Fifth Digits for Acute Myocardial Infarction Transfers to Long-Term Care Hospital (LTCH)
We would like clarification regarding the correct use of the fifth digits for myocardial infarctions (MIs) in the long term care hospital (LTCH). Does the initial episode of care for MIs only include time spent in short term acute care hospitals? When the LTCH is licensed under acute care, would an acute myocardial infarction (AMI) that occurred in an acute care hospital that has not resolved under 8 weeks old have a fifth digit of “1†in the LTCH? Does it matter if the AMI was not resolved or resolved? Does a discharge/transfer from short-term acute care hospital to a LTCH make the MI fifth digit a “2� ...

Article Overview
This article discusses guidance related to myocardial infarction coding when a patient is transferred from a short-term acute care hospital to a long-term care hospital. It is aimed at coding professionals who need help understanding how care setting and transfer status relate to diagnosis coding for myocardial infarction cases. The article focuses on the scope of the episode of care and the general transfer-related questions raised by LTCH billing and documentation.
Why This Topic Matters
Accurate diagnosis coding for myocardial infarction depends on understanding how the care episode is defined across facilities. This is especially important when a patient moves between acute care and LTCH settings, where coding and sequencing questions can affect claim accuracy and consistency.
