According to MLN Matters® Number MM8776 two new HCPCS Q codes have been created for reporting certain drugs and biologicals in the hospital outpatient setting. As you may know Q codes are codes given by CMS on a temporary basis. The new codes are effective for services furnished on or after July 1, 2014.
Also listed in MM8776 are newly added C codes. HCPCS C codes are temporary codes established by CMS for use under the Hospital Outpatient Prospective Payment System (OPPS). Non-OPPS use of these codes for Medicare are not valid. The purpose of C codes is to provide hospitals with a list of codes and long descriptors for drugs, biologicals and devices eligible for transitional pass-through payments and for items classified in new technology ambulatory payment classifications (APCs) under OPPS. Effective July 1, 2014 three drugs and biologicals have been granted OPPS pass-through status.
