Conservative PI Case Management: Why Top Firms Reject 78% of Cases

The Call You Don't Take Is Worth More Than the One You Do

It's Monday at 8:45am. Your intake coordinator has 14 new leads from the weekend. Seven are rear-end collisions. Three involve slip-and-falls at chain restaurants. Two are rideshare incidents. One is a commercial truck case with an FMCSA logbook violation. One is a low-speed parking lot fender-bender where the caller says he "can't turn his neck."

You have capacity for maybe four new files this month without burning out your paralegals. Which ones do you take?

This is where conservative PI case management starts. Not with the cases you accept. With the speed and discipline of the ones you reject. The best-run plaintiff firms we've worked with don't agonize over this decision. They've built intake criteria that are almost algorithmic in their precision, anchored to crash physics, medical documentation timelines, and liability clarity. And they kill most files in under six minutes.

The number that keeps surfacing in our conversations with managing partners: roughly 78% of potential cases get rejected or referred out. That's not a sign of timidity. It's portfolio management applied to a trial docket.

What the Rejection Rate Actually Tells You

A 78% rejection rate sounds aggressive until you look at what happens to firms that take everything.

The math is straightforward. The average plaintiff's firm spends between $8,000 and $15,000 in hard costs per litigated BI case before settlement or trial, according to data published by the American Association for Justice. That includes medical record retrieval, expert depositions, filing fees, and staff time. If a case settles for $35,000 on a standard contingency, the firm nets roughly $11,600 before overhead. If it doesn't settle, and you've invested $12,000 in costs, you're underwater before the jury sits down.

Firms that reject 78% of incoming inquiries aren't leaving money on the table. They're refusing to subsidize weak files with the revenue from strong ones. Every hour your senior paralegal spends chasing an MRI authorization on a case with a Delta-V under 5 mph and no objective findings is an hour she isn't building a demand package on your $400K trucking case.

That's the real cost of poor case selection. It's invisible, and it compounds.

Three Tiers of Intake Filtering

The firms with the tightest intake processes tend to operate on three filters, applied in sequence.

Filter 1: Liability clarity. Can you establish fault in under 10 minutes with the information available? A police report assigning fault. A rear-end with the caller as the lead vehicle. A clear traffic camera angle. If liability is contested, muddled, or depends entirely on witness credibility, the case needs a higher injury threshold to justify the fight. Some firms set that threshold at AIS 3 or above for disputed-liability cases. Below that, they refer out.

Filter 2: Crash severity vs. claimed injury. This is the filter most firms get wrong, or skip entirely. A caller reports a herniated disc at C5-C6. But the photos show a cracked bumper cover and nothing else. No airbag deployment. No visible structural deformation. The damage-to-injury mismatch is the single most exploited weakness in defense strategy. If you can't answer the question "what was the Delta-V in this crash?" before you sign the retainer, you're flying blind.

This is where we've seen the sharpest shift in firm behavior over the past two years. Intake teams are running crash photos through Silent Witness's free Delta-V calculator during the initial call. A 12 mph Delta-V in a rear-end gives you a defensible biomechanical foundation for cervical strain claims. A 4 mph Delta-V with a herniated disc claim is a case the defense will dismantle with a MIST argument before you reach mediation.

Filter 3: Treatment timeline and documentation. Did the caller seek treatment within 72 hours? Is there a treating physician (not a chiropractor-only chain with a lien mill reputation) who will document objective findings? Gaps in treatment longer than 14 days in the first 90 days post-crash are, in the experience of every defense attorney we've spoken to, the first thing they flag.

The MIST Problem and Why It Starts at Intake

Minor Impact Soft Tissue. Four words that have ended more PI cases than any judicial ruling.

The MIST defense works because it exploits a real gap: the disconnect between what a crash photo shows and what a plaintiff claims to feel. Defense biomechanical experts testify that below a certain Delta-V threshold (typically cited as 5 to 8 mph, depending on the expert), the forces involved are within the range of normal daily activities. Getting on and off a bus. Sitting down hard in a chair. Sneezing.

If you don't have crash-force data at intake, you can't see the MIST defense coming. And by the time you're six months into litigation, you've already spent the money.

