LOP Economics: Real Yield vs Face Value

A $4,200 MRI billed to a Letter of Protection case is not a $4,200 receivable.

It is a contingent legal claim with a 280-day median settlement timeline and a 65% negotiated final yield — which, in expected-value terms, makes it roughly a $2,730 receivable that won't convert into cash for nine months. Two imaging centers with identical $4M LOP balances on their aging report can have wildly different cash realities. One is sitting on $2.6M of real recoverable yield. The other is sitting on $1.4M.

Most SE Florida imaging operators run their books on the first version. Most lenders, when they finally diligence the asset, run their analysis on the second. The gap between those two numbers is where covenant problems get born.

This article is the LOP yield framework we apply inside every Strategic Radiology Review — built specifically for SE Florida multi-center imaging operators where attorney-driven volume is structurally embedded in the payer mix.

Key Takeaway: Letter of Protection receivables behave like contingent claims on legal settlements, not commercial A/R. The four variables that determine real yield — settlement timeline, negotiated final percentage, attorney/firm concentration, and statute exposure — produce expected-value markdowns of 35–50% against face value at most SE Florida imaging centers. Operators carrying LOP at gross face value are not committing fraud — they are signing up for an avoidable surprise the next time a lender runs their own diligence. The yield-adjusted reserve framework below is how to run the conversation before the bank does.

What an LOP Actually Is

A Letter of Protection is a written agreement, typically signed by a personal-injury attorney on behalf of an injured client, in which the attorney commits to pay the medical provider out of any settlement or judgment proceeds in the underlying tort case. It is not insurance. It is not a guarantee. It is a contingent obligation that converts to cash if and only if:

1. The underlying personal-injury case settles or wins at trial
2. The settlement amount is large enough to cover the LOP after attorney fees, costs, and any superior liens
3. The medical bill is not negotiated down at the back end of the case
4. The attorney's office actually disburses the funds in a reasonable window

Each of those four conditions has a probability and a timeline. Multiply them together and you get the real yield. Almost no imaging center actually does this math. Most just bill at face value, age the receivable forward, and hope.

For a longer treatment of why LOP-heavy practices show 20+ months of A/R as a structural feature rather than a billing failure, see Why PI-Heavy Medical Practices Carry 20+ Months of A/R — The LOP Cash Cycle Explained. This article extends that framing into the explicit yield-adjustment math.

The Four Variables That Determine Real Yield

Variable 1 — Settlement Timeline

The clock starts when the injury occurs, not when the scan happens. By the time an injured person reaches an imaging center, the case may already be 60–180 days into its lifecycle. From scan to settlement, the additional median elapsed time at most SE Florida personal-injury practices runs:

• Soft-tissue cases (MRI, X-ray for lumbar/cervical): 180–360 days from scan to settlement
• Mid-complexity cases with imaging escalation: 360–540 days
• Severe / contested / multi-defendant cases: 540 days to 3+ years

The longer the case, the higher the discount required for the time value of money — and the higher the risk of the attorney leaving, the firm changing, or the case going dormant.

Variable 2 — Negotiated Final Yield

Even when a case settles, the medical bill rarely settles at face value. Personal-injury attorneys are professional negotiators, and the LOP balance is one of the line items they negotiate down — often aggressively — to maximize the client's net recovery.

Typical negotiated yields at SE Florida imaging centers:

• Tier-1 firms (large, well-established, repeat-relationship): 70–85% of face value
• Tier-2 firms (mid-sized, mixed track record): 50–70% of face value
• Tier-3 / unknown firms: 30–55% of face value, with elevated bad-debt risk
• Self-represented or unrepresented: 10–40%, with the highest non-collection rate

A center with 60% of LOP volume tied to Tier-1 firms is fundamentally a different financial entity than one with 60% tied to Tier-3. Both will have identical face-value A/R reports.

Variable 3 — Attorney / Firm Concentration

Concentration risk in LOP A/R is structurally similar to customer concentration in any small business. If 40% of your LOP balance is with a single attorney's office, the cash flow of your imaging center is now downstream of one law firm's case docket, settlement strategy, and negotiation behavior.

The diagnostic question every imaging operator should be able to answer in under five minutes: What share of my LOP A/R is concentrated in my top three referring attorneys, and what is each one's historical realization rate against my billed amounts?

If you can't answer that, you don't have an LOP A/R management system — you have an LOP A/R hope system.

