The One Word That Should Anchor
Every Wound Care Program: Utilization Management

Part 1 of 2: Building a shared vocabulary for the wound care case manager

Think about the most expensive wound in your panel. It usually isn’t the one with the priciest dressing or the most advanced therapy. It’s the one that keeps cycling back. The ulcer that almost heals, then gets infected, then sends the patient to the emergency department, then starts over from zero. The money isn’t in the product. It’s in everything that never got coordinated around it: the missed follow-ups, the compression that was ordered but never worn, the vascular referral that sat in a queue, the infection no one caught until it became an admission.

A complicated wound patient can cost the system tens of thousands of dollars a year. Published estimates put the cost of managing a single venous leg ulcer somewhere between $7,000 and $12,000 per patient per year, with lifetime costs that can exceed $40,000 and a total US payer burden approaching $15 billion annually (Kolluri et al., 2022). One avoidable hospital stay for a wound infection can add roughly $7,000 to $20,000 or more on top of that (Challener et al., 2017; Keyloun et al., 2018). The difference between a wound that heals on an outpatient path and one that spirals into repeat admissions usually comes down to coordination. And the spending is concentrated: across healthcare, roughly 10% of patients drive about 70% of total costs, which is exactly why aiming coordinated case management at the most complex patients pays off (Katz, 2024).

That coordination has a name, and it’s the single most important term in the wound care case manager’s vocabulary: utilization management. It’s also where the return on investment for this role lives.

Utilization management is the umbrella, and it belongs to the case manager

Utilization management (UM) is the professional process for systematically evaluating whether wound care services are appropriate, necessary, and efficient, before, during, and after the care is delivered. It isn’t a payer obstacle or a billing function bolted onto the side of a clinic – it’s the framework that every authorization request, every continued-stay review, and every post-payment audit lives inside.

UM is professional case management work. Done well, it’s owned by a trained clinician who can read a wound, read a coverage policy, translate between the two, and coordinate a team around both. That person is the wound care case manager. UM is their core discipline, not an administrative chore handed off to untrained personnel.

Underneath UM sits utilization review, the engine that does the work

If UM is the umbrella, utilization review (UR) is the engine underneath it. UR is the systematic clinical review of wound care services against evidence-based criteria, coverage policy, and the patient’s actual clinical picture. It comes in exactly three forms, sorted by when the review happens relative to the care. That before, during, and after structure is the established backbone of utilization management in case management practice (Katz, 2024).

• Prior authorization is the review before care. The provider asks the payer to approve a service, supply, or device before it’s delivered. For advanced wound care, this is the most consequential moment in the whole process. A complete, policy-aligned and LCD-aligned request that anticipates every coverage criterion is often the difference between a patient receiving evidence-based care on time and a patient stuck waiting through an avoidable denial. Prior authorization is patient advocacy carried out through documentation.
  
  
• Concurrent review is the review during care. While the patient is actively being treated, the wound care case manager rechecks that continued care remains medically necessary. This applies to inpatient stays, SNF stays, home health episodes, and mobile and HOPD wound centers for ongoing outpatient modalities such as NPWT, MIST therapy, and other advanced treatments, including debridements and HBOT. The case manager’s job here is to keep proving, at every assessment interval, that the skilled need is real and the wound is responding.
  
  
• Retrospective review is the review after care. After the claim is paid, an auditor reviews the record to confirm the care was necessary, appropriate, and correctly coded. Medicare does this through its MACs, Recovery Audit Contractors, and CERT program, and commercial payers run their own post-payment reviews and take-backs. When the documentation doesn’t hold up, the money gets recouped — and that outcome is usually decided long before the audit letter ever arrives, in the record built ahead of time.

The conceptual question that ties all three together

Here’s what I most want to standardize, because it’s the spine of everything above. Every one of those three reviews, before, during, and after, is really asking the same conceptual question: is the wound treatment actually helping this patient and healing the wound?

Prior authorization asks it in the future tense: is this treatment likely to heal the wound? Concurrent review asks it in the present tense: is it healing the wound right now? Retrospective review asks it in the past tense: did it heal the wound, and did the record prove it?

