All providers and hospitals covered by the Health Insurance Portability and Accountability Act (HIPAA) are now required to use the new International Classification of Diseases, 10th Edition (ICD-10), which is a diagnosis and procedure coding system. Current Procedural Terminology (CPT) codes, which are usually used when claims for health care services are reported to workers’ compensation and no-fault insurers, are not affected by ICD-10. The New York Workers’ Compensation Board made the change to ICD-10 in order to be consistent with both Medicare and Medicaid, and to avoid the costs of supporting two diagnostic coding systems.
