Injury Episode Data / INJEPSOD.DAT
FIJ
ECODE_1 and ICD9_1
Nine poisoning episode records were accidently left in the 
Injury Episode file.  These poisoning episode records can be 
identified by the following: 1) eight poisoning episode 
records have E codes of E905.0-E905.9 (venomous animals and 
plants as the cause of poisoning and toxic reactions), and 2)
one episode record has an ICD-9-CM code of 987.9 (toxic 
effect of unspecified gas, fume, or vapor).  
These nine poisoning episode records must be removed from 
the Injury Episode file prior to calculating national 
estimates of injuries.  These E codes and ICD-9-CM codes 
can be found in ECODE_1 and ICD9_1.

At the top of page 8, the parenthetical statement "FIJ.051 
to FIJ.295 are asked for each injury episode" gives the 
first question number incorrectly.  The correct question 
number is FIJ.050.
Replace question number FIJ.051 with FIJ.050 in the statement.
