Oscar Pressure-Reducing Support Surfaces (CG007) Form
Please answer all questions to determine coverage (0 of 4)
Pressure injuries (pressure ulcers, pressure sores) are areas of skin and tissue damage that form in regions
with unrelieved and/or increased pressure. Pressure injuries are often associated with prolonged
immobility, poor nutrition, and/or comorbid medical conditions. Pressure-reducing support surfaces
should be prescribed as a part of a comprehensive preventative or treatment plan to include proper skin
and tissue care, repositioning and mobilization, and nutrition interventions.
There are many pressure-reducing support surfaces used to care for and prevent the development of
pressure injuries, including specialized mattresses and mattress overlays. The primary function of these
support surfaces is to prevent focal areas of pressure and to better distribute the body surface over a
larger area. Pressure-reducing support surfaces are categorized into three groups based on their
features, such as the type of material and whether they are powered by electricity or not.
Definitions
“Pressure-Reducing Overlay” is a support surface designed to be placed directly on an existing support
surface (either an ordinary mattress or hospital bed).
“Pressure-Reducing Mattress” is a support surface designed to be placed directly on a hospital bed
frame.
1
“Integrated Bed System” is a support surface and bed frame are combined into a single unit, where the
integrated support surface is not capable of functioning separately.
“Non-Powered Support Surface” is a passive support surface not requiring external energy for
operation.
“Powered Support Surface” is a support surface which requires A/C or D/C electrical power for
operation.
“Alternating Pressure” is powered pressure redistribution via cyclic changes in loading/unloading.
“Low Air Loss” provides airflow to better manage the heat and humidity of the skin surface.
“Group 1 Support Surfaces'' are pressure-reducing mattress overlays or mattresses that can be placed
on top of a hospital bed, hospital bed frame or home mattress. They can be powered or non-powered.
Group 1 support surfaces include the following:
○ Non-powered or passive pressure-reducing mattress
■ Include foam, air, water, or gel mattress having ALL of the following:
1. Material height of 5 inches or greater
2. Durable, waterproof cover
3. Ability to be placed directly on hospital bed frame
4. For foam mattresses only: properties that provides adequate pressure reduction
(i.e., appropriate foam density)
○ Non-powered or passive pressure-reducing mattress overlays
■ Gel overlay: gel or gel-like layer height is 2 inches or greater
■ Air mattress overlay: interconnected air cells have height of 3 inches or greater when
inflated
■ Water mattress overlay: filled height is 3 inches or greater
■ Foam mattress overlay: must have ALL of the following
1.
If convoluted overlay (e.g., eggcrate): thickness 2 inches or greater plus peak
height 3 inches or greater; if non-convoluted: overall height of 3 inches or
greater
2. Foam with properties that provide adequate pressure reduction (i.e., appropriate
foam density)
3. Durable, waterproof cover
○ Powered pressure-reducing mattress overlay
■ Alternating pressure or low air loss overlay having ALL of the following:
1. Air pump or blowing that provides sequential inflation/deflation of air cells or a
low interface pressure throughout the overlay
2. A height of 2.5 inches or greater when inflated
2
3. Air chamber height, frequency of air cycling (for alternating pressure overlays),
proximity of the air chambers to one another, and air pressure provide adequate
member lift and pressure reduction
“Group 2 Support Surfaces” are pressure-reducing mattress overlays or mattresses (alternating pressure
or low air loss). They can be powered or advanced non-powered. These surfaces work by inflating tubes
or cells with air. Group 2 support surfaces include the following:
○ Powered pressure-reducing mattress or overlay
■ Alternating pressure or low air loss mattress/overlay having ALL of the following:
1. Air pump or blowing that provides sequential inflation/deflation of air cells or a
low interface pressure throughout the overlay
2.
