Top Denial Reasons
- Documentation does not support coverage criteria.
- Advance Beneficiary Notice of Noncoverage (ABN) was not properly executed.
It is important for suppliers to be familiar with the documentation requirements and utilization parameters as outlined in the Knee Orthoses Local Coverage Determination (LCD) L33318, Policy Article A52465 [PDF] and Standard Documentation Requirements Article A55426.
Suppliers can also review specific policy resources for Knee Orthoses to find information related to proper documentation requirements including a physician letter, documentation checklists, and FAQs.
Suppliers can also review a specific policy Documentation Checklist for Knee Orthoses on the Noridian website.
Noridian provides education via supplier workshops, training opportunities, and presentations.
Information about probe/error validation reviews may be found in CMS Internet Only Manual (IOM), Publication 100-08, Medicare Program Integrity Manual, Chapter 3.
Documentation does not support coverage criteria.
For codes L1832, L1833, L1843, L1845, L1850, L1851, and L1852, 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 L1832, L1833, L1843, L1845, L1850, L1851, or L1852 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.
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 in order 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 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 below).
Advance Beneficiary Notice of Noncoverage (ABN) was not properly executed.
The ABN is a notice given to beneficiaries in Original Medicare to convey that Medicare is not likely to provide coverage in a specific case.
Since March 1, 2009, the ABN-G and ABN-L are no longer valid; and notifiers must use the revised Advance Beneficiary Notice of Noncoverage (CMS-R-131).
An ABN can remain effective for up to one year. If there is any change in care from what is described on the ABN within the 1-year period, a new ABN must be given. If during the course of treatment additional noncovered items or services are needed, the notifier must give the beneficiary another ABN. There is a one year limit for using a single ABN for an extended course of treatment. A new ABN is required when the specified treatment extends beyond one year.
The ABN must be verbally reviewed with the beneficiary or his/her representative and any questions raised during that review must be answered before it is signed. The ABN must be delivered far enough in advance that the beneficiary or representative has time to consider the options and make an informed choice. Employees or subcontractors of the notifier may deliver the ABN. ABNs are never required in emergency or urgent care situations. Once all blanks are completed and the form is signed, a copy is given to the beneficiary or representative. In all cases, the notifier must retain the original notice on file.
ABN delivery is considered to be effective when the notice is:
- Delivered by a suitable notifier to a capable recipient and comprehended by that recipient.
- Provided using the correct OMB approved notice with all required blanks completed.
