when looking for giardia organisms in a duodenum biopsy is a trichrome stain an 88312 or 88313

SuperCoder Answered Wed 12th of March, 2014 10:32:12 AM

Codes 88312 (special stains; group I for microorganisms, each) and CPT 88313 (special stain; group II, all other, [e.g., iron, trichrome], except immunocytochemistry and immunoperoxidase stains, each) are used to report special stains. Determining the correct code depends upon the specimen and the reason for the pathology examination. If the reason for the stain is microorganisms, use code 88312. The types of stains found within the parenthesis in the description of these codes in CPT are to provide examples only.
