We sent a urine sample to a path lab to do a 88112 - CNS-Cytopathology, selective celluar enhancement tech w/interp. They also charged a 88305 - Level IV surgical pathology, gross & microscopic exam. The lab said they used the 88305 to do a cell block. Myself and other coders that I have talked to do not think this is correct. The 88305 is a biopsy surgical path code. We did not send any tissue only a urine sample to do the CNS (88112)
We believe that the path lab is incorrectly charging the 88305. I would appreciate anyone's input on this.
