Coverage Criteria for Home Oxygen Therapy

Initial Request Criteria

Coverage supported when documentation contains required test results and, where applicable, affirmative supporting clinical findings for borderline results.

Initial request completion: Member is aged 5 or older; provider completed Sections A and C with testing method, date, and results; oxygen equipment order completed with type, LPM, and frequency; ordering clinician signature present.

Supplier must not complete Sections B–E; use Under 5 CMN if under age 5

Sufficient physiologic criteria: At least one qualifying oxygen measurement demonstrating hypoxemia (documented arterial PO2 or oxygen saturation per testing method: rest, exercise, or sleep).See thresholds module for PO2/O2 sat values

If all test results are PO2 56-59 mm Hg or O2 sat ≥89%, additional criteria below apply

Borderline result support: When all test results are arterial PO2 56-59 mm Hg or arterial O2 sat ≥89%, at least one of the following must be present: dependent edema suggesting congestive heart failure; documented pulmonary hypertension or cor pulmonale by measurement of pulmonary artery pressure, gated blood pool scan, echocardiogram, or 'P' pulmonale on EKG; erythrocythemia with hematocrit >56%; OR a medical condition with distinct physiologic, cognitive, or functional symptoms expected to improve with oxygen therapy.PO2 56-59 mm Hg or O2 sat ≥89%; Hct >56%

Form includes checkboxes for these conditions and a question about symptomatic improvement

This form is intended for initial oxygen equipment requests for members aged 5 or older. Do not use this form for members under age 5; instead, complete the separate Under 5 CMN form as directed in Section C.

When all recorded test results are in the borderline range (arterial PO2 of 56–59 mm Hg or arterial O2 saturation of ≥ 89%), the form requires documentation of at least one supporting finding. The provider must indicate whether the member has: dependent edema suggesting congestive heart failure; pulmonary hypertension or cor pulmonale confirmed by objective testing; or erythrocythemia with hematocrit > 56%. If none of these are present, the form asks whether the member has a medical condition with distinct physiologic, cognitive, or functional symptoms expected to improve with oxygen therapy; absence of any supportive condition or symptomatic improvement means coverage is not supported per the form logic.

Key Numerical Thresholds and Form Fields

inv-04: Borderline PO2/O2 sat — arterial PO2 56-59 mm Hg or arterial O2 sat ≥ 89%

Borderline PO2/O2 saturationArterial PO2 56-59 mm Hg or arterial O2 saturation ≥ 89%

When to trigger follow-up questionsIf all entered test results meet the above borderline values, provider must answer additional clinical questions on the form

Follow-up areas queriedDependent edema suggesting CHF; pulmonary hypertension/cor pulmonale; erythrocythemia (hematocrit criteria)

inv-05: Erythrocythemia hematocrit supportive criterion — > 56%

Erythrocythemia hematocrit threshold> 56%

Where documentedListed as a follow-up supportive criterion on the form when test results are borderline

Provider Responsibilities, Documentation, and Notices

Documentation Required

Initial Request Documentation and Signatures

Complete the Initial Request Documentation and Signatures for members aged 5 years or older using the CMN form. The form must include the testing method(s) used (rest, exercise, sleep), date(s) of test, test results (arterial PO2 in mm Hg and/or O2 saturation in %), the oxygen equipment ordered (type and LPM), frequency of use, and required provider/prescriber signatures with dates. If member is under 5, use the Under 5 CMN form.

Member and supplier identification (Member name, Medicaid ID; Supplier name, Supplier Medicaid ID)
Prescriber identification (Prescriber name, Prescriber Medicaid ID or NPI)
Date of visit addressing oxygen and requested start date
Estimated length of need (months; 99 = lifetime)
Diagnosis codes and descriptions, DOB, sex, height, weight
Method of testing: rest, exercise, and/or sleep (check all that apply)
Date of test(s) and specific results: arterial PO2 (mm Hg) and/or O2 saturation (%) — record all measured values
If results are borderline (PO2 56–59 mm Hg or O2 sat ≥ 89%), document answers to edema, pulmonary hypertension/cor pulmonale, and erythrocythemia questions, and whether the member has symptoms likely to improve with oxygen therapy

Clinical Background and Test Types Collected

The form collects physiologic measurements used to document need for supplemental oxygen, including arterial PO2 (mm Hg) or oxygen saturation (%) taken at rest, during exercise, and/or during sleep. Section C instructs the ordering clinician to record the testing method, test dates, and the numerical results; if results fall into the borderline range the form requires answers to additional clinical questions and the ordering clinician's certification that the information provided supports medical necessity.

Terminology and Clinical Definitions

inv-12: Borderline hypoxemia definition — arterial PO2 of 56-59 mm Hg or arterial O2 saturation ≥89%, triggers additional clinical questions about CHF, pulmonary hypertension, etc.

Borderline hypoxemia thresholdArterial PO2 of 56-59 mm Hg or arterial O2 saturation ≥ 89%

Follow-up clinical questionsDependent edema suggesting congestive heart failure; pulmonary hypertension or cor pulmonale confirmed by objective testing; erythrocythemia (hematocrit >56%)

Testing contextApplies when all entered test results on the form meet the borderline threshold

Step Therapy

No Step Therapy Specified

The completed form does not impose any step therapy requirements. Providers are not required to trial alternative therapies or devices prior to this request under this form.

Documentation Required

Required Form Fields and Supporting Test Data

The CMN must include all of the following supporting test data and form fields to be complete: member and prescriber identification, date of visit addressing oxygen, requested start date, estimated length of need, diagnosis codes, DOB/sex/height/weight; method of testing (rest/exercise/sleep), date(s) of test, and explicit test results (arterial PO2 in mm Hg and/or O2 saturation in %). For arterial PO2 values of 56–59 mm Hg or O2 saturation ≥ 89%, the form must document dependent edema, pulmonary hypertension/cor pulmonale, and erythrocythemia status (hematocrit > 56%), and whether there is a medical condition with physiologic/cognitive/functional symptoms expected to improve with oxygen. Also include oxygen equipment ordered (type, LPM) and frequency of use.
