Evidence of Medical Necessity
5.11 - Evidence of Medical Necessity
(Rev. 10538; Issued: 12-30-20; Effective: 01-01-20; Implementation: 12-29-20)
If replacement supplies are needed for the therapeutic use of purchased DMEPOS, the
treating practitioner must specify on the standard written order, or on the CMN, the type
of supplies needed, in such a manner that the supplier may calculate the necessary
disbursement and assess the continued need for refill with the beneficiary. DME
MACs, UPICs, and other contractors evaluate supply utilization information as part of
their medical necessity and coverage determinations for DMEPOS.
Absent a State law to the contrary or a supply utilization problem, the standard written
order or CMN submitted for the DMEPOS may also serve as medical evidence for supply
replacement claims. However, when a standard written order for DMEPOS is renewed or
revised, supply utilization information must be specified or updated by the treating
practitioner on the CMN. DME MACs, UPICs, and other contractors assess the
continuing medical necessity.
The DME MACs, UPICs, and other contractors must establish procedures for monitoring
the utilization of replacement supplies. Suppliers must have documentation to support the
medical necessity of changes in the equipment, device, or supply utilization requirements.
Absent such notification, DME MACs, UPICs, and other contractors do not allow claims
for unexplained increases in supply utilization above the usage level they previously
determined as medically necessary. Suppliers shall make this information available to
the DME MACs, UPICs, and other contractors on request.
If necessary or appropriate for a medical necessity determination, the DME MAC, UPIC,
or other contractor must ask the supplier to obtain documentation from the treating
practitioner, establishing the severity of the patient's condition and the immediate and
long term need for the equipment and the therapeutic benefits the patient is expected to
realize from its use. A claim of therapeutic effectiveness or benefit based on speculation
or theory alone cannot be accepted. When restoration of function is cited as a reason for
use of DMEPOS, the exact nature of the deformity or medical problem should be clear
from the medical evidence submitted. Also, the manner in which the equipment or device
will restore or improve the bodily function should be explained by the treating
practitioner.
If the DME MAC, UPIC, or other contractor is unsuccessful in obtaining medical
information from the supplier for non-assigned claims, it gives the beneficiary the
opportunity to obtain the desired information from the supplier. If, after obtaining the
requested information, a question of medical necessity remains, the DME MAC, UPIC,
or other contractor must resolve the issue.