Variable 4 — Statute Exposure on Aged Cases

Florida's statute of limitations on most personal-injury claims is two years from the date of injury (F.S. 95.11) — meaning LOP balances tied to cases approaching the statutory window face binary outcomes: settle/file or worthless. Aged LOP receivables are not just slow — they are increasingly contingent on a single procedural event.

The math implication: an LOP balance aged 540+ days needs to be treated as a substantially different asset from one aged 180 days. Most imaging-center aging reports do not make this distinction.

The Yield-Adjusted Reserve Framework

Apply the four variables and you get a yield-adjusted reserve calculation that operators, controllers, and lenders can all reconcile to. Here's the framework on a representative SE Florida $10M-revenue imaging center carrying $4.0M of gross LOP A/R:

The center's face-value A/R is $4.0M. The center's yield-adjusted A/R is $2.47M. That is a $1.53M markdown — 38.3% — embedded in a single line on the balance sheet that almost no operator actually quantifies.

This is not a write-down for accounting purposes. The gross balance stays on the books for tax, billing, and compliance. The yield-adjusted figure is a management reporting overlay that gives the operator and the lender a real cash-equivalent number to plan against.

Why Lenders Already Run This Math

Banks underwriting A/R-backed lines of credit at SE Florida imaging centers in 2026 are not naive about LOP. They have seen the yield curves at multiple operators, they know the realization patterns, and most A/R-backed underwriting departments now apply standardized markdowns:

• Commercial and Medicare A/R: 80–85% advance rate (standard)
• PIP A/R: 50–65% advance rate (slow but predictable)
• LOP A/R Tier-1 firms, under 365 days: 30–45% advance rate
• LOP A/R Tier-2 / aged 365-720 days: 15–25% advance rate
• LOP A/R aged 720+ days or Tier-3: 0–10% advance rate, often excluded from borrowing base

Operators showing up to a renewal with an aging report based on face value get blindsided. The lender's term sheet comes back with a borrowing base 30–40% smaller than what the operator was modeling against — not because anything in the operation has changed, but because the lender is now applying yield logic that the operator never made visible internally.

The right move is to own the yield-adjusted number first, build it into the lender presentation deck, and walk into the renewal conversation with the markdown already disclosed. (See: Radiology Accounts Receivable: How Banks Misread Your Aging Report — the related article on aging-report translation.)

The Modality Distortion

LOP exposure is not evenly distributed across modalities. At a typical SE Florida multi-center imaging operator, the modality-by-modality LOP share looks roughly like this:

• MRI (cervical, lumbar, knee): highest LOP exposure, often 35–55% of total volume
• X-ray: moderate-to-high, 20–35%
• CT: lower, 10–25%, biased toward post-trauma and head-injury cases
• Ultrasound / DEXA: low, 5–15%
• PET Tracer Scans: typically near zero for LOP volume

This means modality mix at a center can dramatically shift the underlying LOP-to-commercial blend even when total volume looks stable. A center growing MRI faster than CT and PET Tracer Scans is, all else equal, growing its LOP exposure — which means growing the gap between face-value A/R and yield-adjusted A/R.

This is a strategic pricing and capacity-allocation conversation that operators almost never have at the modality level, because their accounting and billing reports don't surface modality-level LOP economics. (For more on the per-modality profitability frame: see our per-modality profitability article.)

The Tax Layer

LOP receivables also create a tax-timing discipline that most imaging operators handle poorly. Cash-basis taxpayers don't recognize LOP income until cash is received — which is correct, and creates no tax timing risk. Accrual-basis taxpayers recognize LOP revenue when billed, which can produce real tax exposure on receivables that won't collect for 18+ months at a discounted rate.

The right structure for accrual-basis imaging centers carrying significant LOP volume:

1. Recognize gross billings at full value (matches the books)
2. Establish a documented bad-debt reserve methodology tied to historical realization rates
3. Adjust the reserve quarterly based on actual yield experience, not face-value aging
4. Make sure the methodology is consistent year-over-year (changes can trigger Section 481(a) adjustments)

This is one of the silent areas where competent tax work and real management reporting converge. The IRS allows reasonable bad-debt reserves; the lender wants yield-adjusted A/R; the owner wants real cash-equivalent numbers. All three converge on the same yield analysis — but only if someone is doing it.

