Medicare Advantage Policy

Title:Home Oxygen Therapy
Policy #:MA05.017b

This policy is applicable to the Company’s Medicare Advantage products only. Policies that are applicable to the Company’s commercial products are accessible via a separate commercial policy database.


The Company makes decisions on coverage based on the Centers for Medicare and Medicaid Services (CMS) regulations and guidance, benefit plan documents and contracts, and the member’s medical history and condition. If CMS does not have a position addressing a service, the Company makes decisions based on Company Policy Bulletins. Benefits may vary based on contract, and individual member benefits must be verified. The Company determines medical necessity only if the benefit exists and no contract exclusions are applicable. Although the Medicare Advantage Policy Bulletin is consistent with Medicare’s regulations and guidance, the Company’s payment methodology may differ from Medicare.

When services can be administered in various settings, the Company reserves the right to reimburse only those services that are furnished in the most appropriate and cost-effective setting that is appropriate to the member’s medical needs and condition. This decision is based on the member’s current medical condition and any required monitoring or additional services that may coincide with the delivery of this service.


This Policy Bulletin document describes the status of CMS coverage, medical terminology, and/or benefit plan documents and contracts at the time the document was developed. This Policy Bulletin will be reviewed regularly and be updated as Medicare changes their regulations and guidance, scientific and medical literature becomes available, and/or the benefit plan documents and/or contracts are changed.



Policy

Coverage is subject to the terms, conditions, and limitations of the member's Evidence of Coverage.

The Company reserves the right to reimburse only those services that are furnished in the most appropriate and cost-effective setting that is appropriate to the member’s medical needs and condition.

*For all the sleep oximetry criteria described above, the 5 minutes do not have to be continuous.

Group II Certification and Recertification Requirements

The following requirements must be met.

Certification requirements to establish initial medical need:

Initial Certification Requirements
Testing Requirements
Professional Provider Visit Requirements
With the first claim for home
Oxygen
  • Initial coverage for individuals meeting Group II criteria is limited to 3 months or the professional provider specified length of need, whichever is shorter.
The blood gas study or pulse oximetry study must be the most recent study obtained within 30 days prior to the Initial Date.The individual must be seen and evaluated by the treating professional provider within 30 days prior to the date of Initial Certification.


Recertification requirements to confirm medical need still exists:

Recertification Requirements
Testing Requirements
Professional Provider Visit Requirements
3 months after Initial
Certification; that is, the fourth month’s claim.
The most recent blood gas study or pulse oximetry study performed between the 61st and 90th day following initial certification must be reported on the recertification.The individual must be seen and re-evaluated by the treating professional provider within 90 days prior to the date of the recertification.

Recertification requests for Replacement Equipment
  • Use the most recent qualifying arterial oxygen saturation or pulse oximetry study. This test does not have to be within 30 days prior to the initial date. It can be the test reported on the most recent certification.
  • There is no requirement for a professional provider visit related to the certification for replacement of equipment.

When both arterial blood gas (ABG) and pulse oximetry studies have been performed on the same day under the same conditions (i.e., at rest/awake, during exercise, during sleep) the ABG result will be used to determine if the coverage criteria were met. If an ABG test at rest/awake is nonqualifying, but an exercise or sleep oximetry study on the same day is qualifying, the oximetry study will determine the coverage.

PORTABLE OXYGEN
Portable oxygen systems are considered medically necessary and, therefore, covered when the individual is mobile within the home and the qualifying blood gas study or pulse oximetry study was performed while at rest (awake) or during exercise. If the only qualifying blood gas study or pulse oximetry study was performed during sleep, portable oxygen is considered not medically necessary and, therefore, not covered.

NOT MEDICALLY NECESSARY

GROUP III CRITERIA
Home oxygen therapy is considered not medically necessary and, therefore, not covered when either of the following Group III criteria are present:
  • The individual demonstrates arterial PO2 levels at or above 60 mmHg.
  • The individual demonstrates arterial blood oxygen saturations or pulse oximetry study at or above 90 percent.

Home oxygen therapy is considered not medically necessary and, therefore, not covered in the treatment of the following conditions:
  • Angina pectoris in the absence of hypoxemia. This condition is generally not the result of a low oxygen level in the blood, and there are other preferred treatments.
  • Dyspnea without cor pulmonale or evidence of hypoxemia.
  • Terminal illnesses that do not affect the respiratory system.
  • Severe peripheral vascular disease resulting in clinically evident desaturation in one or more extremities but in the absence of systemic hypoxemia. There is no evidence that increased PO2 will improve the oxygenation of tissues with impaired circulation.

If all of the coverage conditions specified above for Group I or Group II criteria are not met, home oxygen therapy is considered not medically necessary and, therefore, not covered.

