The enclosed Score Card is the fifth in the ICIS injury series and provides detailed data and graphics on California work injury claims involving degenerative, infective or metabolic joint disorders . Based on CWCI Industry Claims Information System (ICIS) data, these injuries account for 3% of job injuries in California, but almost 6% of workers’ compensation payments, as treatment plans for these injuries rely heavily on radiology, physical therapy and surgery, and a quarter of these injuries result in a permanent disability – double the proportion noted for all work injuries.
