The new code set will quadruple the diagnostic codes you can choose from. You-re busy updating your diagnosis coding to incorporate the ICD-9 2009 changes -- and you only have three years left until the ICD-9 series is replaced by the new, overhauled ICD-10 codes, according to a recent HHS announcement. Brace Yourself for Major Changes The Department of Health and Human Services (HHS) delivered a whammy in August with its announcement that ICD-10 codes aren't too far away. On Aug. 15, HHS announced its proposal to replace the ICD-9 codes with the ICD-10 series effective Oct. 1, 2011. The plan: Not only would the new code set completely overhaul your claims systems, software, and superbills -- but it could require significant training for you as a coder. Here's why: The ICD-9 code series includes 17,000 codes. The ICD-10 code set, however, contains over 155,000 codes that you-ll have to wrap your brain around if it's implemented as HHS hopes it will be. Many medical practices were surprised by the news of the impending ICD-10 implementation, despite the fact that CMS has been building the new code set for years. "We-ve been thinking of ICD-10 as this faraway prospect that may never take hold," says Heather Corcoran with CGH Billing. "The new announcement sort of brings us back to the reality that this will indeed take effect." Experts Lament the Impact of ICD-10 "What this means is massive changes to all computer bases and programming and charge masters and codes," says Quin Buechner, MS, M. Div, ACS-FP/GI/PEDS, CPC, CCP, CMSCS, of ProActive Consultants in Cumberland, Wis. "Nothing [presently] in existence can be used. Coders will need to be retrained and retested for certification. The expense for small and even medium practices could be so overwhelming, they-d need to close or sell out." "We recognize that the transition to ICD-10 will require some up-front costs, but each year of delay would create additional costs, both because of the limitations of ICD-9 and because of the need to employ the greater precision that ICD-10 codes provide to support value-based purchasing of health care and other initiatives," said CMS Acting Administrator Kerry Weems in a statement. Who else is speaking out: Many healthcare organizations have come forward to add weight to the arguments against the 2011 implementation date. The Blue Cross Blue Shield Association, for example, says that the proposed timeline is "completely inadequate" and "unworkable."

Example: Right now, you should report 733.00 for "Osteoporosis, unspecified." With ICD-10, you-ll report M81.8 (Other osteoporosis without current pathological fracture). Notice you-ll have to know the patient does not have a pathological fracture.
