Coverage and Medical Necessity Criteria

(untitled)

Durable Medical Equipment (DME); related supplies, and orthotics are medically necessary when ALL of the following are met:

ALL of the following

The item(s) meets the plan's definition of medically necessary (refer to the federal, state, or contractual requirements).
Consistent with the state definition of DME and/or orthotic.
Ordered by a physician or ordered by a nurse practitioner, clinical nurse specialist, or physician assistant acting within the scope of practice under state law.
The item is not otherwise excluded from coverage per the member's benefit document and applicable federal, state, or contractual requirements.

Clinical coverage considerations

Clinical coverage considerations — clinical recommendations, guideline statements, and evidence summaries that inform coverage decisions for ventilators, BiPAP/NIV/CPAP, and related respiratory assist devices:

ALL of the following

Bi-level positive airway pressure (BiPAP) devices (HCPCS E0470, E0471) and other noninvasive ventilation (NIV) modalities are evaluated against available clinical evidence and guideline recommendations; coverage decisions reference InterQual and applicable Medicare/contractual criteria where indicated.
Refer to InterQual criteria for detailed scenario-specific medical necessity thresholds.
There is insufficient high‑quality evidence to support BiPAP as medically necessary for central sleep apnea (CSA) or obstructive sleep apnea (OSA) when adherent use is < 4 hours per sleep on at least 21–30 consecutive nights.
Insufficient evidence statement: adherence <4 hours/night over required days.
For patients with COPD and chronic hypercapnic respiratory failure, the evidence for home NIV/BiPAP shows mixed results; guideline bodies (ATS, NICE) suggest consideration of NIV for selected patients and recommend targeted PaCO2 normalization and screening for OSA prior to long‑term NIV initiation.
Clinical context: apply patient selection criteria from guidelines (eg, persistent hypercapnia, PaCO2 thresholds).
Several randomized trials and meta-analyses report reductions in PaCO2 with long‑term NIV in stable hypercapnic COPD, with variable effects on mortality and exacerbation rates; therefore, NIV may be reasonable for selected patients but is considered unproven when awake PaCO2 < 52 mmHg despite nocturnal elevations, per policy-specific thresholds.

Prior Authorization, Documentation, and Provider Requirements

Prior Authorization

Confirm benefit requirements and prior authorization

Confirm member benefits, federal/state rules, and prior authorization requirements before submitting requests. Coverage decisions must align with the member's specific plan, and where conflicts exist the federal, state, or contractual requirements govern.

Verify prior authorization requirements with UnitedHealthcare and applicable Medicaid/Medicare MAC rules before ordering or dispensing DME/RAD/ventilators.
Reference plan-specific benefit documents for exclusions, limits, and any age or diagnosis restrictions.

Denial Risk

Ventilator/BiPAP denial risks

Ventilators and BiPAP may be denied when used inappropriately (for example, when a lower level Respiratory Assist Device (RAD) is clinically indicated) or when clinical criteria are not met. Requests may also be denied if items do not meet the plan's or state definitions of DME or if replacement is requested within the Reasonable Useful Lifetime without justification.

Repair, Replacement, Upgrade and Clinical Necessity

Repair and accessory replacement

Repair coverage: Repairs and replacement of essential accessories (hoses, tubes, mouthpieces) for necessary DME are covered when required to make the item/device serviceable.

Repair/Replacement/Upgrade necessity

Medical necessity for repair/replacement/upgrade

Repair necessity: Repairs covered when necessary to make the device serviceable (includes essential accessories).

Replacement necessity: Replacement covered when device is irreparable and beyond its Reasonable Useful Lifetime (RUL); default RUL is 5 years unless federal/state/contractual requirements state otherwise.

Rental, Purchase, and Warranty Rules

Equipment category	Rental/Purchase rule	Notes
General DME (non‑PAP)	Capped rental	Reasonable Useful Lifetime (RUL) standard is 5 years; computation of RUL is based on date delivered to the member (CMS, 2021).
Orthotics, braces, other durable devices	Capped rental	Routine wear that renders equipment non‑functional while member still requires the item is covered; replacement tied to RUL and irreparability determination.
Supplies (non‑reusable)	Purchase preferred; rental rules not applicable	Supply items are consumable/disposable and RUL does not apply.

