Washington rates for HCPCS 22634

Fuses one more level of the lower spine during the same operation, joining an additional pair of vertebrae so they heal together into one solid segment. It is billed in addition to the main procedure, and applies when more than one level of the lower back needs to be fused. Fusing an extra level stops movement there, which is done when more than one worn or unstable level is causing symptoms.
