Wiki Claim for peritoneal dialysis denial

[debiwill]

I have had a claim for peritoneal dialysis (90966) denied by Noridian medicare for "missing or invalid modifier". I've not heard we need a modifier for this. I've researched the Noridian medicare website, but haven't found a modifier that my provider should be using. Any help would be appreciated! Thank you!

Global period?

Is the patient - by any chance - in the global period for some other major surgery?

Just grasping at straws ...

Hope that helps.