Five Actions for SE Florida Imaging Operators

1. Build a referring-attorney concentration report this quarter. Pull every LOP receivable, group by attorney/firm, sort by face-value balance. The top 10 attorneys are likely 60–75% of your LOP A/R. That single report is the foundation of every conversation that follows.

2. Run a 24-month look-back on realization rates by attorney tier. For each closed LOP case in the last 24 months, capture: face-value billed, settlement amount, days to settlement. Compute realization rate and median timeline by attorney tier. This is your empirical yield curve. Generic industry numbers are a starting point — your own data is the real input.

3. Apply yield-adjusted markdowns to your management reporting. Keep gross face value on the books. Add a yield-adjusted column to internal A/R reports. Run lender conversations and capital decisions on the yield-adjusted figure.

4. Bring the markdown to your lender voluntarily. The lender will run this analysis whether you do or not. Owning the disclosure first protects credibility, signals operational sophistication, and often produces a more favorable advance-rate negotiation than waiting to be discovered.

5. Re-evaluate modality mix in light of LOP exposure. If MRI is growing as a share of volume and your LOP yield is unfavorable in the MRI bucket, you are quietly growing a low-yield asset. Capacity allocation, marketing focus, and referrer development decisions should reflect modality-level yield economics — not just modality-level volume.

What This Looks Like for an Operator

Your billing company can pull the data. Your accountant can model the tax implications. Your lender already knows the answer. The question is whether anyone is integrating those three views into a single yield-adjusted picture you can act on.

A multi-center SE Florida imaging operator we worked with came into a Strategic Radiology Review carrying $4.6M of LOP A/R at face value. The owner believed, correctly, that the receivables would eventually convert. He believed, incorrectly, that they would convert at face value. The yield analysis dropped the real expected value to $2.81M — a 39% markdown. Two of the top-five referring attorneys were Tier-3, with sub-50% historical realization, accounting for $890K of the gap by themselves.

The operator did not panic. He did three things in 30 days. He shifted referral cultivation effort toward the Tier-1 firms with documented 75%+ realization. He renegotiated billing protocols on Tier-3 cases to require partial point-of-service collection. And he walked into his next lender review with the yield-adjusted number on slide three of the deck.

Most accounting firms see a healthy aging report and move on. The operator sees a healthy headline. Both are looking at the same number — and both are missing the same problem. This is what happens when accounting stops looking backward and starts looking forward. (Read how accounting becomes an ROI center, not a cost center.)

The bank renewed the line at a higher advance rate than the prior year, because the operator was now the most credible person in the room about his own A/R. The Monday after that meeting, the CFO told us the conversation was the first one in three years where he wasn't bracing for a surprise.

Frequently Asked Questions

What discount should I apply to LOP receivables? There is no single discount, because LOP yield depends on attorney tier, settlement timeline, modality, and statute exposure. SE Florida imaging operators typically see blended markdowns of 35–50% against face value once the four-variable framework is applied. Tier-1 attorney concentrations produce smaller markdowns (15–25%); Tier-3 and unrepresented exposure can require 50–70% markdowns or full exclusion.

Should LOP receivables be on the borrowing base? Yes, but with a tiered advance rate, not a flat rate. Most A/R-backed lenders in 2026 will lend 30–45% against Tier-1, current-aged LOP; 15–25% against Tier-2 or moderately-aged LOP; and exclude Tier-3 or LOP aged past 720 days. The right move is to bring this analysis to the lender first, before the underwriter discovers it.

How long do LOP receivables typically take to convert? Median timelines run 220–540 days from scan to cash, depending on case complexity, attorney tier, and modality. Soft-tissue cases settle faster (often inside 12 months); contested or multi-defendant cases can stretch 18–36 months or longer. Aged LOP balances past 540 days face binary statute outcomes that change the asset's character entirely.

Are LOP balances written off if a case loses at trial? Generally yes, with the legal nuances depending on the LOP terms. Most LOP agreements protect the medical provider only to the extent of settlement or recovery proceeds. A case that loses at trial typically extinguishes the LOP — which is why concentration in firms with weak case-selection discipline is a real bad-debt risk, not just a slow-pay risk.

Can I use LOP yield analysis for my tax bad-debt reserve? Accrual-basis imaging centers can establish a documented bad-debt reserve methodology tied to historical realization rates, subject to standard IRS rules on consistency and documentation. The yield analysis described in this article forms a defensible empirical basis for that reserve — but the specific reserve mechanics should be set with your tax preparer, with attention to Section 166 specifics for accrual taxpayers.