That’s the conceptual core of wound utilization review. The dimensions, the percentage-area reduction, the standard-of-care trial, the vascular assessment, the comorbidity workup — none of it is bureaucratic box-checking. It’s the evidence that answers the question that matters clinically and the question that matters to every payer. When the case manager keeps that question front and center, every review has a clear target: does the record, taken as a whole, answer it?

The case manager coordinates the team; they don’t do every job on it

None of this happens in a vacuum, and the case manager doesn’t do it alone. The provider writes the orders and signs the medical-necessity language. The wound nurse or case manager documents the bedside assessment. The biller and coder turn the care into claims. Specialists in vascular, endocrine, infectious disease, and nutrition own their pieces of the picture. The case manager’s job isn’t to write those notes — it’s to review them, judge whether, taken together, they answer the conceptual question, and pull in the right person to close the gap when they don’t. That matches how the role is defined in the field: the case manager reviews the chart and serves as a liaison among physicians, nurses, and other staff, coordinating care rather than delivering every aspect of it (Katz, 2024).

Think of it as air-traffic control: the case manager keeps the whole field in view, every authorization clock, every review interval, every contributor’s documentation, and keeps the planes from colliding. A prior authorization lapses before re-authorization. A vascular study never gets ordered. A note says “wound care” instead of spelling out a skilled need. Catching those gaps is what utilization management, utilization review, and concurrent review actually look like in practice, run across an interdisciplinary team rather than out of a silo.

More and more of the mechanical side of this will run on AI. Utilization management is already being automated: tools that flag stalled wounds, pre-check prior authorizations against coverage criteria, surface missing documentation, and watch the review clocks. That’s genuinely useful. But AI still needs a human in the loop, and in wound care that human is the case manager. A tool can flag that something doesn’t add up; the case manager decides whether it actually doesn’t, and why. A tool can generate the checklist; the case manager makes sure the provider, the home health agency, and the patient understand what needs to happen and why it matters. Someone has to refine the AI, and someone has to coordinate the people.

This is also where social determinants of health become real clinical data instead of a checkbox. When a wound stalls, the conceptual question demands an explanation, and that explanation is very often social: food insecurity undercutting the nutrition healing needs, no reliable transportation to follow-up visits, unstable housing, limited caregiver support, no way to afford or store supplies. The case manager gathers those SDOH metrics, then works with the patient and the interdisciplinary team to build a care plan that accounts for those roadblocks before they derail the chosen healing modality. Compression ordered for a patient who can’t afford the wraps, can’t get to the clinic to have them changed, and is on his feet ten hours a day is a treatment set up to fail. Captured well, that same SDOH data is both the clinical explanation for a slow-healing wound and part of the documentation that defends its medical necessity, and it’s work AI can’t do on its own.

Why now is the time to standardize the language

A wound care case manager doesn’t work in one place. They work in the hospital outpatient clinic, in the patient’s home through mobile wound care, alongside a home health agency, and inside long-term care. Each of those spaces has its own rules, and those rules can shift the steps of a given review slightly. That’s fine. What can’t change is what the terms mean. Prior authorization, concurrent review, and retrospective review have to mean essentially the same thing everywhere, including within a matching place of service, not just across different ones.

That last part is where most programs break down. “Concurrent review” should carry the same expectation in every HOPD department, across every mobile wound group, and at every home health agency. Right now it usually doesn’t. Too often there’s no deliberate concurrent review happening at all; no healing-metric expectations measured against the LCD, whether the patient is being seen in mobile wound care, in the HOPD, or in home health (Centers for Medicare & Medicaid Services [CMS], n.d.). In home health, especially, the only structured chart review that reliably happens is the OASIS data set, and that lands every 60 days – far too coarse to catch a wound that started stalling in week two.

Common language also does something practical that’s easy to overlook: it makes transitions of care work. When a patient moves from a wound clinic to a home health agency, or from one group to another, the handoff goes smoothly when everyone is using the same terms and documenting to the same standard. When the language drifts at the handoff, that’s exactly where wounds stall, infections get missed, and avoidable admissions happen.

That standardization isn’t a nice-to-have. A shared UM vocabulary, one that means the same thing across every HOPD, every mobile group, and every agency, is the operational backbone that protects both the patient’s access to care and the program’s bottom line. Building it, owning it, and running it is the primary responsibility of the professional wound care case manager.
