Parsing strategy for unrolling the lists. | |
lists are either CPTs or LOINCs | |
CPTs are \d{5}. | |
Loincs are \d{4,5}-\d | |
Particular, problematic list is: | |
14646-4, 2085-9, 35197-3, 12772-0 (electrophoresis, prop is Acnc) 49130-8 (electrophoresis, prop is MCnc) 18263-4 (system is ser/plas. ultracentrifugate) (updated 11/2013) | |
we want (code)(optional parenthetical)--any number of same. | |
