'87147' allows for culture typing per antiserum. If we isolate a Streptococcus and need to use an agglutination method to identify which type of Streptococcus (A, B, C, F or G) is present, can we code 87147 5 times?

I believe not. CPT defines presumptive and definitive identification based on the tests performed to identify the organism, not based on whether you can name the genus, species or subspecies. The introduction to the microbiology section states, “Presumptive identification of microorganisms is defined as identification by colony morphology, growth on selective media, Gram stains, or up to three tests (e.g., catalase, oxidase, indole, urease).”
