Medicaid is run by each state within federal rules, so CPAP or oxygen coverage in one state can look different in another. Here’s what the federal rule guarantees, and how to work your state’s process.
The federal rule: 42 CFR 440.70
Medicaid’s home health services include “medical supplies, equipment, and appliances suitable for use in any setting in which normal life activities take place” (42 CFR 440.70). Key points from the regulation:
| Provision | What it says |
|---|---|
| Supplies | Health care items that are consumable or disposable, or can’t withstand repeated use by more than one person, required for a medical disability, illness or injury |
| Equipment and appliances | Primarily and customarily used for a medical purpose, generally not useful without a disability, illness or injury, withstand repeated use, can be reusable or removable |
| Not limited to Medicare’s list | State coverage “is not restricted to the items covered as durable medical equipment in the Medicare program” |
| Annual review | Need must be reviewed by a physician or other licensed practitioner annually; further review case by case |
| Preapproved lists | Allowed for administrative ease, but no absolute exclusions |
| Requests for unlisted items | States must have a process using reasonable, specific criteria |
| Denials | The state must inform you of your right to a fair hearing |
How CPAP and oxygen typically fit
CPAP machines, masks and supplies, and home oxygen equipment all fit the federal definitions of equipment and supplies above. The specifics, including whether prior authorization is needed, adherence requirements, rental vs purchase, and replacement schedules, are set by your state or your Medicaid managed care plan. HHZ hasn’t compiled state-by-state criteria; check your state’s provider manual or member handbook.
Steps to get CPAP or oxygen through Medicaid
| Step | What to do |
|---|---|
| 1 | See a Medicaid-enrolled clinician; get evaluated and tested (home vs in-lab sleep test) |
| 2 | Ask which DME suppliers are enrolled with your state Medicaid or plan |
| 3 | The supplier or clinician submits the order and any prior authorization |
| 4 | Keep copies of your sleep test, prescription and any denial letters |
| 5 | If denied, ask for the written reason and request a fair hearing if you disagree (federal rule) |
| 6 | Plan for the annual practitioner review of your continuing need |
If the item isn’t on your state’s list
The federal rule says a state can’t refuse simply because an item isn’t on its preapproved list. It must have a request process with reasonable, specific criteria (42 CFR 440.70). Ask your caseworker or plan how to submit an exception request, and include your clinician’s documentation of medical need.
Medicaid vs Medicare for DME
| Medicaid | Original Medicare | |
|---|---|---|
| Who sets criteria | Each state, within federal rules | National and DME MAC policies |
| Covered items | Not restricted to Medicare’s DME list | Medicare DME definitions |
| Your cost | Set by your state; check its cost-sharing rules | Usually 20% after the Part B deductible (Medicare.gov) |
| Appeal | Fair hearing | Medicare appeals process |
Verdict
Medicaid’s federal rules protect you more than you might expect. Equipment isn’t limited to Medicare’s list, unlisted items can be requested, and denials come with fair-hearing rights. The details depend on your state, so get your state’s DME rules and enrolled supplier list, keep your documentation, and appeal in writing if you’re denied.