Situation	Rental rule	Provider/vendor responsibility
Equipment obtained as rental	Rented items follow rental provisions per benefit plan (vendors responsible for repairs/replacements/maintenance)	Vendors/manufacturers are responsible for repairs, replacements, and maintenance for rented equipment.
Purchased equipment covered under manufacturer warranty	Treated as purchased for benefit terms; vendor/manufacturer responsibility applies while under warranty	Vendors/manufacturers remain responsible for repairs/replacements/maintenance while item is under warranty.
Purchased equipment not under warranty	Subject to standard purchase/replacement rules including RUL considerations	Replacement requests require documentation showing item is irreparable or beyond the 5‑year RUL; coverage depends on benefit terms.

Device type	Rental vs Purchase	Plan/benefit note
PAP devices (CPAP/APAP/BiPAP/ASV) and accessories	Rental or purchase per member's benefit plan	Follow the member's federal/state/contractual benefit plan for whether PAP devices are rented or purchased; UnitedHealthcare reserves policy rights and benefit terms govern.
Humidifiers and disposable accessories (filters, masks, cushions)	Purchase (accessories/supplies); replacement per benefit plan	Supplies and disposable accessories are consumable; replacement and coverage determined by benefit plan terms and device usage documentation.
PAP device replacement	Determined per benefit plan (may require device data/documentation)	Replacement timing and coverage depend on benefit plan; provide device usage downloads or smart card data and documentation of clinical need when requested.

Replacement Intervals and Reasonable Useful Lifetime

General DME replacement interval

Standard replacement intervalGeneral DME replacement considered when beyond its Reasonable Useful Lifetime (RUL) of 5 years

Computation basisRUL computed from date equipment delivered to the member, not equipment age

ExceptionsExceptions and requests for earlier replacement are decided case‑by‑case per member benefit plan and medical necessity

General DME — every 5 years (Reasonable Useful Lifetime)

Reasonable Useful Lifetime (RUL) valueRUL standard for general DME is five (5) years

Computation ruleComputation of RUL is based on delivery date to the member (CMS, 2021)

Required Documentation for Coverage, Repair, and Replacement

Documentation Required

Document DME benefit, serviceability/irreparability, and RUL for repairs/replacements

Document that the member has an active DME benefit and that repair or replacement is necessary to render the equipment serviceable or that the item is irreparable; include evidence regarding RUL status when applicable.

Show member's DME benefit existence and relevant benefit language when requested.
Document whether the item is serviceable, irreparable, and whether it is beyond RUL.

Documentation Required

Physician statement and full new‑service documentation required for upgrades

Include a physician statement that documents the member's change in medical condition and explains why the upgrade is clinically necessary; submit the full documentation set required for a new equipment request.

Physician must describe the clinical change prompting the upgrade (e.g., new functional limitations).
Treat the request as a new service and include all standard initial documentation.

Background and Scope

Durable Medical Equipment (DME) refers to reusable, non‑implantable medical devices that serve a medical purpose in the member’s usual life settings and that can withstand repeated use. DME items are evaluated for medical necessity according to the plan definition and applicable federal, state, or contractual requirements; typical examples include respiratory assist devices (e.g., CPAP, BiPAP, ventilators), orthoses, and necessary accessories.

Key Definitions

Durable Medical Equipment (DME) definition

Core definitionDurable Medical Equipment (DME): Medical equipment that can withstand repeated use, is suitable for use in normal life settings, is not implantable, and is primarily used to serve a medical purpose

Additional characteristicsGenerally not useful in absence of a disability/illness/injury; can be reusable or removable; meets federal/state DME definitions

Place of useSuitable for use in any setting in which normal life activities take place

Reasonable Useful Lifetime (RUL) definition

RUL definitionReasonable Useful Lifetime (RUL): The standard amount of time considered reasonable for use of DME; standard set at five (5) years

Computation

Non-Covered Items and Exclusions

Fully implanted devices (for example, implants, pumps, stimulators, or monitors that are fully implanted) are explicitly not covered as DME. When such devices are covered, coverage is provided as part of the associated surgical or medical‑surgical service rather than under the DME benefit.

