Note the possibility of zero-padded sequence number. Excerpt from section 4.4.11, SDTMIG v3.4:

For example, if the type of disease milestone is "EPISODE OF DISEASE UNDER STUDY", the values of MIDS for instances of this type of event could include "EPISODE1", "EPISODE2"; or "EPISODE01", "EPISODE02", and so on.

Also, the stripped sequence number is expected to start with 1. Excerpt from Domain SM assumption 2(b):

Sequence numbers should start with 1 and indicate the chronological order of the instances of this type of disease milestone.

Yes, in this case the suffix is any text after "EPISODE", including a missing suffix ... We'll need the prefix as a required parameter to such a function call.
