If a patient in hospital has a dialysis session (13100) and then becomes unwell, requiring ICU admission with continuous renal replacement therapy (13885 or 13888) on the same day, can item 13100 be co-claimed on the same day as 13885 or 13888 by the same provider? Can it be claimed by different providers - i.e. 13100 by the nephrologist and 13885 by the intensivist?