Replacement requests for DME that is still within its Reasonable Useful Lifetime (RUL) may be denied. Unless otherwise specified by the benefit or regulatory requirements, the policy uses a default RUL of 5 years. Providers should confirm member benefit terms and applicable federal/state/contractual rules before submitting replacement requests or exceptions.

Use of BiPAP devices in individuals with central sleep apnea (CSA) or obstructive sleep apnea (OSA) when device use is less than 4 hours during sleep on at least 21 to 30 consecutive days is considered not supported by sufficient evidence and therefore not covered as medically necessary in those circumstances.

On This Page

See policy criteria for the specific PaCO2 rule that renders BiPAP unproven for COPD.

Adaptive servo‑ventilation (ASV) increased harm in certain heart failure populations (eg, SERVE‑HF) and should be used in accordance with guideline contraindications and evidence‑based warnings.

Clinical safety consideration: ASV contraindication in selected HFrEF patients.

Guidelines recommend PAP therapy (CPAP/APAP) as first‑line for OSA in most adults; educational, behavioral, and telemonitoring interventions may improve adherence and should be offered when initiating PAP therapy.

Operational: provide education and adherence support per AASM/VA/DoD recommendations.

When coverage is considered for repair, replacement, or upgrade of respiratory assist devices, apply the general DME repair/replacement/upgrade criteria including Reasonable Useful Lifetime (RUL) and documentation of irreparability or change in medical condition.

Common adherence metric for PAPAdherence commonly assessed as device usage ≥4 hours/night on ≥70% of nights over a consecutive 30‑day period (used for coverage monitoring)

Alternate trial targetsSome NIV/ASV trials instructed device use for ≥5 hours/night or targeted 5–6 hours/day or night usage depending on protocol

Denial risk if device use does not meet InterQual/CMS clinical criteria for ventilatory support.
Replacement requests within the 5-year RUL may be denied unless exception criteria and documentation are provided.
Devices used solely to provide continuous positive airway pressure in situations where RAD is appropriate may be denied.

Prior Authorization

Benefit verification required

Verify benefits and coverage terms for the specific member and plan before applying policy criteria. Benefit verification must be documented in the patient record and prior authorization workflow.

Document the benefit check date, the representative or system used, and any plan-level exclusions or limits.
If federal or state rules supersede the policy, follow those requirements.

Documentation Required

Required documentation

Provide complete documentation to demonstrate medical necessity. Incomplete records may delay or result in denial of coverage.

Physician order and clinical notes describing diagnosis, symptoms, and functional limitations.
Provider attestation that the item meets the plan and state definitions of DME/orthotic.
Relevant testing, measurements, or objective data (e.g., arterial blood gases, polysomnography, pulmonary function tests) supporting the request.
For pediatric DME, documentation of growth accommodation and sizing needs.

Documentation Required

Upgrade documentation

Upgrades or changes in equipment due to a change in medical condition are treated as new services and require the same documentation as an initial request. The ordering physician must document the clinical change necessitating the upgrade.

Submit physician statement describing the change in functional status or clinical condition and why current equipment is insufficient.
Include comparisons to prior equipment, dates of prior delivery, and any trial/repair history.

Documentation Required

Device usage documentation

Use objective device data to document adherence and usage. Downloaded data or smart card reports should be submitted with continuation or upgrade requests to demonstrate therapeutic use.

Provide device usage reports showing hours/night and percentage of nights used (e.g., ≥4 hours on ≥70% of nights during a consecutive 30-day period where applicable).
Include manufacturer data cards, smart card downloads, or vendor-generated usage summaries.

Step Therapy

Respiratory device step criteria

Ensure the member meets required clinical step criteria before coverage of higher-level respiratory devices. Follow InterQual, CMS/MAC, and applicable guideline criteria to establish medical necessity prior to approval.

