Compliance, payment, and ICD-10 hang in the balance. Say goodbye to forms 4010/4010A1 for electronic transactions starting Jan. 1, 2012. That's the date your clinical laboratory or pathology group will need fully functional form 5010 to comply with the Health Insurance Portability & Accountability Act of 1996 (HIPAA) electronic transaction standards. If you don't have your 5010 glitches worked out by that date, you won't be able to submit electronic transactions to Medicare. Get Ready for ICD-10 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 5010 Glitches Experts who are working with the 5010 conversion are alerting others to some common pitfalls you should prepare for. Fixing P.O. box is up to you: Notice that the "pay to" address can continue to be a P.O. box. "The problem is that some of the low-end systems don't have a place for two addresses," Burleigh says. Laboratories that maintain lockboxes with P.O. box addresses but who don't have the ability to fill in two different fields will either have to give up lockboxes so claims won't reject, or use the lockbox address and face claim rejections. Solution: Rectify patient information, too: New remark codes: Who's Affected? The transition to 5010 is not just for labs that deal with Medicare. Some payers are even going active with version 5010 in August of this year, Brink says. "Either directly or indirectly, HIPAA Version 5010 will impact nearly everyone involved in healthcare transactions -- providers, clearinghouses, and payers, as well as vendors who provide practice management (PM) systems and other transaction-related software(s)," says Kim Dues, CPC, owner of Mass Medical Billing Services in Dickinson, Tex. "It is mostly a complex technical issue for those on the business and administrative side -- although, if the implementation doesn't go smoothly, it will affect all." Caution:
