Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
In all cases with adequate tissue, an initial Congo red stain is performed before mass spectrometry testing to confirm positivity and pattern of amyloid deposition can be considered when interpreting mass spectrometry results. If initial Congo red stain is positive for amyloid, the 89054 / Congo Red, Stain will always be billed at an additional charge. If initial Congo red stain is negative for amyloid, the 82091 / Amyloid Protein Identification, Paraffin, LC-MS/MS will be cancelled and 9901 / Puchtler's Modification of Bennhold's Stain for Amyloid (Congo Red) will be charged. A pathology consultation is typically not required. If the amyloid subtyping results do not fit the clinical findings, a 70012 / Pathology Consultation may be added if appropriate, upon client approval.
