Medicare patient had a left heart cath with PCI. Returns to floor and goes into cardiac arrest. Patient returns to cath lab where a right heart cath is performed with angioplasty. Medicare paid angioplasty but denying right heart cath. This was billed with modifier 26.78.XU. The cardiac codes do have a MUE of 1 but it there is a change in patients condition isnt' a second heart cath allowed on the same day?
