I have a pressing questions for all ortho coders....

If a provider takes an x-ray of the patient's left foot and then takes an x-ray of the patient's right foot for comparison reasons (no other reason just a comparison), can you report the comparison x-ray?

I read in an orthropedic manual from Ingenix that comparison x-rays that are done in the absence of medical necessity (no signs/symptoms) are considered screening by Medicare and are not payable. Does anyone know this to be true and can you point me to a specific guidance from CMS that states this?

Also, would you use modifier 50 for the comparison x-rays, or just LT, RT?

Thoughts?

Comparison reviews are not billable--they lack medical necessity. Truthfully, I cannot locate CMS guidance, but check out the ACR website for further guidance.
