If you have open indemnity claims on your book where the injured worker is approaching Medicare eligibility — or already there — there's a good chance the Medicare set-aside (MSA) allocation on that file is running 23% higher than it needs to be. And that's money coming out of your client's total claim cost, which feeds directly into their experience mod and future premiums.
What the Data Shows
A recent analysis published by Risk & Insurance found that when clinical intervention is applied to workers' comp MSA files, the resulting costs run roughly 23% below the national average. Clinical intervention, in this context, means a nurse or clinical specialist actively reviews the injured worker's treatment plan, medication regimen, and future medical needs — rather than relying solely on a formulaic allocation based on historical billing codes.
This a national workers' comp product manager, I'm seeing this play out on submissions where agents flag MSA exposure early — the files that get clinical review before settlement consistently come in with lower total cost estimates, and that difference shows up at renewal. What I'm watching for in submissions right now is whether the carrier or TPA has a clinical intervention protocol in place, because that's becoming a real differentiator in total claim outcomes.
This isn't a marginal difference. On a six-figure MSA, a 23% reduction can mean tens of thousands of dollars in lower total claim cost. For agents managing accounts in the $250K–$1M premium range, even one or two of these files can move the experience mod at renewal.
Why This Matters More Right Now
MSA costs have been a quiet driver of severity in workers' comp for years, but they're getting harder to ignore. As Risk & Insurance noted in a separate piece, medical cost inflation and aging workforces are two of the three major threats that could reshape the workers' comp market in the near term. MSAs sit right at the intersection of both: older injured workers with longer life expectancies and rising pharmacy costs produce larger allocations — unless someone is actively managing the clinical picture.
The problem is that many TPAs and MSA vendors still default to a "set it and forget it" allocation model. They run the numbers based on ICD codes and prescription history, submit the allocation to CMS, and move on. Clinical intervention requires a deliberate step — and it's a step that doesn't always happen unless someone on the file asks for it.
What to Do on Your Book This Week
Here's the specific move: run a report of every open indemnity claim where the injured worker is age 62 or older, has end-stage renal disease, or is receiving Social Security disability benefits. These are the files most likely to require an MSA at settlement. Then cross-reference that list against your TPA or carrier's MSA vendor records to see which ones have had a clinical intervention review.
For the ones that haven't, here's what to ask:
- Has a nurse or clinical specialist reviewed the treatment plan within the last 12 months? If not, request one before any settlement discussion.
- Is the medication regimen current and appropriate? Outdated prescriptions — especially long-term opioids or high-cost specialty drugs — inflate MSA allocations. A clinical review can identify tapering opportunities or therapeutic alternatives.
- Is the MSA allocation based on actual treatment patterns or just billing codes? Billing codes don't always reflect what the worker actually needs going forward. Clinical intervention closes that gap.
Document the answers in the file notes. If you're working with a carrier or TPA that doesn't offer clinical intervention as a standard service, that's worth knowing — and worth raising at your next service review.
What This Means for Your Placements
MSA costs don't show up on a loss run the way indemnity and medical payments do, but they hit the experience mod just the same when the claim settles. In a soft market where every basis point on the mod matters, agents who proactively manage MSA files are giving their clients a real edge. The 23% savings figure from the Risk & Insurance analysis isn't theoretical — it's a benchmark you can use to pressure-test whether your TPA or MSA vendor is doing the clinical work or just running the formula.
Start with the Medicare-eligible files on your book. Flag the ones without clinical review. Ask the question. It takes five minutes per file and can save your client five figures on a single settlement.
