Patient presented with symptoms suggestive of coronary artery disease, including angina pectoris, chest pain, and shortness of breath.  The patient's medical history includes hypertension, hyperlipidemia, and a family history of coronary artery disease.  Physical examination revealed stable vital signs.  Electrocardiogram showed ST-segment depression consistent with myocardial ischemia.  Cardiac biomarkers, including troponin levels, were elevated.  Coronary angiography revealed significant stenosis in the left anterior descending artery.  A diagnosis of coronary artery disease was made, and percutaneous transluminal coronary angioplasty (PTCA) was indicated.  The procedure was performed successfully with placement of a drug-eluting stent.  Post-procedure angiography demonstrated improved coronary blood flow.  The patient tolerated the procedure well and is being monitored for any complications such as bleeding, hematoma, or restenosis.  The patient will be discharged on dual antiplatelet therapy, including aspirin and clopidogrel, and advised on lifestyle modifications, including cardiac rehabilitation, smoking cessation, and dietary changes to manage risk factors for cardiovascular disease.  Follow-up appointments are scheduled for ongoing monitoring of cardiac function and stent patency.  ICD-10 code I25.10, Atherosclerosis of native coronary artery without angina pectoris, and CPT code 92928-LD, Percutaneous transluminal coronary angioplasty; single vessel, were used for billing and coding purposes.
