New situation for me…Patient needs either a Urinary Cath change or a SP change. In the past we would provide the catheters, bags etc for these and bill 51702, 51703, 51705 or 51710. Now the provider wants to have the patient bring their own supplies and bill these CPT codes with a Mod 52. Can we do this? Do we bill something all together different? My understanding that these codes include supplies if the change is done in the office. My understanding of Mod 52 is that they would have had to stopped in the middle of the procedure in order to use this modifier which they would not it is just that the patient would bring their own Cath.

Thank you