"The best defense against a MIST motion isn't a better medical expert. It's knowing the actual Delta-V before you ever sign the client. Half the cases that get destroyed by MIST should never have been taken in the first place." - Senior biomechanical engineer, retained by both plaintiff and defense firms

Conservative PI case management means confronting that reality at the front door. Not at mediation. Not at deposition. At intake.

Building a Scoring Model for Your Docket

The firms running the tightest ships assign an internal score to every intake. It's not formal in the actuarial sense, but it's consistent. Here's a simplified version of what we've seen work.

Liability: clear (3 points), probable (2), disputed (1), adverse (0). Crash severity: Delta-V above 15 mph (3), 10-15 mph (2), 5-10 mph (1), below 5 mph (0). Injury documentation: ER visit within 24 hours with objective findings (3), urgent care within 72 hours (2), PCP visit within a week (1), no treatment for 14+ days (0). Insurance coverage: confirmed BI policy of $100K+ or UM/UIM available (3), $50K-$100K (2), minimum limits (1), unknown or excluded (0).

A score of 9 or above: take the case. A score of 6-8: review with a senior attorney, possibly run a full biomechanical analysis before committing. Below 6: refer out or decline.

This isn't perfect. Nothing at intake is. But it forces a structured conversation instead of a gut call.

The Referral Network as a Revenue Channel

Rejecting 78% of cases doesn't mean those callers vanish. Smart firms have built referral networks that turn rejected intakes into a secondary revenue stream.

A case you decline with a Delta-V of 3 mph and a $15K policy might be exactly right for a solo practitioner who handles high-volume, low-complexity soft tissue files. You refer it out, take a referral fee where ethically permitted under your state bar rules, and maintain a relationship with the caller in case a future incident has real severity behind it.

The AAJ's referral network and state trial lawyer associations (CTLA, FTLA, NYSTLA, among others) formalize this. The point isn't charity. It's resource allocation. Your time-limited demand on a $250K policy-limits case can't wait while you're negotiating a $9,000 BI settlement.

What Changes When You Have Crash Data at Intake

Two years ago, getting a Delta-V estimate required hiring a reconstructionist. That meant $3,000 to $5,000 per file and a two-to-four week turnaround. Nobody was spending that on an intake screening call.

That constraint shaped behavior. Firms took cases based on photos, police reports, and the caller's story. They made liability judgments early and severity judgments late. By the time the crash physics came back (if they ever did), the retainer was signed, the lien letters were sent, and the sunk cost fallacy was in full effect.

Now the physics come first. Three photos, two minutes, and you have a Delta-V range, a damage severity score, and AIS injury probability data before you've opened a file. The methodology behind Silent Witness is validated against NHTSA's crash test database and IIHS severity ratings, which means the numbers hold up under Daubert scrutiny if the case goes to litigation.

That changes intake from an art to a discipline. You're not guessing whether a case can survive a MIST challenge. You know, within a validated range, what forces the occupant experienced. And you make the take-or-reject decision with the same data the defense will eventually use against you.

The Counterargument, and Why It's Mostly Wrong

Some plaintiff attorneys push back on aggressive intake filtering. Their argument: you miss the sleeper case. The low-speed crash that actually caused a legitimate disc herniation in a 62-year-old with pre-existing degenerative changes. The parking lot collision where the angle of impact produced rotational forces well beyond what the bumper damage suggests.

They're right that those cases exist. They're wrong that loose intake criteria are the way to find them.

A scored intake process doesn't automatically reject the 62-year-old's case. It flags it as a score of 5 or 6, routes it to a senior attorney for review, and prompts a biomechanical screening before commitment. The sleeper case gets found precisely because the system creates space for expert judgment on edge cases, instead of burying that judgment under 40 files that should have been declined.

Conservative PI case management isn't about turning away injured people. It's about being honest with yourself (and with them) about which cases you can actually win.

What This Looks Like in Practice

A 14-attorney plaintiff firm in the Southeast ran this model for 18 months. They tracked every intake, every rejection reason, and every outcome on accepted cases. Their numbers: average case value increased 34%. Time to resolution dropped by 11 weeks. Defense MIST motions declined from 41% of litigated cases to 12%, because they stopped taking cases that were vulnerable to that argument in the first place.

The rejection rate held steady at about 78%. The revenue per attorney went up. The burnout went down. The math works because you're concentrating effort where the physics and the medicine and the liability all point in the same direction.
