Tip: Help your patients get their MBIs ASAP. In less than a month, the feds will reject Medicare claims with patients’ old HICNs. It’s crunch time — start using MBIs now! Reminder: Starting on Jan. 1 — no matter the date of service — the Centers for Medicare & Medicaid Services (CMS) will reject claims with the old Health Insurance Claims Numbers (HICNs), with a few exceptions. The transition comes to a close on Dec. 31, and providers should be using patients’ new Medicare Beneficiary Identifiers (MBIs) on their claims submissions as of Jan. 1. Remember, CMS initiated the change to move away from Social Security numbers on Medicare beneficiaries’ cards starting in April 2018. The move to replace the old cards with randomly-selected, 11-digit MBIs was made to protect patients from identity theft and fraud. The most recent statistics show that 86 percent of providers are using the new numbers in their claims submissions, notes a Dec. 3 special edition of MLN Connects. According to guidance from Part B Medicare Administrative Contractor (MAC) CGS Medicare, you can expect these notices on Jan. 1: Review the Exceptions FFS exceptions: For Fee-for Service (FFS) claims, there are five exceptions to the MBI rule. You can still submit claims with an HICN for the following reasons: Medicare plans: According to CMS, there are a few exceptions for Medicare plans, too. It’s acceptable to use HICNs for plan appeals. You can also use them for “Drug Data Processing, Risk Adjustment Processing, and Encounter Data” adjustments, advises the agency. Currently, CMS intends to use HICNs for incoming and outgoing reports on things like Provider Statistical reports, Accountable Care Organization (ACO) reports, and others “until further notice,” guidance indicates. Plans can also use HICNs for older contract years as well. See more details and advice on helping patients get their MBIs at www.cms.gov/Medicare/New-Medicare-Card/index.
