Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Conservative treatment failed: Patient has exhausted conservative treatment without improvementfailed conservative therapy

Conservative treatment includes frequent repositioning (usually every 2 hours), pressure/shear reduction, infection management, nutrition optimization, debridement, maintenance of moist dressings with an occlusive covering, education, and moisture/incontinence management.

Alternative equipment ruled out: Physician has utilized and ruled out all other alternative equipment including, but not limited to, gel flotation pads, egg crate mattresses, and pressure pads and pumpsalternatives attempted/ruled out

Institutionalization need: Patient would require institutionalization in the absence of an air fluidized bedwould require institutionalization

Caregiver availability: Patient has a trained adult caregiver available to assist with activities of daily living, fluid balance, dry skin care, repositioning, recognition/management of altered mental status, dietary needs, prescribed treatments, and management/support of the air fluidized bed system (e.g., leakage)trained adult caregiver available

This policy covers use of an air fluidized bed only for the limited, specified indications. Specifically, the device is considered medically necessary for the treatment of pressure ulcers (decubitus ulcers, bedsores, pressure sores) and for the management of extensive burns in patients who are non‑ambulatory/bedridden. Use for any other condition or indication is outside the scope of coverage and is not medically necessary.

If the clinical indication does not match the specific uses described above (treatment of pressure ulcers or extensive burns in non‑ambulatory, bedridden patients), the air fluidized bed is considered not medically necessary. Providers should verify member benefits and any prior authorization requirements and ensure documentation clearly ties the request to an approved indication before submission.

Prior Authorization

Prior Authorization & Billing

Preauthorization may be required prior to provision of an air fluidized bed. Verify member benefits and obtain any required prior authorization before ordering or delivering the device.

Report with HCPCS code E0194

Step Therapy

Conservative Therapy Exhaustion

Patient must have exhausted conservative therapies and alternative support surfaces before an air fluidized bed is considered medically necessary. Conservative measures include frequent repositioning, pressure/shear reduction strategies, infection treatment, nutritional optimization, debridement, appropriate moist dressings with occlusive covering, caregiver and patient education, and management of moisture/incontinence. Alternatives such as gel flotation pads, egg crate mattresses, and pressure pads/pumps must have been tried and ruled out by the physician.

Documentation Required

Documentation and Benefit Verification

Medical record documentation supporting medical necessity must be available upon request. Always verify member benefits and any prior authorization requirements with the payer before ordering or billing.

Denial Risk

Not Covered Uses — Denial Risk

Use of an air fluidized bed for indications other than treatment of stage III/IV pressure ulcers in non-ambulatory bedridden patients or extensive burns in non-ambulatory bedridden patients is considered not medically necessary and may be denied.

DME-Specific Medical Necessity Criteria

DME-specific medical necessity criteria

Air fluidized bed is medically necessary when ALL criteria below are met:

Pressure ulcer stage: Stage III or Stage IV pressure ulcerStage III or IV

Mobility: Patient is non-ambulatory/bedridden or chair bound due to severely limited mobilitynon-ambulatory/bedridden

Wound dressing: Requires dry dressings or moist dressings protected by an impervious covering; does not require wet soaksdressing type

Conservative therapy: Conservative treatments attempted without improvementfailed conservative measures

Conservative measures include frequent repositioning (usually every 2 hours), pressure/shear reduction, infection treatment, nutritional optimization, debridement (including wet-to-dry gauze if used), maintenance of moist dressings with occlusive covering, education, and moisture/incontinence management.

Alternatives tried: All alternative equipment has been utilized and ruled out by the physician (examples: gel flotation pads, egg crate mattresses, pressure pads and pumps)alternatives tried/ruled out

Caregiver support: Trained adult caregiver available to manage bed system and patient care needscaregiver present

Documentation Requirements

Note

Provide documentation and obtain preauthorization

Provide supporting medical record documentation of medical necessity upon request and obtain preauthorization where required by the member's contract before furnishing the air fluidized bed.

Medical record documentation must be available upon request.
Preauthorization may be required; verify benefits and contract-specific requirements prior to provision.

Not Covered — Exclusions and Limitations

Not covered: Air fluidized beds for indications other than the treatment of pressure ulcers or extensive burns in non‑ambulatory, bedridden patients. Requests for other uses should be considered non‑covered and may be denied.

Background

Pressure ulcers (also called decubitus ulcers or bedsores) arise from prolonged pressure that compromises local blood flow and leads to tissue damage. In severely immobile patients, specialized support surfaces such as an air fluidized bed are intended to redistribute pressure and reduce shear forces to support healing of significant wounds and to assist in care of extensive burns. Because the clinical benefit is specific to these high‑risk, immobile populations, coverage is limited to the indications described in this policy.

Definitions

Air fluidized bed — definition and mechanism

DefinitionA support surface that circulates filtered air through ceramic beads under an air-permeable cover to create fluid-like movement and redistribute pressure

MechanismWarm pressurized air sets small ceramic beads in motion, simulating a fluid that evenly distributes body weight to reduce focal pressure

Indications statedMarketed to treat or prevent pressure ulcers and to treat extensive burns in immobile patients

Pressure ulcer staging — Stage I–IV definitions

Stage IObservable pressure-related alteration of intact skin; may show non-blanchable erythema, changes in temperature, tissue consistency, or sensation

Stage IIPartial-thickness skin loss involving epidermis, dermis, or both; presents as an abrasion, blister, or shallow crater

Stage IIIFull-thickness skin loss with damage to or necrosis of subcutaneous tissue that may extend down to, but not through, underlying fascia; presents as a deep crater

Stage IVFull-thickness skin loss with extensive destruction, tissue necrosis, or damage to muscle, bone, or supporting structures; may include undermining and sinus tracts
