With the ARIDOL-specific J-code in effect, office-based physicians who would like to use the dry powder bronchial challenge test and providers who currently use ARIDOL have a product-specific code to submit to payers which often increases the efficiency of the reimbursement process," said Stephen Beckman, President, Pharmaxis, Inc.
