ICD-10-CM Diagnosis Codes
The International Classification of Diseases, 10th Edition, Clinical Modification/Procedure Coding System (ICD-10-CM/PCS) will enhance accurate payment for services rendered and facilitate evaluation of medical processes and outcomes.
The new classification system provides significant improvements through greater detailed information and the ability to expand in order to capture additional advancements in clinical medicine.
ICD-10-CM - The diagnosis classification system developed by the Centers for Disease Control and Prevention for use in all U.S. health care treatment settings. Diagnosis coding under this system uses a different number of digits and some other changes, but the format is very much the same as ICD-9-CM.
The U.S. Department of Health and Human Services (HHS) has mandated industry-wide adoption of ICD-10-CM and ICD-10-PCS code sets by Oct. 1, 2011. ICD-10-CMS will affect all components of the healthcare industry. Ambulatory surgery centers (ASCs) will not be affected by ICD-10-PCS unless they are utilizing ICD-9-CM volume 3 for inpatient procedures.
The two major changes in the ICD-9-CM to ICD-10-CM code sets are structure and detail. The codes will move from a numeric five-character size to an alphanumeric seven-character size. At current count, there are approximately 17,000 ICD-9-CM codes and the possibility of 155,000 ICD-10-CM/PCS codes. The codes are far more specific which will allow for greater accuracy.
