Durable medical equipment (DME) is defined as follows:
- Equipment must be able to withstand repeated use, and
- It must be primarily and customarily used to serve a medical purpose, and
- It should not be useful to a person in the absence of illness or injury, and
- The equipment should be appropriate for use in the home.
All requirements of the definition must be met before an item can be considered to be durable medical equipment.
Durability - An item is considered durable if it can withstand repeated use, i.e., the type of item which could normally be rented. Medical supplies of an expendable nature such as, incontinent pads, lambs wool pads, catheters, ace bandages, irrigating kits, sheets, and bags are not considered "durable" within the meaning of the definition.
Medical Purpose - Medical equipment is equipment which is primarily and customarily used for medical purposes and is not generally useful in the absence of illness or injury. In most instances, no development will be needed to determine whether a specific item of equipment is medical in nature. However, should it be necessary to determine whether an item constitutes medical equipment, information on the device and its use should be reviewed on an individual basis. This may include a review by the medical staff and/or specialists.
Equipment such as hospital beds, wheelchairs, iron lungs, respirators, intermittent positive pressure breathing machines, medical regulators, oxygen tents, crutches, canes, trapeze bars, walkers, inhalators, nebulizers, commodes, suction machines, and traction equipment presumptively constitute medical equipment. Hemodialysis equipment used in the home is considered DME and covered under the DME benefit.
Equipment which is primarily and customarily used for a nonmedical purpose may not be considered "medical" equipment for which payment can be made under the DME benefit. This applies even though the item has some remote medically related use. For example, in the case of a cardiac patient, an air conditioner might possibly be used to lower room temperature to reduce fluid loss in the patient and to restore an environment conducive to maintenance of the proper fluid balance. Nevertheless, because the primary and customary use of an air conditioner is a nonmedical one, the air conditioner cannot be deemed to be medical equipment for which payment can be made.
Other devices and equipment used for environmental control or to enhance the environmental setting are not considered covered DME. These include, for example, room heaters, humidifiers, dehumidifiers, and electric air cleaners. Equipment which basically serves comfort or convenience functions or is primarily for the convenience of a person caring for the patient, such as elevators, stairway elevators, and posture chairs, does not constitute medical equipment. Similarly, physical fitness equipment, e.g., an exercycle; first-aid or precautionary-type equipment, e.g., preset portable oxygen units; self-help devices; and training equipment, e.g., speech teaching machines and braille training texts, are considered nonmedical in nature.
Necessary and Reasonable — Although an item may be classified as DME, it may not be covered in every instance. Coverage in a particular case is subject to the requirement that the equipment be necessary and reasonable for treatment of an illness or injury, or to improve the functioning of a malformed body member.
Equipment is necessary when it can be expected to make a meaningful contribution to the treatment of the patient's illness or injury or to the improvement of his malformed body member. In most cases, the physician's prescription for the equipment and other available medical information will be sufficient to establish that the equipment serves this purpose.
Payment will not be made for equipment which cannot reasonably be expected to perform a therapeutic function in an individual case and only partial payment will be made when the type of equipment furnished substantially exceeds that required for the treatment of the illness or injury involved.
A request for equipment containing features of an aesthetic nature or features of a medical nature which are not required by the patient's condition or where there exists a reasonably feasible and medically appropriate alternative pattern of care which is less costly than the equipment furnished, payment will be based on the reasonable charge for the equipment or alternative treatment which meets the patient's medical needs.
