On October 1, 2015, the ICD-9 code sets used to report medical diagnoses and inpatient procedures will be replaced by ICD-10 code sets. The transition to ICD-10 is required for everyone covered by the Health Insurance Portability Accountability Act (HIPAA).
ICD-10 will significantly expand the number of medical billing codes from approximately 13,000 codes under ICD-9 to more than 68,000 diagnosis codes under ICD-10. Under ICD-10, the code format changes as well. For example, ICD-10 codes can have a varying number of digits and the digit combinations can change (e.g.,###.##, ##.###.##).
Not being prepared for this transition will have serious financial consequences. Not using the proper diagnostic codes in your claims will result in decreased reimbursements, delays and denials. To be compliant, your information management and billing systems must be updated to translate ICD-9 codes to ICD-10, and you need to allow significant time for internal and external testing.