EMERGENCY OR STAND-BY OXYGEN
Emergency or stand-by oxygen for individuals who are not currently meeting the requirements for oxygen is considered not medically necessary, and, therefore, not covered.

PRESCRIPTION RENEWAL

A revised prescription for home oxygen therapy is required in any of the following situations:

Revised Certification Requirements
Testing Requirements
Professional Provider Visit Requirements
1. When the prescribed maximum flow rate changes from one of the following categories to another:
    1. Less than 1 Liter per Minute (LPM),
    2. 1-4 LPM, or
    3. Greater than 4 LPM.

2. When the length of need expires, if the professional provider specified less than lifetime length of need on most recent letter of necessity.
The blood gas study or pulse oximetry study must be the
most recent study obtained within
30 days prior to the revised date.
  • If the change is from category (a) or (b) to category (c), a repeat blood gas study or pulse oximetry study with the individual on 4 LPM must be performed
There is no requirement for a professional provider visit.
3. When a portable oxygen
system is added subsequent to Initial Certification of a stationary system.
There is no requirement for a
repeat blood gas study or pulse oximetry study unless

study or pulse oximetry study must be performed while
the individual is at rest (awake) or during exercise within 30 days prior to the Revised Date.
There is no requirement for a professional provider visit.
4. When a stationary system is
added subsequent to Initial
Certification of a portable system.
No blood gas study or pulse oximetry study is required.There is no requirement for a professional provider visit.
5. When there is a new treating
professional provider, but the oxygen order is the same; or

6. If there is a new DME provider, and the new DME provider does not have the prior prescription.
No blood gas study or pulse oximetry study is required.There is no requirement for a professional provider visit.

OXYGEN ACCESSORIES AND SUPPLIES

The Non-invasive Open ventilation system (NIOV) (E1352), by Breath Technologies, Inc. provides positive pressure inspiratory support for individuals using oxygen. This product consists of (control unit, flow regulator, connecting hose and nasal interface (pillows) (A9900). Per the manufacturer, the NIOV is an item that's effective only when used in conjunction with oxygen. An item that is effective only when used in conjunction with oxygen; is therefore, classified as an accessory to oxygen equipment.

All home oxygen therapy equipment from contracted providers is rented rather than purchased. Oxygen supplies and accessories (e.g., nasal cannula, tubing, face mask, oxygen conserving devices) are included in the rental reimbursement and are therefore, not eligible for separate reimbursement.

TESTING SPECIFICATIONS

Overnight oximetry refers to stand-alone pulse oximetry continuously recorded overnight. It does not include oximetry results done as part of other overnight testing for sleep apnea such as polysomnography (PSG) or home sleep testing.

For home overnight oximetry studies, the oximetry provided to the individual must be tamper proof, have the capability to download data, allow documentation of the duration of oxygen desaturation below a specified value and be under the direction of Diagnostic Testing Facility.
For individuals with obstructive sleep apnea (OSA), this means that the OSA must be sufficiently treated such that the underlying severe lung disease is unmasked. This must be demonstrated before oxygen saturation results obtained during polysomnography are considered qualifying for oxygen therapy. A qualifying oxygen saturation study may only occur during a titration polysomnographic study (either split night or stand-alone) if all of the following criteria are met:
  1. The titration is conducted over a minimum of two (2) hours; and
  2. During titration:
    1. The AHI/RDI is reduced to less than or equal to an average of ten (10) events per hour; or
    2. If the initial AHI/RDI was less than an average of ten (10) events per hour, the titration demonstrates further reduction in the AHI/RDI; and
  3. Nocturnal oximetry conducted for the purpose for oxygen reimbursement qualification may only be performed after optimal positive airway pressure (PAP) settings have been determined and the individual is using the PAP device at those settings; and
  4. The nocturnal oximetry conducted during the PSG demonstrates an oxygen saturation ≤ 88% for 5 minutes total (which need not be continuous)

When oxygen is covered based on an oxygen study obtained during exercise, there must be documentation of three oxygen studies in the individual's medical record (i.e., testing at rest without oxygen, testing during exercise without oxygen, testing during exercise with oxygen applied [to demonstrate the improvement of the hypoxemia]). All three tests must be performed within the same testing session. Only the qualifying test value (i.e., testing during exercise without oxygen) is reported on the Certificate of Medical Necessity. The other results do not have to be routinely submitted but must be available on request.

The qualifying blood gas study or pulse oximetry test may be performed while the individual is on oxygen as long as the reported blood gas or pulse oximetry study values meet the Group I or Group II criteria.

