There is one for serum/plasma (62238-1) When others encounter these situations, do you use the available code or not map the test and wait for the next release? 2013-10-01 at 14:10 #16678 Pam BanningParticipant Hello, Our experience is to NOT map to a closest code, but rather use that closest code as a basis of a submission to Regenstrief for a new code with different specimen. Instructions are found in the RELMA Manual. Have a great day, Pam Banning Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