Inflated height of 3.5 inches or greater (for overlay); inflated height of 5 inches or
greater (for mattress)
3. Air chamber height, frequency of air cycling (for alternating pressure overlays),
proximity of the air chambers to one another, and air pressure provide adequate
member lift and pressure reduction
4. Surface designed to reduce friction and shear
5. For mattress only: ability to be placed directly on hospital bed frame
○ Semi-electric hospital bed with powered pressure-reducing mattress:
■ Mattress must meet powered pressure-reducing mattress criteria above; and
■ The bed must function as an integrated bed-mattress system
○ Advanced non-powered passive pressure-reducing mattress or mattress overlay,which has ALL
the following:
■ Height and design of individual cells provide a substantial improvement in the pressure
reduction compared to Group 1
■ Height of the air chambers, proximity of the air chambers to one another, frequency of
air cycling (for alternating pressure overlays), and air pressure provide adequate member
lift, reduce pressure, and prevent bottoming out
■ Total height 3 inches or greater (for overlay); total height 5 inches or greater (for
mattress)
■ A surface designed to reduce friction/shearing forces
■ Substantiated evidence of the effectiveness of the specific pressure relieving surface for
treating conditions requiring a Group 2 support surface, as discussed in the “Clinical
Indications” section below
■ For mattress only: ability to be placed directly on hospital bed frame
“Group 3 Support Surfaces” are air-fluidized beds, which use warm air, under pressure, to set silicone
coated ceramic beads in motion to simulate the movement of fluid. When the patient is placed in bed,
body weight is evenly distributed over a large surface area, creating a floating sensation.

“Ordinary or Conventional (non-medical) Mattresses and Overlays” are typical furniture items that are
normally of use to people who do not have an illness or injury. Although they may be air-filled,
water-filled, gel-like or foam, ordinary mattresses and overlays are not primarily medical in nature.
“Pressure Injury Staging” is a method of classifying tissue damage resulting from a pressure-induced
wound. Stages are defined in this guideline as follows:
Stage
Description
Stage I
Localized area of non-blanching erythema with intact skin. May be more painful, a
different texture or a different temperature compared to adjacent tissue.
Stage II
Partial-thickness skin loss with exposed dermis and a moist pink or red wound bed.
May also present as an intact or ruptured serum-filled blister.
Stage III
Full-thickness skin loss. Subcutaneous fat and rolled wound edges may be visible,
but bone, tendon and muscle should NOT be exposed. Slough or eschar may be
present. Ulcer depth will vary by anatomical location.
Stage IV
Full-thickness skin and tissue loss with exposed bone, tendon, ligament, cartilage,
and/or muscle. Rolled wound edges, tunneling, and undermining are often present.
Slough or eschar may be present. Ulcer depth may vary by anatomical location. Can
extend into muscle and/or supporting structures.
Unstageable
Full-thickness skin/tissue loss with overlying slough or eschar that prevents full
evaluation of the depth and involvement of underlying structures.
“Deep-Tissue Pressure Injuries” are localized regions of intact or non-intact skin with non-blanching
deep red or purple discoloration. Most often due to damage of the underlying soft tissue due to
pressure or shearing forces.
Clinical Indications
Pressure-Reducing Support Surfaces - General Criteria
The Plan considers pressure-reducing support surfaces medically necessary when ALL of the following
criteria are met:
1. A signed and dated order (prescription) is submitted by the provider documenting the medical
necessity for the support surface; and
2. Medical records are submitted by the provider documenting the expected duration of the injury
or condition. Equipment is medically necessary only for the duration of the injury or condition,
and the Plan may determine whether a rental or purchase is appropriate based on the duration
of medical necessity; and

Group 2 Support Surface Treatment Duration
1. Group 2 support surfaces for members meeting the criteria for Group 2 Support Surfaces above
are generally medically necessary for up to 60 days from the date of the surgery.
2. Continued use of a Group 2 support surface is generally medically necessary until the injury is
healed. If healing fails to occur, documentation in the medical record should demonstrate
a. Continued need for a Group 2 support surface for wound management; and
b. Modifications in the care plan are being implemented to promote further healing.
