Policy Education

Documentation does not support custom fit criteria.

Custom fitted orthotics are:

  • Devices that are prefabricated
  • They may or may not be supplied as a kit that requires some assembly. Assembly of the item and/or installation of add-on components and/or the use of some basic materials in preparation of the item does not change classification from OTS to custom fitted.
  • Classification as custom fitted requires substantial modification for fitting at the time of delivery to provide an individualized fit, i.e., the item must be trimmed, bent, molded (with or without heat), or otherwise modified resulting in alterations beyond minimal self-adjustment.
  • This fitting at delivery does require expertise of a certified orthotist or an individual who has equivalent specialized training in the provision of orthosis to fit the item to the individual beneficiary.

Substantial modification is defined as changes made to achieve an individualized fit during the final fitting at the time of delivery of the item that requires the expertise of a certified orthotist or an individual who has equivalent specialized training in the provision of orthotics such as a physician, treating practitioner, an occupational therapist, or physical therapist in compliance with all applicable Federal and State licensure and regulatory requirements. A certified orthotist is defined as an individual who is certified by the American Board for Certification in Orthotics and Prosthetics, Inc., or by the Board for Orthotist/Prosthetist Certification.

Documentation must be sufficiently detailed to include, but is not limited to, a detailed description of the modifications necessary at the time of fitting the orthosis to the beneficiary. This information must be available upon request.

Claims for custom fitted orthoses (L1810, L1832, L1843, L1845, L1847) will be denied as incorrect coding, with a statutory denial, when documentation shows that only minimal self-adjustment was required at the time of fitting (see Policy Specific Documentation Requirements section in the LCD).

Documentation was not received in response to the Additional Documentation Request (ADR) letter.

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 National Supplier Clearinghouse (NSC). The supplier standards can be found in 424 CFR Section 424.57(c).

Please remember, the documentation must be submitted within 45 days from the date on the ADR letter. Failure to provide the requested documentation within 45 days may result in a partial or complete denial of the claim. Submission information can be found on the ADR page of Noridian's website.

Documentation does not support coverage criteria.

For codes K0901, K0902, L1832, L1833, L1843, L1845 and L1850, knee instability must be documented by examination of the beneficiary and objective description of joint laxity (e.g., varus/valgus instability, anterior/posterior Drawer test).

Claims for K0901, K0902, L1832, L1833, L1843, L1845 or L1850 will be denied as not reasonable and necessary when the beneficiary does not meet the above criteria for coverage. For example, they will be denied if only pain or a subjective description of joint instability is documented.

Proof of Delivery (POD) is incomplete or missing elements.

POD documentation, as well as claims documentation, must be maintained in the supplier's files for 7 years (starting from the date of service).

Suppliers, their employees, or anyone else having a financial interest in the delivery of the item(s) are prohibited from signing and accepting an item on behalf of a beneficiary (i.e., acting as a designee on behalf of the beneficiary). The relationship of the designee to the beneficiary should be noted on the delivery slip obtained by the supplier (i.e., spouse, neighbor). The signature of the designee should be legible. If the signature of the designee is not legible, the supplier/shipping service should note the name of the designee on the delivery slip.

For the purpose of the delivery methods noted below, designee is defined as any person who can sign and accept the delivery of DMEPOS on behalf of the beneficiary.

The supplier should also have on file any documentation containing a description of the item delivered to the beneficiary to determine the accuracy of claims coding including, but not limited to, a voucher, invoice or statement in the supplier records. There must be a sufficient level of detail in the item description to definitively determine the appropriate HCPCS to be appended to the claim. The long description of the HCPCS code, may be used to provide a detailed description of the item being delivered.

Proof of delivery documentation must be available to the Medicare contractor on request. All services that do not have appropriate proof of delivery from the supplier will be denied and overpayments will be requested. Suppliers who consistently fail to provide documentation to support their services may be referred to the Office of Inspector General (OIG) or the National Supplier Clearinghouse for investigation and/or imposition of sanctions.

There are three methods of delivery. Regardless of the method of delivery, the contractor must be able to determine that the item(s) delivered are the same item(s) submitted for Medicare reimbursement and that the item(s) were received by a specific beneficiary:

  • Delivery directly to the beneficiary or authorized representative
  • Delivery via shipping or delivery service
  • Delivery of items to a nursing facility on behalf of the beneficiary

Method 1—Direct Delivery to the Beneficiary by the Supplier
Suppliers may deliver directly to the beneficiary or the designee. In this case, POD to a beneficiary must be a signed and dated delivery document. The POD document must include:

  • Beneficiary's name
  • Delivery address
  • Sufficiently detailed description to identify the item(s) being delivered (e.g., brand name, serial number, narrative description). The long description of the HCPCS code, may be used as a means to provide a detailed description of the item being delivered
  • Quantity delivered
  • Date delivered
  • Beneficiary (or designee) signature

The date delivered on the POD must be the date that the DMEPOS item was received by the beneficiary or designee. The date of delivery may be entered by the beneficiary, designee, or the supplier. When the supplier's delivery documents have both a supplier-entered date and a beneficiary or beneficiary's designee signature date on the POD document, the beneficiary (or designee) entered date is the date of service.

In instances where the supplies are delivered directly by the supplier, the date the beneficiary received the DMEPOS supply must be the date of service on the claim.

Method 2—Delivery via Shipping or Delivery Service Directly to a Beneficiary
If the supplier utilizes a shipping service or mail order, the POD documentation must be a complete record tracking the item(s) from the DMEPOS supplier to the beneficiary. An example of acceptable POD would include both the supplier's own detailed shipping invoice and the delivery service's tracking information. The supplier's record must be linked to the delivery service record by some clear method like the delivery service's package identification number or supplier's invoice number for the package sent to the beneficiary. The POD document must include:

  • Beneficiary's name
  • Delivery address
  • Delivery service's package identification number, supplier invoice number, or alternative method that links the supplier's delivery documents with the delivery service's records
  • Sufficiently detailed description to identify the item(s) being delivered (e.g., brand name, serial number, narrative description). The long description of the HCPCS code, may be used as a means to provide a detailed description of the item being delivered
  • Quantity delivered
  • Date delivered
  • Evidence of delivery

If a supplier utilizes a shipping service or mail order, suppliers must use the shipping date as the date of service on the claim.

Suppliers may also utilize a return postage-paid delivery invoice from the beneficiary or designee as a POD. This type of POD document must contain the information specified above.

Method 3—Delivery to Nursing Facility on Behalf of a Beneficiary
For items directly delivered by the supplier to a nursing facility or when a delivery service or mail order is used to deliver the item(s) to a nursing facility, the supplier must have:

  • Documentation demonstrating delivery of the item(s) to the facility by the supplier or delivery entity; and
  • Documentation from the nursing facility demonstrating receipt and/or usage of the item(s) by the beneficiary. The quantities delivered and used by the beneficiary must justify the quantity billed.
