Possible online services disruption due to Internet related outage

A worldwide technology outage is causing disruption to some State of Illinois online systems.  We are aware of this issue and are diligently working on restoration.

Paper Claims Rejecting Incorrectly

HFS System Issue:

Paper claims are rejecting incorrectly for N01, Invalid First Diagnosis code, N02, Invalid Second Diagnosis Code, for dates of service prior to 10-01-15. 

Paper claims are rejecting incorrectly N05, First DX not From ICD-CM for dates of service after 10-01-15.

Problem:

Valid ICD-9-CM codes are required on claims for dates of service prior to 10-01-15.  Valid ICD-10-CM codes are required on claims for dates of service on or after 10-01-15.  Paper claims with valid diagnosis codes for the Date of Service are rejecting inappropriately with HFS Error Code N01, N02, and/or N05.

Non-Institutional providers billing on paper claims forms.
