The health care industry will switch to ICD-10 on October 1, 2013. Encounters and discharges occurring before October 1, 2013 will use ICD-9, and those occurring on or after that date will use ICD-10. The final rule suggests that compliance activities (gap analysis, design, development, internal testing) should begin in January 2011.
The fundamental driver for ICD-10 is financial - - the inability for ICD-9 to support the growing number of high-priced medical procedures. For more on this, see "More Painful than an Insect Bite? ICD-10 Cost-Benefit for Healthcare Providers".
According to HHS, ICD-10 will:
- "Support value-based purchasing and Medicare’s anti-fraud and abuse activities by accurately defining services and providing specific diagnosis and treatment information;
- Support comprehensive reporting of quality data;
- Ensure more accurate payments for new procedures, fewer rejected claims, improved disease management, and harmonization of disease monitoring and reporting worldwide; and
- Allow the
United Statesto compare its data with international data to track the incidence and spread of disease and treatment outcomes..."
In a bit of a stretch, HHS contends that "ICD-10 will also improve claims processing and payment, and, through the use of health care technology that utilizes ICD-10, assist health care practitioners in making treatment decisions by more precisely matching diagnoses and procedures to the appropriate code. For example:
- Pressure ulcers are a common condition in elderly Medicare beneficiaries with chronic illnesses. Under the current ICD-9-CM system, health care practitioners can identify the severity or location of a pressure ulcer but the coding system cannot link those elements if the patient has more than one ulcer. Under a single ICD-10 code, a patient’s medical history will identify the severity and location of each pressure ulcer;
- ICD-9 has only one code for angioplasty, the widely used procedure for widening a narrowed or obstructed blood vessel. ICD-10 provides 1,170 coded descriptions, with a granularity that pinpoints the location of the blockage and the device used for each patient;
- ICD-9 codes do not provide sufficient detail to distinguish whether a condition occurred on a patient’s left or right side. ICD-10 will improve care by providing that basic type of information; and
- ICD-9 includes separate codes for medication errors and other external causes of injury, which are reported separately from the actual condition. Under ICD-10, information about medication errors and external causes of injury will be embedded in the code for the condition. Therefore a single, more informative code will provide a ready source of information to help medical professionals prevent medical errors and improve quality of care."
CDC and CMS are good sources of information on ICD-10-CM and ICD-10-PCS guidelines and cross-mappings, even including a mapping from ICD-10 (international) to ICD-10 (U.S.).
The NCPDP standard for electronic pharmacy-related transactions is upgraded to version D.0 to better support Medicare's Part D prescription drug benefit claims processing, including coordination of benefits. The compliance data is also January 1, 2012. In addition, Version D.0:
- "Provides more complete eligibility information for Medicare Part D and other insurance coverage;
- Better identifies patient responsibility, benefits stages, and coverage gaps on secondary claims; and
- Facilitates the billing of multiple ingredients in processing claims for compounded drugs."
CMS estimated costs and benefits as follows (click on the picture to expand):
Eight years after the original HIPAA rule was issued, use of electronic transactions remains stubbornly and abysmally low (see Healthcare's Indefensible Administrative Costs). This suggests a major industry challenge in updating the electronic transactions and preparing for cutover to ICD-10.
Systems changes will be required across the health system to accommodate the coordinated cutover of the electronic transactions. Then, on a single date for the industry, process and system changes will go into effect to support two code sets (ICD-9 for events before the date and ICD-10 after). Many systems will require iterative major upgrades to effectively support these requirements, each with full deployment to their customer base in fairly tight timeframes.
This suggests a level of execution and capability that has only happened once before. That event was Y2K - - which caused one CEO to ruefully recount how he gave his CIO an unlimited budget, yet the CIO managed to exceed it. And which will now cause healthcare technology companies to ponder how they avoid a repeat of the sales collapse that immediately followed.
