What is PDAC?

What exactly is PDAC?
PDAC is the pricing, coding analysis, and coding (PDAC), contractor to CMS. PDAC is responsible for (among other things) providing suppliers and manufacturers with assistance in determining which HCPCS code (Healthcare Common Procedure Coding System) should be used to describe DMEPOS items for the purpose of billing Medicare. In addition, the PDAC publishes a product classification list on its website that lists individual items to code categories. www.dmepdac.com

The process starts when a manufacturer submits a product to PDAC for coding verification. The PDAC will review the submitted material and product. A coding decision letter is sent to the manufacturer once a final code is determined for the product. The product and assigned code are then listed on the PDAC website.

While coding verification by the PDAC is a voluntary process for most products, some require coding verification review prior to claims submission (including all LSO, TLSO codes).


What does this mean for you, the DME supplier?
If a specific HCPCS code requires the product be reviewed by PDAC prior to claims submission, be sure to check the PDAC website to verify the product is listed with the code.

If PDAC coding verification is not required for a product or the manufacturer has not voluntarily submitted a product for coding verification, then the responsibility for coding decisions lies with the supplier.

As noted in the Local Coverage Determinations (LCD) and related CMS Policy Articles, claims for HCPCS codes will be denied if the products requiring coding verification review are not listed on the PDAC Product Classification List. Coding decisions are updated frequently. To avoid reimbursement recoupment and regulatory scrutiny, suppliers should refer to the Product Classification List often to ensure Durable Medical Equipment, Prosthetics, Orthotics, and Supplies (DMEPOS) items billed have been coded by the PDAC.