Group 3 Support Surfaces
The Plan considers Group 3 support surfaces medically necessary when General Criteria is met AND ALL
of the criteria below are met:
1. The support surface is being used as part of a comprehensive, documented pressure injury
treatment plan; and
2. Member has a Stage III or IV pressure injury; and
3. Member is bedridden or chair bound as a result of severely limited mobility; and
4. Member would require institutionalization in the absence of an air-fluidized bed (i.e., placement
in a skilled nursing facility or hospitalization); and
5. The necessity for the air-fluidized bed is based on a comprehensive assessment and evaluation
of the member after conservative treatment has been attempted without success for at least 30
days. The evaluation generally must be performed within 1 week of initiation of therapy with the
air-fluidized bed. Documentation should generally specify that the following components have
been attempted as part of the conservative treatment plan:
a. Education of member and caregiver on prevention and management of pressure injuries;
and
b. Appropriate frequency of turning and repositioning; and
c. Appropriate management of moisture/incontinence; and
d. Wound care appropriate to Injury stage, including debridement if applicable; and
e. Use of a Group 2 support surface, when appropriate; and
f. Nutritional assessment and intervention consistent with overall care plan; and
g. Assessment by a nurse, physician, or other licensed health care practitioner at least
weekly
6. A trained, adult caregiver available to assist with activities of daily living, fluid balance, dry skin
care, repositioning, recognition and management of altered mental, dietary needs, prescribed
treatments and medications, and management and support of the air-fluidized bed system and
any potential problems with its maintenance and operation; and
7. A licensed physician directs the home treatment regimen, and re-evaluates and re-certifies the
medical necessity for the air-fluidized bed on a monthly basis; and
8. All other alternative equipment options have been appropriately considered and ruled out.
Group 3 Support Surface Treatment Duration

3. Continued use of a Group 3 support surface is generally considered medically necessary until the
injury is healed. If healing fails to occur, documentation in the medical record should
demonstrate:
a. Continued need for a Group 3 support surface for wound management, and
b. Modifications in the care plan are being implemented to promote further healing.
Repair/Replacement of Pressure-Reducing Support Surfaces
The Plan considers the repair or replacement of a mattress or overlay medically necessary when ALL of
the following criteria are met:
1. The treating physician must document that the item being repaired continues to be reasonable
and necessary; and
2. The treating physician or supplier must document that the repair is reasonable and necessary.
Experimental or Investigational / Not Medically Necessary
Ordinary or conventional (non-medical) mattresses and overlays are NOT considered medically necessary
by the Plan. They are not considered medically necessary as they are not within the scope of the
definition of Durable Medical Equipment (DME) because of the following reasons: They are not primarily
medical in nature, are not primarily used in the treatment of disease or injury, and are normally of use to
people who do not have an illness or injury. This applies to ordinary or conventional (non-medical)
mattresses and overlays regardless of their composition or design.
Group 3 Support Surfaces
Group 3 Support Surfaces are NOT considered medically necessary by the Plan in the following
circumstances:
1. Stage III or IV pressure injuries of the foot because the foot can be elevated to relieve pressure
without the use of a specialized air-fluidized bed; or
2. The member has coexisting pulmonary disease - lack of an adequate back support prevents
effective coughing and dry air inhalation may thicken pulmonary secretions; or
3. The member requires treatment with wet soaks or moist wound dressings that are not protected
by an impervious covering, such as plastic wrap or other occlusive material; or
4. Structural support of the home in which the bed is to be installed cannot safely support the
weight of the air-fluidized system (generally weighs 1600+ pounds); or
5. Home electrical system is unreliable or cannot support the required increase in electrical energy
consumption; or
6. Caregiver is unwilling or unable to provide the level of care required for the member to use of an
air-fluidized bed; or
7. Other known contraindications are present.
