One Language, Every Setting: Utilization Management
from the Wound Clinic to the Nursing Home

In Part 1, I made the case for treating utilization management as the core discipline of the wound care case manager, and for defining its three review types (prior authorization before care, concurrent review during care, and retrospective review after care) as one shared vocabulary. Underneath all three sits the same conceptual question: is this treatment actually helping the patient and healing the wound?

I want to show why that shared vocabulary matters by walking those three reviews through the four settings a case manager actually works in. The terms don’t change. The expectations don’t change. What changes is the mechanics on the ground, and how much weight falls on the case manager to fill in what the setting itself doesn’t provide.

The Wound Clinic (HOPD, POS 22 or 19; Freestanding, POS 11)

This is where advanced wound care is most concentrated, and prior authorization carries the most weight. Before an advanced therapy like NPWT, a course of MIST, or HBOT, the case manager reviews the provider’s order and the wound nurse’s assessment against the applicable coverage policy, typically the relevant Local Coverage Determination (Centers for Medicare & Medicaid Services [CMS], n.d.-b). They’re checking that the request is complete before it leaves the building: a documented standard-of-care trial, serial measurements showing failure to progress, a vascular assessment, confirmed diagnosis codes. The case manager doesn’t author any of those records. Their job is to verify that the record holds the pieces together and then sends the gaps back to whoever owns them. Concurrent review then governs the episode: tracking sessions against the authorized schedule, confirming the chart shows the wound responding visit to visit. Because the clinic is the highest-volume biller of these services, it also carries the heaviest retrospective-review exposure. This is the setting where the underlying question gets asked in its purest form, over and over.

Mobile Wound Care (Patient Home, POS 12)

This is probably the setting people misunderstand most, and the misunderstanding is a utilization-management one. A clinician traveling to the home bills professional services under Part B and doesn’t need homebound status or home health conditions of participation to do it. That freedom comes with a cost: there’s no OASIS, no 60-day certification, no agency structure wrapping the visit. All of that coordination has to come from somewhere else, and it’s the case manager who supplies it. They review what the traveling clinician brings back, make sure prior authorization, serial measurements, and audit-ready records keep pace, and route anything missing to the provider. The home also makes social barriers visible in a way a clinic visit never does: the empty refrigerator, the stairs the patient can’t manage, supplies stored the wrong way. That makes it a good place to capture SDOH information and feed it directly into the care plan.

The Home Health Agency (HHA, POS 12)

Concurrent review dominates here, and the interdisciplinary team is at its largest. The Medicare home health benefit requires certified homebound status and a documented skilled need, renewed every 60-day certification period. The case manager is constantly checking that the visiting nurse’s documentation demonstrates the skilled wound care need.   “Wound care” on its own is never a sufficient skilled-need statement. “Wound assessment requiring clinical judgment to distinguish healing granulation and infection prevention education” is. The nurse writes that language, but the case manager is the one making sure it’s there at every visit, alongside functional status and serial measurements, because that’s what keeps the authorization alive. The home health team also includes therapy, aides, and social work, which makes this the natural place to turn SDOH findings into an actual plan: looping in the dietitian for a protein deficit, social work for a transportation barrier, so the treatment has a real chance to work. Weighing psychosocial factors and community resources alongside the clinical picture, then building the plan around them, is core case management rather than an add-on (Katz, 2024). And because the HHA folds wound supplies into its episode payment, utilization decisions made at the bedside are financial decisions too.

Long-Term Care (Nursing Facility, POS 32)

This is the setting most likely to get left out of a wound case management program entirely, and leaving it out is a liability. Custodial LTC isn’t a Medicare-covered skilled benefit (Medicaid is the primary payer here), but the professional wound visits by physicians, APRNs, and PAs are billed under Part B and are reviewable. More importantly, facility-acquired pressure injuries are tracked through the MDS and reported publicly on Care Compare, where they drive Star ratings (CMS, n.d.-a). The underlying question takes on a prevention angle in this setting, and it’s answered by a team the case manager coordinates rather than replaces: facility nurses, dietary, therapy, etc. Applying the same UM discipline to surveillance, nutrition, offloading, and early intervention here has a direct, measurable effect on both patient outcomes and the facility’s quality standing.

When the language and the expectations stay identical across all four settings, the program has a standard. When they drift, that’s when a wound patient slips through the cracks of care.

Where the ROI Lives: One Genuinely Complicated Patient

Picture a 60-year-old factory worker, years away from retirement, with diabetes and now a diabetic foot ulcer. He’s on a high-deductible commercial plan, so early in the plan year he’s paying nearly full price out of pocket for every visit, every dressing, every supply. What worries him most isn’t the wound itself. It’s that he can’t afford to be off his feet or out of work for long, because his paycheck is what keeps his family afloat. When the team hands him an offloading boot, the single most important thing for healing this wound, he isn’t happy about it. It’s awkward, it slows him down on the factory floor, and because of his deductible, it’s coming straight out of his own pocket.

