Laboratory Coding Update for 88364/88347
June 25, 2014CPT codes 88346 and 88347 (immunofluorescent study, each antibody, direct method/indirect method, respectively) are now on manual review if more than one unit is reported. Reporting of multiple units requires documentation of multiple specimens. This change is based on the 2014 NCCI Policy Manual, which includes the following instructions: “If a single antibody staining procedure for one or more antibodies is performed on multiple blocks from a surgical specimen, multiple slides from a cytologic specimen, or multiple slides from a hematologic specimen, only one service may be reported for each separate specimen.”
