I1D-FY DATA LAYOUT
-----------
The I1D-FY.TXT file contains five fields separated by tabs.

Field 1 code: ICD-9 diagnosis code with decimal (3-7 characters long)
Field 2 short: 25-character description
Field 3 long: 80-character description
Field 4 effdate: effective date of the code (year that it was added)
Field 5 expdate: expiration year for the code

NOTE: the year refers to the calendar year, not the coding year. So codes 
effective for the 2007-2008 year (FY 2008 ICD-9-CM) have effective dates of
2007.
