A hospital gets paid $xx for a specific ICD-9 code. Medicare and Medicaid reimburse a practice $xx for a given ICD-9. Bills are generated by taking the ICD-9 codes from a chart and summing them with the associated cost. LYNX and SNOMED are other coding types for this purpose, but they are older and are being used less often.
If you had provided the correct information, my questions would not have occured. Half ass answers is what gets most people in trouble.
ICD-9-CM Coding System
The International Classification of Diseases is a system developed collaboratively between the World Health Organization (WHO) and ten international centers, including one in the US. The purpose is promote international comparability of in the collection, classification, processing and presentation of health statistics.
In the US, the system takes on another purpose as the HIPAA-mandated coding system used in medical billing. ICD-9 Clinical Modification (CM) is the system currently used in the US for medical billing purposes. It is more finely grained than ICD-9 alone, including 5-digit codes where ICD-9 does not. The ICD-9 system is updated an annual basis. New codes go into effect on October 1 of each year.
ICD-9-CM contains three "volumes" of information. Volume 1 contains the diagnosis codes that every provider needs for billing. Volume 2 is an alphabetical index of Volume 1. Since computerized searches do the same thing as a printed index, this volume is not useful a data file. Outpatient diagnostic or treatment centers, like physician offices, need only Volume 1. Volume 3 contains procedure codes, which are used for billing inpatient hospital stays in the DRG system.
ICD-10-CM is not expected to become a HIPAA mandated coding system until 2009. However, the draft system is available in educational volumes and as draft ICD-10-CM and draft ICD-10-PCS data files.