CLINICAL TRIALS

Home oxygen therapy for individuals who have an arterial PO2 ranging from 56 mmHg to 65 mmHg, or an oxygen saturation at or above 89 percent, is eligible for reimbursement consideration by Medicare provided that the individual is enrolled in a clinical trial approved by the Centers for Medicare and Medicaid Services (CMS) and sponsored by the National Heart, Lung, and Blood Institute (NHLBI).

Claims for individuals enrolled in the above clinical trail should be submitted to Medicare.

CLUSTER HEADACHES

Home oxygen therapy, for individuals diagnosed with cluster headaches, is eligible for reimbursement consideration by Medicare provided that the individual is enrolled in a clinical trial approved by the Centers for Medicare and Medicaid Services (CMS).

Claims for home oxygen therapy, when used for individuals diagnosed with cluster headaches, in a Medicare approved clinical trial, should be submitted to Medicare.

FACE-TO-FACE REQUIREMENTS

As a condition for payment, a professional provider must have a face-to-face examination with the individual for whom the item is ordered that meets all of the following requirements:
  • The treating professional provider must have an in-person examination with the individual within the six (6) months prior to the date of the written order prior to delivery.
  • This examination must document that the individual was evaluated and/or treated for a condition that supports the need for the item(s) of DME ordered.

A new face-to-face examination is required each time a new prescription for one of the specified items is ordered. A new prescription is required:
  • For all claims for purchases or initial rentals
  • When there is a change in the prescription for the accessory, supply, drug, etc.
  • If periodic prescription renewal required per medical policy
  • When an item is replaced
  • When there is a change in the supplier
  • When required by state law

In this policy the specified items are:

REQUIRED DOCUMENTATION

The Company may conduct reviews and audits of services to our members regardless of the participation status of the provider. Medical record documentation must reflect the medical necessity of the care and services provided. These medical records may include, but are not limited to: records from the professional provider's office, hospital, nursing home, home health agencies, therapies, and test reports.

PRESCRIPTION (ORDER) REQUIREMENTS
Before submitting a claim to the Company, the supplier must have on file a timely, appropriate and complete order for each item billed that is signed and dated by the professional provider who is treating the member. Requesting a provider to sign a retrospective order at the time of an audit or after an audit for submission as an original order, reorder, or updated order will not satisfy the requirement to maintain a timely professional provider order on file.

PROOF OF DELIVERY
Medical record documentation must include a contemporaneously-prepared delivery confirmation or member’s receipt of supplies and equipment. The medical record documentation must include a copy of delivery confirmation if delivered by a commercial carrier and a signed copy of delivery confirmation by member/caregiver if delivered by the DME supplier/provider. All documentation is to prepared contemporaneous with delivery and be available to the Company upon request.

CONSUMABLE SUPPLIES
The durable medical equipment (DME) supplier must monitor the quantity of accessories and supplies an individual is actually using. Contacting the individual regarding replenishment of supplies should not be done earlier than approximately seven days prior to the delivery/shipping date. Dated documentation of this contact with the individual is required in the individual’s medical record. Delivery of the supplies should not be done earlier than approximately five days before the individual would exhaust their on-hand supply.

Documentation of a face-to-face encounter between the treating professional provider and the individual meeting the above requirements, including an assessment of the individual’s clinical condition supporting the need for the prescribed DME item(s), must be provided to and kept on file by the DME supplier.

If required documentation is not available on file to support a claim at the time of an audit or record request, the durable medical equipment (DME) supplier may be required to reimburse the Company for overpayments.
Policy Guidelines

This policy is consistent with Medicare's coverage criteria. The Company's payment methodology may differ from Medicare.

BENEFIT APPLICATION

Subject to the terms and conditions of the applicable Evidence of Coverage, home oxygen is covered under the medical benefits of the Company’s Medicare Advantage products when the medical necessity criteria listed in this medical policy are met.

However, services that are identified in this policy as not medically necessary or not eligible for separate reimbursement, are not eligible for coverage or reimbursement by the Company.

Description

Home oxygen therapy is most commonly used to treat chronic, stable medical conditions that cause significant hypoxemia, such as severe lung disease (e.g., chronic obstructive pulmonary disease [COPD], interstitial fibrosis, cystic fibrosis, pulmonary neoplasm), pulmonary hypertension, and congestive heart failure related to cor pulmonale. Appropriate evidence of significant hypoxemia includes arterial blood gas studies, pulse oximetry, and certain clinical signs such as elevated pulmonary artery pressure, dependent edema, and polycythemia vera.

Home oxygen therapy may be delivered via nasal cannula, face mask, or transtracheal catheter. Supply sources include a stationary or portable compressed gas tank, stationary or portable liquid oxygen tank, or stationary oxygen concentrator. Any item that is effective only when used in conjunction with oxygen; is therefore, classified as an accessory to oxygen equipment.
