ICD-10 is a diagnostic coding system implemented by the World Health Organization (WHO) in 1993 to replace ICD-9, which was developed by WHO in the 1970s. ICD-10-CM is scheduled to replace ICD-9-CM, our current U.S. diagnostic code set, on Oct. 1, 2013. Medical science keeps making new discoveries, and there are no numbers to assign these diagnoses. ICD-9 is out of room because the classifications are organized scientifically and each three-digit category can have only 10 subcategories. Most numbers in most categories have been assigned diagnoses.
ICD-9-CM Volume 3 is not typically used in physician office billing. Volume 3 of ICD-9-CM is specific to procedure codes used in hospitals for inpatient procedures, while physician offices typically use Volume 1 for diagnosis codes. CPT and HCPCS codes are more commonly used for physician office billing.
