Acute Myocardial Infarction (Hospital A) Transferred to Hospital B for Coronary Intervention

The patient was transferred to Hospital B following a one-week stay in Hospital A for an acute inferior wall myocardial infarction (MI). At hospital B, the patient continued to receive treatment for the MI, cardiac catheterization was performed, which demonstrated occlusive disease in the left anterior descending artery with 99% narrowing and coronary artery bypass grafting was carried out.

Article Overview

This article reviews a transfer-of-care inpatient coding scenario involving acute myocardial infarction management across two hospitals, with coronary catheterization and bypass surgery at the receiving facility. It is intended for coders, HIM staff, and auditors who need to understand how transfer cases are discussed in hospital diagnosis sequencing and related inpatient coding guidance.

Why This Topic Matters

Transfer cases can affect principal diagnosis assignment, which influences inpatient record interpretation and downstream reporting. The article helps readers recognize the kind of hospital coding issue presented when treatment continues after transfer.
