Payment of DMEPOS Items Based on Modifiers

The following modifiers were added to the HCPCS to identify supplies and equipment that may be covered under more than one DMEPOS benefit category:

• AU Item furnished in conjunction with a urological, ostomy, or tracheostomy supply;

• AV Item furnished in conjunction with a prosthetic device, prosthetic or orthotic; and

• AW Item furnished in conjunction with a surgical dressing.

Codes A4450 and A4452 are the only codes that have been identified at this time that would require use of all three of the above listed modifiers. Providers must report these modifiers on claims for items identified by codes A4450 and A4452 that are furnished on or after January 1, 2005. Modifier AU may also be applicable to code A4217. Providers must report modifier AU on claims for items identified by code A4217 that are furnished in conjunction with a urological, ostomy, or tracheostomy supply on or after January 1, 2005. Items identified by code A4217 that are furnished in conjunction with durable medical equipment are reported without a modifier. In the future, other codes may be identified as codes that must be submitted with these modifiers. Medicare contractors base payment for the codes A4217, A4450, and A4452 on the presence or absence of these modifiers.

Codes L8040 thru L8047 describe facial prostheses. Providers must report the following modifiers on claims for replacement of these items:

• KM Replacement of facial prosthesis including new impression/moulage; and

• KN Replacement of facial prosthesis using previous master model.

Providers must report these modifiers on claims for replacement of items identified by codes L8040 thru L8047 that are furnished on or after January 1, 2005. Medicare contractors base payment for the codes L8040 thru L8047 on the presence of these modifiers. These modifiers are only used when the prostheses is being replaced.

In accordance with section 302(c) of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA), the fee schedule update factors for 2004 thru 2008 for durable medical equipment (DME), other than items designated as class III devices by the Food and Drug Administration (FDA), are equal to 0 percent. The HCPCS codes for DME designated as class III devices by the FDA are identified on the DMEPOS fee schedule available on the above mentioned web site by presence of the KF modifier.

Elevating/stair climbing power wheelchairs are class III devices. Suppliers billing the DMERCs must submit claims for the base power wheelchair portion of this device using HCPCS code K0011 (programmable power wheelchair base) with modifier KF for claims submitted on or after April 1, 2004, with dates of service on or after January 1, 2004. For claims with dates of service on or after January 1, 2004, the elevation feature for this device should be billed using HCPCS code E2300 and the stair climbing feature for this device should be billed using HCPCS code A9270.

Regional home health intermediaries (RHHIs) will not be able to implement the KF modifier until January 1, 2005. Therefore, for claims with dates of service prior to January 1, 2005, HHAs must submit claims for the base power wheelchair portion of stair climbing wheelchairs with HCPCS code E1399. For claims with dates of service on or after January 1, 2005, HHAs must submit claims for the base power wheelchair portion of stair climbing wheelchairs with HCPCS code K0011 with modifier KF.

The fee schedule amounts for K0011 with and without the KF modifier appear on the fee schedule file referenced at www.cms.hhs.gov/providers/pufdownload/default.asp#dme. For claims with dates of service prior to January 1, 2005, RHHIs should pay claims for stair climbing wheelchair bases billed with code E1399 using the fee schedule amounts for K0011 with the KF modifier. All other claims for programmable power wheelchair bases should be paid using the fee schedule amounts for K0011 without the KF modifier.

Effective for claims with dates of service on or after January 1, 2005, HHAs must submit modifier KF along with the applicable HCPCS code for all DME items classified by the FDA as class III devices.
