The following is an excerpt from our recently published ICD-10 Survival Guide:
"Employed in the United States since 1978, ICD-9 became significantly outdated with the rapid diagnostic, medicinal, surgical and technological advances of the past several decades. Dr. Joseph C. Nichols Jr., an orthopedic surgeon and expert in health information technology, conducted a relatively recent study -- which included three years’ worth of data from an insurance company on one million lives. Dr. Nichols found that 72.5% of the charges were coded using a meager 5% of the ICD- 9 codes. Moreover, the codes were either mainly symptom-type codes or just highly unspecified and vague.
On the other hand, ICD-10 is far more specific and detailed in its representation of the patient’s healthrelated condition, taking into consideration degree of severity, complexity and risk; laterality; comorbidities; complications; and other vital parameters relevant to the complete and accurate diagnosis and treatment of the patient.
In the United States, ICD-10 breaks down into two major components:
- ICD-10-CM (Clinical Modification)
- ICD-10-PCS (Procedure Coding System)"
