CPT Codes 2005 expands 88365-88368
CPT 2005 erased the line in the sand - you should no longer use 88365 only for tissue ISH. Removing the word ""tissue"" from the code definition allows you to report this code for cytology specimens as well.
Nor should you have any more problems reporting ISH tests with a morphometric analysis component (quantitation) because CPT 2005 added two new codes for this service following 88365 (In situ hybridization [e.g. FISH] each probe). The codes distinguish between automated (88367 Morphometric analysis in situ hybridization [quantitative or semi-quantitative] each probe; using computer-assisted technology) and manual (88368 ... manual) ISH quantification.
88365-88368 Now Include Cytology
