Preauthorization is a process through which a request for provisional affirmation of coverage is submitted for review before a durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) item is furnished to a beneficiary and before a claim is submitted for payment. Preauthorization helps ensure that applicable coverage, payment, and coding rules are met before supplies are delivered.

Basics of Preauthorization for DME
Preauthorization is a process through which a request for provisional affirmation of coverage is submitted for review
before a durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) item is furnished to a beneficiary
and before a claim is submitted for payment. Preauthorization helps ensure that applicable coverage, payment, and
coding rules are met before supplies are delivered. Preauthorization may be needed before certain services can be
rendered or equipment supplied. Every insurance company has its unique guidelines for preauthorization for DME, still,
in this article, we shared the basics of preauthorization for general understanding purposes.
DME coverage is subject to the member’s benefit plan. Members may be responsible for paying a portion of the DME’s
cost in the form of a co-pay/coinsurance and/or deductible. Generally, the DME provider will notify the member when
co-pays/coinsurance and/or deductibles are due. You can submit a pre-authorization request in multiple ways. Most
insurance companies accept preauthorization requests for DME through online (provider portal); by fax; and by phone.
You will receive notification about pre-authorization requests by fax, via standard U.S. mail; and online (provider portal).
In the event there is an urgent request for equipment requiring preauthorization that needs to be ordered on a
weekend or on a holiday, most of the payers provide an emergency prior approval phone line.
Key Elements of Preauthorization for DME

(such as diagnosis, patient history, physical exam findings, progress notes, medication list, wound or incision/location).
2. Certificate of Medical Necessity
The requesting physician, not the DME supplier, is responsible for completing the certificate of medical necessity for all
prescribed DME items. The certificate of medical necessity may, however, be submitted by the requesting physician,
discharging facility, or DME supplier. A preauthorization request submitted without a certificate of medical necessity will
be denied for lack of information. Waiting to submit the preauthorization request until this is ready will save time and
reduce rework. Filling out the certificate of medical necessity form involves:
• Certifying the patient’s need. The treating physician must certify in writing the patient’s medical need for equipment
and attest the patient meets the criteria for medical devices and/or equipment.
• Issuing a plan of care. The treating physician must issue a plan of care for the patient that specifies: the type of
medical devices, equipment and/or services to be provided; and the nature and frequency of these services.
3. Written Prescription
• To initiate coverage of DME, the requesting physician must issue a prescription, or other written order on
personalized stationery, which includes:
• Member’s name and full address
• Provider’s signature (Signature stamps are not acceptable.)

• Date the provider signed the prescription or order
• Description of the items needed
• Start date of the order (if appropriate)
• Diagnosis
• A realistic estimate of the total length of time the equipment will be needed (in months or years)
• Electronic requests for DME preauthorization should be accompanied by a fax containing the written prescription and
any applicable certificate of medical necessity forms.
4. Reconsideration and Appeals Process
Cases that do not meet medical necessity may be reconsidered (have a peer-to-peer discussion) or appealed.
• Reconsideration process: A reconsideration is a post-denial, pre-appeal opportunity to provide additional clinical
information. Reconsideration must be requested within 2 to 3 weeks of the initial denial date. Peer-to-peer (P2P)
review requests can also be made verbally or in writing. P2P results in either a reversal or an upholding of the original
decision. The requestor and the member are notified via mail and fax.
• Appeals process: Insurance companies generally mention the appeals process in the denial letter. The provider can
submit appeals in the same ways (online, phone, fax) as they submitted a preauthorization request.
DME suppliers who submit bills to insurance companies must keep the provider’s original written order or prescription
in their files. Providers are advised to document the medical need for and utilization of DME items in the member’s
chart and to ensure information about the member’s medical condition is correct.

existence of medical need as indicated in the certificate of medical necessity form submitted with the preauthorization
request.
Preauthorization for Medicare
CMS recently announced the final rule for certain DMEPOS items. This final rule establishes a preauthorization process
for certain DMEPOS items through two steps. First, the rule establishes a Master List of DMEPOS items that are
frequently subject to unnecessary utilization and potentially subject to preauthorization based on certain criteria.
Second, it creates a ‘Required Prior Authorization List,’ a subset of items on Master List that are subject to
preauthorization. CMS announced that it would inform the public of those items on the Required Prior Authorization
List by publishing a notice in the Federal Register with 60 days’ notice before implementation.
