Update on New SNF Edits

CMS Set to Implement New Common Working File Edits to Identify Ambulance Services Provided in Connection with Outpatient Hospital Services that should be bundled to the SNF under Consolidated Billing.

In a Member Advisory issued last week, the AAA provided an update on a series of new Common Working File (CWF) edits intended to identify ambulance transports furnished in connection with outpatient hospital services that are properly bundled to the skilled nursing facility under the SNF Consolidated Billing regime. These new edits are set to go into effect on April 1, 2019. 

In our discussion of the implementation specifics, we attempted to answer the question of what would happen when an ambulance claim is submitted prior to the receipt of the associated hospital outpatient claim, and where the associated hospital claim eventually hit Medicare’s system. Specifically, we indicated as follows:

“The Transmittal contains further instructions that the CWF be updated to identify previously rejected ambulance claims upon receipt of an associated hospital claim for the same date of service that contains an Exempted Code.  Once identified, the Shared System Maintainer (SSM) is supposed to adjust the previously rejected or denied ambulance claim.  At this point, the nature of that “adjustment” is unclear, i.e., it is unknown whether the SSM will automatically reprocess the ambulance claim for payment.  The AAA is seeking additional clarification from CMS on this important point.”

On March 15, 2019, CMS responded to our request for clarification. Specifically, CMS indicated that it has instructed the SSM and/or its Medicare Administrative Contractor (MAC) to automatically reprocess claims that were rejected for lack of an associated hospital outpatient claim.

Upon reprocessing, the claims will pass the edits to the extent the associated hospital claim contains a HCPCS or CPT code that indicates that the hospital outpatient service was excluded from SNF Consolidated Billing. Such claims would then be forwarded to the MAC for further editing, and either paid or denied. By contrast, when the associated hospital outpatient claim contains HCPCS or CPT codes that suggest the hospital services should be bundled to the SNF, the claim will be reprocessed and denied by the MAC with a remittance advice code indicating that the SNF is financially responsible.

AAA Webinar on New SNF Consolidated Billing Edits

March 27, 2019 | 2:00 PM Eastern
Speakers: Brian Werfel, Esq.
$99 for Members | $198 for Non-Members

Join AAA Medicare Consultant Brian Werfel, Esq., to go over the new SNF Consolidated Billing edits that go into effect April 1, 2019. These edits are being implemented by CMS in response to 2017 investigation by the HHS Office of the Inspector General that determined that CMS lacked the appropriate claims processing edits to properly identify ambulance transports provided in connection with hospital outpatient services that are not expressly excluded from SNF PPS. The implementation of these new edits will force ambulance providers and suppliers to rethink their current claims submission processes for SNF residents. Ambulance providers and suppliers will need to make a decision on what to do with these claims moving forward. Sign up today to make sure your service is ready!
