Wiki In patient ICD-9 Coding

[AMettler]

I am new with inpatient coding. I know the new ICD-9 codes take effect 10/01/08, but if the inpatient stay begins 9/27/08 and ends 10/05/08, do you use the 2008 codes or the 2009? Does present on admission mean that one would use the codes effective on the date of admission?

I believe you would utilize the codes effective on date of discharge.

That sounds right to me as well since typically that is when you know the discharge diagnosis, procedures, etc.

I don't have any documentation to back this up, but that would be my best guess.

Diagnostic codes are used based on the date of discharge.

If you have a good ICD-9, it should be stated in the guidelines.

Good luck & hope this helps.
