This was a retrospective database analysis (2001-2009) of employees' medical, prescription drug, and absence costs and days from sick leave, short- and long-term disability, and workers' compensation. Employees with an ICD-9 diagnostic code for back or neck pain and an ICD-9 for a back- or neck-related neuropathic condition (eg, myelopathy, compression of the spinal cord, neuritis, radiculitis) or radiculopathy were considered to have nociceptive back or neck pain with a neuropathic component. Employees with an ICD-9 for back pain or neck pain and no ICD-9 for a back- or neck-related neuropathic condition or radiculopathy were defined to have nociceptive back or neck pain. ⋯ Medical, short-term disability, and prescription drugs yielded the highest incremental costs compared to controls. Mean total absence days/year were 8.26, 7.86, 5.70, and 3.44, respectively. The economic burden of back pain or neck pain is increased when associated with a neuropathic component.
