Private insurance: medical policy, prior authorization and appeals

Is an alternating pressure mattress covered by health insurance?

Generally yes, as a category, when the plan's criteria are met. Alternating pressure and low air loss surfaces are powered pressure-reducing mattresses and overlays, and they sit in the tier Medicare calls Group 2 — the codes E0277 for a powered mattress and E0372 for a powered overlay, with E0371 and E0373 covering the advanced non-powered equivalents. Commercial plans typically recognize the same structure and write their criteria against it.

What that "generally yes" is doing a lot of work to hide is the conditionality. Coverage of a category is not coverage of your request. The plan has to be satisfied that the clinical criteria are met, that a lower level of support surface was tried and documented, that prior authorization was obtained where required, and that the supplier is in network. Any one of those failing produces a denial that has nothing to do with whether the person needs the mattress.

The criteria themselves usually look like this: multiple stage 2 pressure ulcers on the trunk or pelvis that have not improved over a month of comprehensive treatment; or large or multiple stage 3 or stage 4 ulcers on the trunk or pelvis; or a recent myocutaneous flap or skin graft for a pressure ulcer on the trunk or pelvis with a qualifying prior surface and discharge. Those are the Medicare Group 2 criteria, and plans adapt rather than reinvent them. Your plan's exact wording is in its policy.

What a medical policy is, and why you want it

A medical policy — some plans call it a clinical policy bulletin, a coverage guideline, or a medical coverage determination — is the document a reviewer applies when deciding a request. It names the item or category, sets out the criteria for medical necessity, and lists what the plan considers experimental, investigational or unproven. It is written for clinicians but is not hard to read, and it is usually public.

Two sections matter most to a family. The criteria section tells you what the record has to show, which lets you check the documentation before it goes in rather than after it comes back. The investigational section tells you what the plan will not pay for at any level of documentation — and that is a different kind of no, because no amount of additional evidence will move it.

Ask for the policy by name, get the version number and date, and keep a copy. Policies are revised, and a denial applied under a superseded version is a thing that happens.

Where fluid immersion simulation sits, plainly

There is no HCPCS code for fluid immersion simulation. Codes are how equipment enters the payment system, and without one there is nothing for a plan to authorize, price or pay against. That is true of every commercial plan, not just some of them, and it is the reason we describe the route to a Dolphin FIS system as private rather than as a coverage question.

Beyond coding, Aetna's Clinical Policy Bulletin 0430 on pressure reducing support surfaces lists Fluid Immersion Simulation among items it considers experimental, investigational or unproven. The bulletin specifically determines that the FIS system, naming Dolphin FIS as the example, is institutional equipment that is inappropriate for home use, on the reasoning that there is insufficient evidence of effectiveness in the home setting.

We are not going to argue with that on our own website, and we are not going to hide it either. It is one major payer's published determination. It does not prevent a hospital, a long-term care facility or a family from choosing the surface, and it is not a statement about what a wound-care clinician should recommend. It is a statement about what that plan will pay for, and it is the single most important thing an insurance page on this site could tell you.

The practical consequence is simple. If your route to this equipment depends on an insurer paying for it, that route is unlikely to exist. If the care team has specifically asked for fluid immersion simulation and the household is funding it, we can help with that, privately, and we will be straight with you about what it costs and what it does not come with.

Prior authorization, in practice

Prior authorization is a review that happens before the equipment is supplied. The ordering clinician or the supplier submits the request with clinical documentation, a reviewer applies the policy, and the plan approves, denies, or returns it for more information. The last of those is the most common and the one that eats the most days, because a request sitting in a queue for more information looks identical, from the outside, to one being decided.

Timelines are published in the plan's materials, and most plans operate an expedited pathway where a delay would jeopardise the person's health or where a hospital discharge is pending. Expedited review is frequently available and infrequently offered; ask for it by name, and have the discharge date to hand when you do.

The most useful thing a family can do is own the handoffs. Confirm the request was actually submitted, and by whom. Confirm the plan received it. Confirm what is outstanding. Each of those is a single phone call, and each one routinely discovers that something everyone assumed had happened had not.

• Get the reference number for the authorization request on the day it is submitted.
• Ask who at the plan is reviewing it and what the published decision timeframe is.
• Ask explicitly whether an expedited review applies to a pending discharge.
• Ask what documentation is outstanding, and get that answer in writing.
• If a denial is likely, ask the ordering clinician to request a peer-to-peer review before the decision is issued.

Networks, and the supplier problem nobody warns you about

A durable medical equipment supplier has to be contracted with your specific plan for the specific code being billed. Not with the insurer in general — with the plan. The same insurer administers employer plans, individual marketplace plans and Medicare Advantage plans with different networks, and a supplier who is in network for one may be out of network for another.

Out-of-network supply produces a bill the household was not expecting, or an outright non-covered determination, and it is discovered after delivery more often than before it. Ask the plan for the list, and ask the supplier to confirm network status for your plan name and group number, not for the logo on the card.

We are not in anyone's network. We are not a contracted DME supplier, we do not bill insurers, and we do not accept assignment of benefits. That is a limitation and we state it as one: what we offer is a private transaction, which sometimes matters when a discharge date is fixed and an authorization is not, and which is the wrong answer when a covered route exists.

If a request is denied

The denial letter is the document that matters. It states the reason, cites the policy criterion the reviewer found unmet, and sets out the appeal levels and deadlines. Read it for the criterion rather than for the tone. Most first-level denials of support surfaces come down to something the record did not show — the duration of the prior surface, the documented turning schedule, the nutritional intervention, the wound measurements over time — rather than to a disagreement about whether the person is unwell.

Internal appeal comes first, handled by the plan. Where the internal appeal fails, most plans also offer an independent external review by a reviewer not employed by the insurer, and the denial letter will say how to request one and by when. The deadlines are shorter than people expect and are not extended for the reason that the family was busy caring for someone.

Practical division of labor: the clinician supplies the clinical argument, the supplier supplies the coding and delivery record, and the household chases the handoffs and keeps the calendar. Where an investigational determination rather than a criteria failure is the basis of the denial, be realistic — that is a policy position, not a documentation gap, and the time may be better spent on the alternatives the policy does cover.

Other payers that are not health insurance

Not every funded route is a health plan. Where an injury is work-related, a workers' compensation claim funds equipment under its own rules, with its own adjuster, its own authorization process and often a wider view of what is reasonable and necessary than a group health plan takes. Where an injury arose from a motor vehicle collision, medical payments coverage or a liability settlement may be the route, and equipment costs are frequently part of a life-care plan prepared for the case.

These routes have one thing in common: the decision-maker is not a medical policy reviewer, and the documentation that persuades them is different. If a case manager, adjuster or life-care planner is involved, they are the person to ask, and they will usually tell you exactly what they need to authorize a purchase. We can supply confirmed specifications and an itemised quote for that file, which is often all that is wanted from the equipment side.
