Prior Authorization Submissions

The easiest way to send a prior authorization request (PAR) to CGS is through the myCGS DME Web Portal. The Prior Authorization Smart Submission (PASS) application within myCGS allows you to take a step-by-step approach to sending your prior authorization. The PASS intuitive approach takes away extra work on your part by assuring you have reviewed everything when you send the documentation packet to CGS. Using the myCGS web portal is faster than simply faxing documents and you have knowledge CGS Medical Review received those pages.

If you are not sure if a specific HCPCS code is part of Medicare's Prior Authorization, use the Prior Authorization Lookup Tool

See the Prior Authorization for DMEPOS page for more information about submitting a prior authorization request.

Advance Determination of Medicare Coverage (ADMC)

Many of the PAR requests CGS receives are for wheelchair bases which are not part of prior authorization. For some of these bases, you are welcome to use ADMC for the HCPCS codes in the table below. ADMC is a voluntary program where suppliers send documentation via the myCGS web portal, esMD, fax or mail to be reviewed for medical necessity. Visit Advanced Determination of Medicare Coverage (ADMC) for more information.

HCPCS Code Type of Wheelchair Base
E1161 Manual adult size wheelchair, includes tilt in space
E1231 – E1234 Manual pediatric size wheelchair, includes tilt in space
K0005 Manual adult size wheelchair, ultra lightweight
K0008 Custom manual wheelchair/base
K0009 Manual adult size wheelchair, not otherwise classified
K0013 Custom Motorized/Power Wheelchair Base
K0890 – K0891 Power pediatric size wheelchair, Group 5 – Single or Multiple power options

CGS Connect

If you have other HCPCS codes where you would like clinical guidance, the CGS Medical Review department offers CGS Connect®. This voluntary program gives you an opportunity to ask for a clinical review of pre-claim documentation. CGS clinicians will evaluate documentation and give guidance before you supply the DMEPOS item to the Medicare beneficiary. The complete list of HCPCS and information on how to submit documentation for review is listed here.

As you can see, CGS has a number of resources available to help you with reviews of documentation before sending a claim to CGS. Be sure to review these programs, the HCPCS codes associated with each one, and the respective submission instructions.
