In the case of collagen dressings coded A6021, A6022, A6023 and A6024, the predominate component must be collagen.

Effective for claims with dates of service on or after June 1, 2013, the only products which may be billed to Medicare using code A6021, A6022, A6023 and A6024 are those for which a written coding verification has been made by the PDAC contractor and are listed on the Product Classification List in the Durable Medical Equipment Coding System (DMECS) maintained on the PDAC web site,

The DME MACs will be updating the Surgical Dressing Local Coverage Determination and Policy Article with this information. All products currently listed on the Pricing, Data Analysis, and Coding (PDAC) contractor web site with HCPCS codes A6021, A6022, A6023 and A6024 will be end dated effective June 1, 2013, with the exception of the predicate product and a product recently reviewed by CMS’ Alpha Numeric Workgroup. Manufacturers will be required to submit a new coding verification application to the PDAC for review and assignment of the correct code for products currently coded as A6021, A6022, A6023 and A6024.

Products which have not received coding verification review from the PDAC must be billed with code A9270.
