You're not too late to prepare for the Jan. 1 deadline, experts say. The drop-dead date for implementing Health Insurance Portability & Accountability Act of 1996 (HIPAA) version 5010 is less than two months away. If your practice isn't ready, there's no time to lose. Here's what you need to know to stay compliant and avoid financial nightmares. Question 1: What Is Version 5010 Anyway? Version 5010 lays out the technical electronic standards mandated for HIPAA transactions -- that includes claims, eligibility inquiries, remittance advice, and payment data using ICD-10. The current version -- 4010/4010A1 -- does not accommodate the ICD-10 code set. That's why CMS will require version 5010 for use by all HIPAA-covered entities (providers, health plans, clearinghouses, and their business associates, including billing agents) as of Jan. 1, 2012. Timeline: Beware: The last day CMS will accept a 4010A1 form will be Dec. 31, 2011. As of Jan. 1, 2012, if you aren't using the 5010 form, you'll "lose the ability to receive eligibility data from Medicare," said Veronica Harshman of CMS's Division of Medicare Billing Procedures during an Open Door Forum last year. In other words, she noted, mandatory compliance of the 5010 form will begin on Jan. 1, 2012. Question 2: What Happens If We Don't Comply? If you don't have your 5010 glitches worked out by the implementation, you won't be able to submit electronic transactions to Medicare or other payers and you'll quickly lose money. "It will be an operational disruption to your business model," says Kim Dues, CPC, owner of Mass Medical Billing Services in Dickinson, Tex. "What is that in layman's terms? It means no money! Payer by payer you will get denial message and your money will dry up!" "Doctors and other healthcare providers that have done nothing to comply with 5010 should prepare for cash flow issues," says Cyndee Weston, executive director of the American Medical Billing Association in Davis, Okla. "Even those that have tested and completed implementation should be prepared for technical glitches that might disrupt cash flow." Note: Pointer: CMS defines "small providers" as those with less than 10 full-time employees, including physicians. Those practices can apply for the ASCA waiver, which would preclude them from having to file electronically. To apply for an ASCA waiver, visit www.cms.gov/ElectronicBillingEDITrans/07_ASCAWaiver.asp or your MAC's Web site. Don't miss: Question 3: Is It Too Late To Prepare? No, it isn't too late. While you may be behind in the testing phases, you should start now before it does become too late. Get started: Dues says. "Start today." See page 86 for a checklist on what you should be doing right now to get ready. Warning: For more information on HIPAA 5010, visit www.CMS.gov/Versions5010andD0.
