosis is generally favorable with appropriate antibiotic treatment and supportive care.  Patient monitoring will include respiratory status, oxygen saturation, temperature, and response to antibiotics.  Potential complications such as pleural effusion, empyema, and sepsis will be monitored closely.
