HCPCS code L0174 (CERVICAL, COLLAR, SEMI-RIGID, THERMOPLASTIC FOAM, TWO PIECE WITH THORACIC EXTENTION) describes a cervical collar that is constructed of thermoplastic foam. It is a two piece system with posterior and anterior thoracic extensions. The thoracic extension must overlap the manubrium sternum anteriorly and to the thoracic vertebra T-1 posteriorly.

Products currently coded with L0174 which are listed on DMECS will be end dated as of August 31, 2011. A new coding application will need to be submitted for any product requesting this code. When the products are coded by the PDAC, those meeting the code specifications will be listed in the Product Classification Matrix on DMECS. Only those products listed may be billed using code L0174.

The PDAC coding verification application required for these products is the Orthotics application. This application is located on the PDAC website,
