The ICD-10 Virtual Code Book provides the clinical terms and/or disease/condition names to search for correct and specific ICD-10-CM codes.The transition from ICD-9 to ICD-10 goes hand in hand with the goal of healthcare reform to improve quality and decrease the cost of care. With more than 171,000 codes as compared to just under 18,000 in ICD-9, ICD-10 will provide a much more accurate method of describing the care provided. The transition will have a far-reaching impact on virtually all healthcare workers, from physicians and clinicians to medical coders to clerical employees. Educating and training these employees is vital to preparing for the transition to ICD-10 for both hospitals and physician practices.
