"...presents for cystometrogram and pressure flow studies...evaluation demonstrates a first sensation at 86 cc ith first urge at 121 and capacity at 200. No uninhibited contractions are identified. Flow rate not recorded. Evidence of emptying is uncertain." A graph is part of the documentation with columns for volume, flow,VH2O, Pdet, Pabd, Pves and rows for cough, first urge, capacity, first sensation. The doc is coding this 51726 and 51797, however I think 51729???? Could anyone weigh in on their thought?