Document prior trials and failures or contraindications to first-line therapies (e.g., CPAP/APAP) when considering BiPAP or ventilator support.
Reference InterQual or CMS MAC criteria used to justify the higher-level device in the clinical record.

Note

Preferred sequencing of PAP modalities

Preferred sequencing: CPAP or APAP is recommended as first-line therapy for routine obstructive sleep apnea; CPAP/APAP is generally preferred over BiPAP unless clinical criteria indicate otherwise. Follow evidence-based guidelines when selecting PAP modality.

Document rationale for choosing BiPAP/ASV over CPAP/APAP, including trial data, intolerance, persistent symptoms, or objective physiologic indications.
When switching modalities, include adherence and efficacy data supporting the change.

RUL = 5 years (default)

Upgrade necessity: Upgrade covered when a documented change in the member's medical condition necessitates different equipment; upgrade requests are treated as new services and require the same documentation as a new request.

DME medical necessity criteria

Clinical indications and monitoring thresholds that inform medical necessity

Adherence threshold: Adherence is typically defined as device usage >= 4 hours per night on >= 70% of nights during a consecutive 30-day period within the first 3 months of use and device-recorded usage or smart‑card downloads may be used for documentation.>=4 hours/night on >=70% nights over 30 days

Initial therapy selection: CPAP or APAP are recommended as first‑line for routine OSA; BiPAP/ASV or long-term NIV are considered for select indications such as CSA, treatment‑emergent CSA on CPAP, hypercapnic respiratory failure, or CPAP intolerance per clinical guidelines.

RUL applicabilityRUL does not apply to supply items; federal/state/contractual requirements may supersede the default

PAP devices and accessories replacement

PAP replacement policyReplacement of PAP devices and accessories follows the member's benefit plan terms (rental vs purchase and replacement intervals governed by benefit)

Use of device dataDevice usage data and benefit rules may be used to support requests for replacement or continuation per plan terms

Plan verification requiredBefore applying policy, check federal, state, or contractual benefit plan coverage which may dictate replacement rules for PAP devices

Documentation Required

Supply smart‑card/download usage data when requested to prove adherence

Provide device usage downloads or smart card data when requested to document adherence for coverage continuation, replacement, or reassessment; trial definitions of adherence (e.g., ≥4 hours/night on 70% of nights over 30 days) may be used in assessments.

Submit smart card or embedded device reports showing average hours used over the specified period.
Use the documented usage period that corresponds to the coverage request (e.g., initial 90 days or the most recent 30‑day interval).

Computed from the date equipment is delivered to the member (CMS, 2021)

Policy implicationsReplacement is considered when equipment is beyond its RUL and irreparable; RUL may be superseded by federal/state/contractual requirements

RUL (alternate reference)

RUL restatementUnless otherwise stated by policy or federal/state/contractual requirements, DME has a RUL of 5 years

Replacement conditionReplacement of DME is for the same or similar equipment that is beyond its RUL and has become irreparable

Exceptions and requestsRequests for exceptions are based on member-specific benefit plan documents and medical necessity and are reviewed case‑by‑case

Hypopnea definition (for PAP evaluation)

Hypopnea duration and airflow reductionHypopnea: an event lasting at least 10 seconds with ≥30% reduction in airflow

Oxygen desaturation or arousalAssociated with at least a 3% oxygen desaturation from pre‑event baseline or associated arousal (AASM Scoring Manual, 2023)

ContextDefinition used for evaluation of PAP therapy and scoring of respiratory events

PAP (CPAP/APAP/BiPAP/ASV) — definition

PAP therapies includedPAP includes CPAP, APAP, BiPAP (bilevel PAP), and ASV (adaptive servo‑ventilation)

Guideline roleAASM recommends PAP vs no therapy for OSA and recommends CPAP or APAP for ongoing treatment; suggests CPAP/APAP over BiPAP for routine OSA

Clinical use casesBiPAP/ASV considered for CSA, treatment‑emergent CSA, hypercapnic respiratory failure, or CPAP intolerance as supported by clinical guidelines
