Non-Institutional claims are subject to a timely filing deadline of 180 days from date of service.
Timely filing applies to both initial and re-submitted claims.
Durable medical equipment and supplies (DME) identified on the DME fee schedule as not covered by Medicare are subject to a 180 day timely filing requirement and must be submitted to the Department within 180 days from the date of service. DME items that are covered by Medicare in certain situations should be submitted to Medicare and the Medicare timely filing guidelines listed for Medicare payable claims would apply.
Claims addressed to a HFS post office box are received M-F between 8:30 am and 5:00 pm at a distribution center for further sorting and delivery to specified locations/units. Upon arrival at the Bureau of Claims Processing, paper claims are assigned a document control number (DCN) within 24 hours. The first 7 numbers of the DCN represent the Julian date the claim was received. If the claim must be routed to a different unit for special handling, the paper claim will be physically date stamped on the day it is received in the unit. Timeliness of override requests received in the Bureau of Professional and Ancillary Services is determined by the date stamp.
Timely filing override requests for any exceptions that require a manual override must be submitted with an original paper claim form and any attachments to the following address (unless otherwise noted):
Healthcare and Family Services
Bureau of Professional and Ancillary Services
Attn: Billing Consultant
P.O. Box 19115

- Replacement or Void/Rebill of an entire claim or single service line – The Department will accept electronic transactions submitted through MEDI or via 837P files to void or replace a paid claim (includes claims paid at $0), or a claim that is pending to pay, if submitted within 12 months from the original paid voucher date.
NOTE: The functionality of allowing replacement claims and claims to be re-billed following a void is for the purpose of correcting errors on previously submitted and paid claims (e.g. incorrect provider number, incorrect date of service, incorrect procedure code, etc.) and NOT for the purpose of billing additional services.
- Replacement claims – To replace a single service line or entire claim, enter Claim Frequency “7”. Detailed instructions on how to replace a claim electronically can be found in the Chapter 300, 837P Companion Guide. This method is preferred as it requires no manual override.
- Void & Re-bill – This process involves two steps. The void portion may be completed electronically or on paper. Please refer only to step #1 for a void with no re-bill.
- To electronically void a single service line or an entire claim, enter Claim Frequency “8”. Detailed instructions on how to void a claim electronically can be found in the Chapter 300, 837P Companion Guide. A paper void may be completed by submitting a NIPS Adjustment Form HFS 2292. Instructions on how to complete the form are located in Chapter 100, Appendices.
- Following completion of the void, a new original claim must be submitted within 90 days of the void DCN and may require manual override. If manual override is required, attach form HFS 1624, Override Request Form, stating the reason for override to a paper claim. Community Mental Health Providers (provider type 036) who do not have a paper billing option should contact a billing consultant for override instructions.
