ABNs Are Being Used More Frequently – Required for Non-assigned Claims? Maybe.

Does Medicare require ABNs for non-assigned claims? The quick answer is MAYBE – depends on the situation. Let’s start with some misconceptions in the industry about non-assigned claims. 

One misconception is that a supplier has no financial liability and needs to get an ABN for non-assigned claims. Essentially, non-assigned means that the supplier is not accepting the Medicare fee schedule because the reimbursement is too low. 

The explanation the supplier provides on an ABN for a non-assigned claim cannot be “claim is being submitted as non-assigned.” With a non-assigned claim, there still is financial liability, meaning the supplier needs to make sure the coverage criteria has been met according to the medical policy. If the coverage criteria is not met, this is when an ABN is implemented whether it’s an assigned claim or a non-assigned claim.

The purpose of an ABN is to inform a beneficiary in advance of the reason Medicare may not pay for the service being provided. If the supplier puts “claim is non-assigned” as the reason for denial on the ABN, it’s not a valid reason and will be denied in an audit. ABNs are used for the following situations:

  • Lack of medical necessity
  • Same or similar equipment
  • The quantity exceeds the allowed amount
  • Upgrades (not within the same code)

Remember, the ABN speaks to the beneficiary, making sure they understand the information documented on the form. The ABN allows the beneficiary to make an informed, consumer decision about whether or not to receive the services for which they may have to pay out of pocket.

ABNs do get audited. If not used properly and completed as instructed, an ABN will cause an unfavorable decision in an audit. Be sure to review the ABN instruction manual with your staff.

Member Q&A From The van Halem Group: New Order Requirement and Member Q&A From The van Halem Group: New Order Requirement and "Master List" I'm curious about this new order requirement. I see that Medicare updated the notice on 2/12/20, and I'm curious about the “Master List” of items that still needs a WOPD. I'm wondering if PAP equipment and supplies fall under the SWO or the WOPD. Can you help me understand? The Cost of Compliance – An Impassioned Plea to be Proactive thumbnail The Cost of Compliance – An Impassioned Plea to be Proactive Last year, The van Halem Group was engaged by several DME providers that were subject to a 6-year OIG lookback audit. Sadly, for companies that did not have a process in place for proactive chart audits, the 6-year look back resulted in a very expensive lesson. Lookback audits are here to stay, and it's never been more important for providers to have a comprehensive proactive compliance program, and this is one way that The van Halem Group can assist members. OIG to Review PMD Repairs and PAP Supplies thumbnail OIG to Review PMD Repairs and PAP Supplies The Office of Inspector General (OIG) has updated its work plan to include new reviews for PAP replacement supplies and power mobility device repairs. In a recent article from HME News, Medicare paid approximately $945.8 million for replacement supplies in 2017 and 2018, but OIG has previously found that most claims did not comply with Medicare requirements and that DME suppliers often did not have the documentation required to support the need for replacement supplies.

Since 2010, the CMS's Comprehensive Error Rate Testing (CERT) program has identified nebulizers and related drugs (i.e., inhalation drugs) among the top 20 supplies with the highest improper Medicare payments. Based on prior reviews, the Office of Inspector General (OIG) conducted a nationwide review to determine if the suppliers included in the review complied with Medicare requirements when billing for inhalation drugs.