Here’s the clinical bind. A diabetic foot ulcer heals when the pressure comes off it, and consistent offloading is the gold standard for that. But he’s standing and walking on a factory floor all day, which is exactly what makes a diabetic foot ulcer worse. The offloading device that would protect his wound is the one he can least afford and least wants to wear. The wound also needs good blood flow and controlled blood sugar to heal, so perfusion and glycemic control are on the table too. If the offloading fails and the wound stalls, the risk of infection, osteomyelitis, hospitalization….and ultimately amputation…. greatly increases. It’s easy to underestimate what’s at stake with one wound: five-year mortality after a diabetic foot ulcer runs around 30%, and after a major amputation it climbs to roughly 57%, comparable to, and in the amputation case worse than, the pooled five-year mortality across cancers (Armstrong et al., 2020).

This is where utilization management stops being paperwork and becomes patient care.

On prior authorization, the case manager secures approval for the offloading device, the dressings, the diagnostic workup, and then goes to work on the cost barriers to care. The wound case manager may consider enrolling him in manufacturer assistance and charitable programs to cover the offloading and dressings he otherwise can’t afford, and finding covered options his plan will pay for. They also check whether his commercial plan gives him access to a case manager of his own, because that person may be able to unlock benefits and resources he doesn’t know he has. On concurrent review, the case manager keeps proving the wound is responding at each interval so the care stays authorized and the skilled need stays documented, and they adjust the plan the moment the wound stalls. On retrospective readiness, they build the record as they go: the offloading plan and adherence, the serial measurements, the vascular results, the diabetes management, the financial and work barriers that explain the wound’s course, so that if the payer reviews or denies, the documentation holds up.

Then there’s the work the textbook doesn’t call utilization management but absolutely is. The case manager sits down with the patient and his caregiver on diabetic foot ulcer education: what offloading actually does, how to inspect the foot every day, what early infection looks like, so the two people living with this wound understand what must happen and why. The case manager stays in frequent contact with the patient between visits, because the call that catches early redness, warmth, or drainage is the call that prevents the admission (Katz, 2024). They help the patient understand the benefits available through his job, FMLA and any accommodations included, so he can protect both his wound and his paycheck instead of being forced to choose between them. They make sure he’s set up with diabetes education, because a foot ulcer isn’t going to heal on top of uncontrolled glucose. The case manager also follows up on the patient’s vascular studies, because if his blood flow is compromised, nothing else on the plan works until that’s addressed.

None of this happens in one person’s head. The case manager is coordinating the wound provider and podiatry, the PCP managing his diabetes, vascular for the perfusion question, the diabetes educator, his commercial insurance case manager for benefits and assistance, and, in a way most programs forget, his employer’s leave and accommodation process. The case manager isn’t writing everyone’s notes. They’re keeping everyone pointed at the same patient, working from the same plan, and asking the same question: is this wound actually healing, and if not, what’s in the way?

Now the return on investment. Chronic wounds already reach nearly 15% of Medicare beneficiaries and cost the program somewhere between $28 and $97 billion a year, with diabetic foot ulcers among the most expensive wound types on that list (Nussbaum et al., 2018). The direct cost of diabetic lower-extremity care rivals the cost of treating cancer, which fits outcomes that are every bit as serious (Armstrong et al., 2020). This is the logic behind high-cost case management: it concentrates on the small share of patients, often the 1% to 7% who account for 30% to 60% of a group’s total spending, where focused coordination actually changes the trajectory (Katz, 2024). A case manager who keeps this man working, gets the offloading to stick, controls the infection risk, and heads off an amputation returns far more than the position costs. That’s not a soft benefit. That’s the business case, and the patient gets to keep his job and his foot.

Professional Wound Care Case Management

Wounds are getting more complex, patients are moving across more settings, and the financial pressure on both patients and programs keeps rising. Programs that treat utilization management as a named, owned, standardized discipline,  with shared vocabulary and expectations from wound clinic to nursing home, heal more wounds, prevent more admissions, and can prove their value.

This work needs an owner, and the professional wound care case manager is it. Not the person writing every note, but the one keeping utilization management, utilization review, and concurrent review moving in sync across the provider, the wound nurse, the billers, the specialists, the payer, and the patient. Defining these terms clearly, making them standard across the wound care industry, and running them consistently across every place of service isn’t a support role on the margins of wound care. It’s the job, and it pays for itself.
