Providers need to continue to send bills, reconsideration requests and supporting documentation to MSF. The process for requesting re-evaluation or reconsideration remains the same. If you are requesting a re-evaluation or reconsideration of a denied or partially denied bill, please send a copy of the CorVel or ACS Explanation of Review (EOR) with the necessary documentation or information to:

Montana State Fund
PO Box 4759
Helena, MT 59604-4759
FAX: 406-495-5020

ACS will be processing re-evaluation or reconsiderations of CorVel bills after 1/2/12. The ACS EOR will reflect the original CorVel bill number, as well as an ACS number, for cross reference purposes.

If you are sending a corrected bill that was previously evaluated by Corvel (e.g., to correct a code, add information in CMS 1500 Boxes 31-33, or specify # units, etc.), please write “Corrected Claim” on the bill, attach a copy of the CorVel EOR and mail or fax to the above address. If you are unsure of what is needed to reprocess an older bill, please contact a member of the Medical Team at 406-495-5011.

Payment Status
Please allow 30 days before calling for a payment status for a bill or reconsideration request. Most bills are processed within 30 days or returned to the provider requesting missing information. Even during the transition period, we hope this will be the case. However, some bills may be delayed during the transition period.
