Wiki Billing Cathcare Maintenance for Medicare Denial

[wendysimpson]

Has anyone on this forum billed for Cathcare Maintenace DENIAL to Medicare? I have been instructed by several Managers over a period of time to bill three (3) different ways: 1) use A4223 with a GY modifier 2) A4221 with GY modifier and put a description in Box 19 "Cathcare Maintenance - No active infusion". But this code is for 1 unit weekly. Don't see a problem billing for Implanted port with this code since Implanted Ports are flushed either 1 per month or twice per month or once weekly; but for single DL, TL lines would be a problem since we bill 1 unit per day. 3) A9270 with GY modifier. (The only time this code has been used is in our DME Medical department, not infusion). Would appreciate some input by other infusion billers that bill Medicare.
