When we have one physician(#1) bill a 88342 for his interpretation of a stain and then another physician (#2) does a different stain interpretation on the same specimen, would you code the 2nd physician as an 88342 or 88341? The description indicates 88342 is for the initial single antibody stain (which was done by physician #1) but the additional single antibody stain (88341) was done by physician #2.
