I have coded 64493 for a lumbar pars injection. the diagnosis code is lumbar pars defect. but that does not meet medical necessity for 64493. Is this the correct cpt code

The pars interarticularis links the posterior part of the vertebrae (facet joint) to the anterior body of the vertebrae. Because of this location, a pars defect injection technique is similar to a facet joint injection. Many providers report it as a facet joint injection, with 64493
A pars defect may be congenital (756.11, Spondylolysis, lumbosacral region) or due to trauma, stress or sports injuries (738.4, Acquired spondylolisthesis). Verify this patient's situation before reporting the diagnosis codes for medical necessity.
