Educational Resources

It is important for suppliers to be familiar with the documentation requirements and utilization parameters as outlined in the Power Mobility Devices Local Coverage Determination (LCD) L23598 and Policy Article A41127.

Suppliers can also review specific policy resources for Power Mobility Devices on the Noridian website. You will find information related to proper documentation requirements including a physician letter, documentation checklists, FAQs, and presentations used during Web-based workshops.

Noridian provides educational offerings by scheduling supplier workshops, training opportunities, and presentations.

Information about probe/error validation reviews may be found in CMS Publication 100-8, Program Integrity Manual (PIM), Chapter 3.

Policy Education

The beneficiary's medical records do not support that the beneficiary does not have sufficient upper extremity function to self propel an optimally configured manual wheelchair.

The beneficiary does not have sufficient upper extremity function to self-propel an optimally-configured manual wheelchair in the home to perform mobility related activities of daily living (MRADL) during a typical day.

  • Limitations of strength, endurance, range of motion, or coordination, presence of pain, or deformity or absence of one or both upper extremities are relevant to the assessment of upper extremity function.
  • An optimally-configured manual wheelchair is one with an appropriate wheelbase, device weight, seating options, and other appropriate non-powered accessories.

The documentation submitted contained no detailed product description or the detailed product description submitted was invalid.

Once the supplier has determined the specific power mobility device that is appropriate for the beneficiary based on the physician's 7-element order, the supplier must prepare a written document (termed a detailed product description).

This detailed product description (DPD) must comply with the requirements for a detailed written order as outlined in the Supplier Manual and CMS' Program Integrity Manual (Internet-Only Manual, Pub. 100-8), Chapter 5. Regardless of the form of the description, there must be sufficient detail to identify the item(s) in order to determine that the item(s) dispensed is properly coded.

The physician must sign and date the detailed product description and the supplier must receive it prior to delivery of the PWC or POV. A date stamp or equivalent must be used to document the supplier receipt date. The detailed product description must be available on request.

*ACA 6407 requires a written order prior to delivery (WOPD) for the HCPCS codes specified in the table contained in the Policy Specific Documentation Requirements Section below. The supplier must have received a complete WOPD that has been both signed and dated by the treating physician and meets the requirements for a DWO before dispensing the item. Refer the related Policy Article NON-MEDICAL NECESSITY COVERAGE AND PAYMENT RULES section for information about the statutory requirements associated with a WOPD.

The documentation submitted does not support the beneficiary's mobility limitation cannot be sufficiently and safely resolved by the use of an appropriately fitted cane or walker.

The patient's mobility limitation cannot be sufficiently and safely resolved by the use of an appropriately fitted cane or walker.

There was no documentation submitted.

Suppliers are in violation of Supplier Standard #28 when, upon request, they fail to provide requested documentation to a Medicare contractor. Medicare regulations (42 C.F.R §424.516[f]) stipulate that a supplier is required to maintain documentation for seven years from the date of service and, upon the request of CMS or a Medicare contractor, provide access to that documentation. Therefore, the consequences of failure to provide records may not only be a claim denial but also referral to the NSC.

Section 1833(e) of the Social Security Act precludes payment to any provider of services unless "there has been furnished such information as may be necessary in order to determine the amounts due to such provider". It is expected that the patient's medical records will reflect the need for the care provided. The patient's medical records include the physician's office records, hospital records, nursing home records, home health agency records, records from other healthcare professionals and test reports. This documentation must be available upon request. An order for each item billed must be signed and dated by the treating physician, kept on file by the supplier, and be available upon request.
