any condition classifiable to 414.1-414.9 specified as acute or with a stated duration of 8 weeks or less
The following fifth-digit subclassification is for use with category 410:
0 episode of care unspecified
Use when the source document does not contain sufficient information for the assignment of fifth-digit 1 or 2.
1 initial episode of care
Use fifth-digit 1 to designate the first episode of care (regardless of facility site) for a newly diagnosed myocardial infarction. The fifth-digit 1 is assigned regardless of the number of times a patient may be transferred during the initial episode of care.
2 subsequent episode of care
Use fifth-digit 2 to designate an episode of care following the initial episode when the patient is admitted for further observation, evaluation or treatment for a myocardial infarction that has received initial treatment, but is still less than 8 weeks old.
