PRP injection in office

What CPT code is correct to use when a patient is getting a PRP (plasma rich platelet) injection in the office?

I've looked at a few forums and websites and I keep coming up with 0232T (effective 7/2010). But I've also seen some answers saying to use 36514 and 20600-20610. These are the codes one of my offices is pushing back with to use.

Any help is GREATLY appreciated!

Thanks
