Medicare beneficiaries waiting on a wheelchair, a home ventilator, or a portable oxygen system have roughly twelve weeks before new federal paperwork requirements take effect, and the single most useful thing a patient or caregiver can do in that window is ask their supplier a short list of specific questions.
Starting October 28, a documented face-to-face visit with the treating practitioner will be required before delivery of 22 additional equipment types, including three home ventilator codes, eight wheelchair codes and one portable gaseous oxygen system. A separate and much smaller set of eight items will require Medicare's advance approval.
For most people, the change will be invisible, because the visit has usually already happened. The delays land on households in a predictable set of situations: a chair ordered after a hospital discharge by a clinician who is not the patient's regular doctor, a replacement piece of equipment ordered without a recent appointment, or an order written by a specialist last seen more than six months ago.
The Two Requirements That Get Confused Most Often
Almost every avoidable delay traces back to a household not knowing which of two requirements applies to their item.
A written order prior to delivery, paired with a face-to-face encounter, means the ordering clinician must have seen the patient within the six months before writing the order, and the written order has to reach the supplier before the equipment ships. There is no approval step and nothing to wait for from Medicare. In its notice, the agency said: "the written order/prescription must be communicated to the supplier prior to delivery."
Prior authorization is different. The supplier must submit documentation and receive a decision from Medicare or a review contractor before providing the item at all. This is the requirement that can be denied.
Only eight codes are being added to prior authorization: an air fluidized bed, the ultralightweight manual wheelchair code K0005, and six orthoses covering spinal, knee, elbow, and wrist devices. No ventilator and no oxygen code was added to that list. Federal regulation at 42 CFR 410.38 also allows a telehealth visit to satisfy the face-to-face requirement where clinically appropriate, which matters for homebound and rural patients.
Six Questions Worth Asking Before Anything Ships
The questions below are ordered roughly by how often they prevent a problem.
First, ask the supplier which HCPCS billing code they intend to submit. Requirements attach to the specific code, not the general category, and two similar-looking wheelchairs can carry different rules. K0005 needs prior authorization; K0004 does not.
Second, ask whether that code requires prior authorization or only a written order before delivery. If the answer is prior authorization, ask when the request was submitted and whether a decision has come back.
Third, ask the ordering clinician's office to confirm that a qualifying visit is documented within the past six months, and schedule one if it is not. Reviewers look for a note in the chart that includes the clinical reason for the equipment.
Fourth, ask for a copy of the written order for personal records. Households that keep their own copy resolve disputes faster.
Fifth, ask what documentation the supplier still needs from the clinician. Missing chart notes are a more common cause of delay than outright denial.
Sixth, if a request is denied, ask whether it can be resubmitted with additional documentation. A non-affirmed prior authorization decision is not a final coverage denial, and suppliers can submit again.
Where Delays Actually Come From
Understanding why Medicare is tightening documentation helps explain what reviewers are looking for.
The agency pointed to its Comprehensive Error Rate Testing program, which found orthoses, ventilators, oxygen equipment and hospital beds among the top 20 equipment types with improper payments in 2025. Improper payment rates for upper limb orthoses ran between roughly 40 and 48 percent from 2023 to 2025. For manual wheelchairs, the range was 22.1 to 42 percent.
Most of those improper payments are documentation failures rather than fraud, which is precisely why a well-documented clinical note is what moves an order through. CMS also said it can suspend the prior authorization program if it becomes aware that the process is creating barriers to care, and named 1-800-MEDICARE as a channel it monitors for complaints.
Medicare Advantage enrollees face a separate layer. Those plans must cover equipment at least as generously as original Medicare but set their own networks and authorization rules, so the questions above should be asked of the plan as well as the supplier.
Costs, Coverage and the Fall Timeline
None of this changes what equipment Medicare covers or what a beneficiary pays. Under Part B, patients generally pay 20 percent of the Medicare-approved amount after meeting the annual deductible, and equipment must come from a Medicare-enrolled supplier.
Households facing a gap can ask the supplier whether a rental option exists while documentation is completed, and can contact their State Health Insurance Assistance Program for free local counseling on coverage and appeals. Hospital discharge planners and social workers are often the fastest route to resolving a documentation problem before a patient goes home.
The timeline is firm. Most of the new requirements begin October 28. Prior authorization for elbow and wrist orthoses phases in by state, starting with New York, Michigan, Florida and California, expanding to eight more states in January 2027 and going nationwide in April 2027. CMS said it will publish detailed sub-regulatory guidance before implementation, and the current lists are posted on the CMS ordering requirements page.
Anyone expecting equipment in the fall should start the conversation with their clinician now rather than in late October. The paperwork is straightforward when it happens ahead of the order and slow when it happens after.
Frequently Asked Questions
Will my wheelchair or oxygen still be covered? Yes. Coverage rules are unchanged. What changes is the documentation a supplier must have on file before delivering the item and billing Medicare.
Which items now need Medicare's advance approval? Eight codes: an air fluidized bed, the ultralightweight manual wheelchair code K0005, and six spinal, knee, elbow, and wrist orthoses.
Do home ventilators need prior authorization? No. Three home ventilator codes were added to the face-to-face and written order list only.
Can a telehealth appointment satisfy the visit requirement? Federal regulation permits telehealth encounters where clinically appropriate. Confirm with the ordering clinician that the visit will be documented in a way that meets the requirement.
What should I do if my equipment is denied? Ask the supplier whether the request can be resubmitted with additional documentation from your clinician. A non-affirmed decision is not necessarily final.
When does this start? October 28 for most items. Prior authorization for elbow and wrist orthoses phases in by state through April 2027.
Does this apply to Medicare Advantage? Those plans must cover equipment at least as generously as original Medicare but set their own network and authorization rules. Check directly with your plan.
