CHAMPVA Certificate of Medical Necessity (CMN) for DME

CHAMPVA, the VA health program for eligible family members of veterans, wants a certificate of medical necessity (CMN) or a doctor's order with claims for several kinds of durable medical equipment. Clinicians meet it when ordering an insulin pump, oxygen, a barrier-free lift, a TENS unit, a power wheelchair or a wound VAC for a CHAMPVA beneficiary. The document travels with the claim and supports CHAMPVA's medical necessity review.

Who completes it

The ordering physician provides the CMN or order, stating the diagnosis and the medical need for the equipment. CHAMPVA publishes no branded CMN template, so the physician supplies the certificate in their own format with supporting medical documentation.

Submitting and payment

How to submit it
The CMN or order is attached to the CHAMPVA claim, either the provider's claim or VA Form 10-7959a when the beneficiary files for reimbursement. Claims must be filed within one year of the date of service, or within one year of discharge for inpatient care.
Who pays
The guidebook sets no fee for the certificate itself; when CHAMPVA is the primary payer it pays 75% of the allowed amount for covered DME after the deductible, and the beneficiary pays a 25% cost share.

Good to know

  • Oxygen claims need a CMN with flow rate, frequency and duration of use, expected length of need and delivery method. If the first CMN states a lifetime need, later bills need no new prescription.
  • For a barrier-free lift, the documentation should show a history of being unable to get out of bed and no caregiver to move the patient in or out of bed. Home modifications are not covered.
  • A wound VAC claim needs wound length, width and depth, the start date and expected duration. A power wheelchair or scooter also needs a seating evaluation and proof of use inside the home.
  • Insulin pumps are covered when the claim carries a CMN or doctor's order with a diagnosis of diabetes mellitus. TENS units and neurostimulators need a CMN or order containing the diagnosis.

Frequently asked questions

Does CHAMPVA have its own certificate of medical necessity form?

No. CHAMPVA does not publish a branded CMN template. Its guidebook defines a CMN as a document from the physician showing the medical necessity of the care or services prescribed as part of the treatment plan, so a signed certificate or doctor's order with the diagnosis and supporting documentation meets the requirement.

Which CHAMPVA equipment claims need a CMN?

The CHAMPVA Guidebook calls for a CMN with insulin pumps, oxygen and oxygen concentrators, and barrier-free lifts, and a CMN or doctor's order with TENS units, neurostimulators, motorized wheelchairs or scooters, and wound VACs. All durable medical equipment must be ordered by a physician before CHAMPVA will consider the claim.

Does a CHAMPVA oxygen CMN have to be renewed?

Not always. If the initial CMN shows an indefinite or lifetime need, CHAMPVA does not require a new prescription with each billing, as long as the diagnosis continues to support the need. That first CMN must state the flow rate, frequency and duration of use, estimated length of need and delivery method.
