Summary
Community Mental Health (CMH) providers must now bill directly to the Illinois Department of Healthcare and Family Services (HFS) instead of through the Department of Human Services, effective July 1, 2011. This transition requires providers to update their billing processes, review NPI compliance, and utilize new HFS billing manuals and resources.
Action Required
Immediately (effective July 1, 2011): Community Mental Health providers must transition all billing to HFS instead of DHS. Billing team must: 1) Review and implement updated Community Mental Health Service Definition and Reimbursement Guide for coding changes, 2) Ensure compliance with HFS NPI policies by verifying one-to-one relationship between NPIs and HFS provider numbers, 3) Update internal billing systems with any coding requirement changes, 4) Register for HFS technical assistance teleconferences, 5) Contact HFS Provider Billing Line at 1-877-782-5565 (Option 0) for Community Mental Health Support if needed. Non-compliance may result in billing rejections.
