We know that the documentation of a “percentage” with an IHC stain would support that a quantitative approach was taken to evaluate the stain.
The IHC code selection has to be supported based on the pathologist’s work performed and what is documented in the final report
Can I please get some clarity regarding my scenarios:
1. Reporting > or < 5% Ki-67 reactivity in Mart-1 positive dermal melanocytes in a Ki-67/Mart-1 multiplex stain. Is there a code that bills for quantitative in a multiplex stain.
In this example we have a percentage for Ki-67, but the later Mart-1 is a Positive. Would this stain be coded 88344 or 88360?
Another example:
2. PRAME stain currently reported as 0 (0% staining), 1+ (1 to 25% staining), 2+ (26 to 50% staining), 3+ (51-75% staining), or 4+ (76-100% staining) with 4 + indicating overexpression supportive of melanoma.
Would this be coded as 88342 or 88360?
