Durable medical equipment and other supplies

CHNW considers durable medical equipment (DME), orthotics, and prosthetics medically necessary when the applicable criteria are met. DME items have the following characteristics and should meet the following requirements:

  • Is prescribed by a physician
  • The order contains the physician’s signature, not a stamp
  • Can withstand repeated use
  • Is primarily and customarily used to serve a medical purpose
  • Is appropriate for use in the client’s place or residence
  • Meets the definition of DME

Exceptions: DME order can be signed by provider other than a physician in certain circumstances.

  • Medication administration or monitoring (such as blood glucose testing, continuous glucose monitoring, or insulin pumps), or home infusions
  • Respiratory supplies (such as CPAP mask or tubing)
  • Breast pumps
  • DME requests while member is in a facility (SNF, Inpatient Rehab, Long Term Acute Care or hospital). Signature will be required for members in custodial care, adult family home, or long-term care.

Special considerations

Rental: CHNW applies DME rental fees toward the eventual purchase of a device. (Some DME are for purchase only. Rules regarding rental versus purchase should be checked.)


  • The repair of any DME must meet relevant criteria for medical necessity, including prior authorization if required for similar new equipment.
  • Repair is considered only for client-owned equipment after expiration of warranty period. Any repair for DME must meet relevant criteria for medical necessity, including prior authorization if required for similar new equipment.
  • It is the provider’s responsibility to check warranty coverage before submitting a request for a DME repair. Warranty coverage will be reviewed, along with repair cost, at the time of assessment for prior authorization.
  • Repairs do not require a face-to-face evaluation with the physician but do require a physician signature on the order.


  • Replacement of any DME must meet relevant criteria for medical necessity, including prior authorization if required for similar new equipment.
  • Any requests for DME replacement must include documentation of a current (within 3 months) face-to-face evaluation by the treating physician and therapist, as applicable, showing medical need for the device by the member.
  • CHNW does not pay for the replacement of equipment, devices, or supplies, which have been sold, gifted, lost, broken, destroyed, or stolen as a result of the client’s carelessness, negligence, recklessness, deliberate intent, or misuse unless otherwise allowed under HCA program rules.
