You can usually feel it before anyone says it. The answers stop fitting the questions. The IME comes back useful but somehow not enough. The claimant's situation is settling into something permanent, and the file is still being managed like the picture might change next quarter.
That's the moment the file is telling you it has outgrown the IME.
An IME and a Cost of Future Care (CFC) assessment answer fundamentally different questions.
An IME is built around diagnosis and causation: What is the injury? What's its current status? Is it related to the index event? Can the claimant return to work, and on what timeline? It's a snapshot of medical status.
A CFC assessment, by contrast, looks forward - over years, sometimes decades. It maps out what the claimant will actually need to live with their condition: ongoing therapy, medications, equipment, attendant care, home modifications, vocational support, transportation. It quantifies all of it. In catastrophic files, future care costs are routinely the largest single head of damages - often dwarfing pain and suffering, income loss, and past care combined. Anyone who has watched a settlement conversation pivot on a CFC number understands the practical weight of getting it right.
The two documents serve different audiences too. An IME informs adjudication of the claim. A CFC assessment informs resolution of it.
A few patterns we see when a file is ready for a CFC assessment:
The BC catastrophic decision MacEachern v. Rennie is a useful reference. The court awarded $5,275,000 for future care in a TBI case - not because anyone speculated, but because the CFC report laid out specific, justified, costed needs the court could rely on. More recently, the BC Court of Appeal has reinforced that defensible cost of future care evidence will be respected by the courts when it's properly built.
The reverse is also true. Vague, under-supported CFC evidence gets discounted or thrown out. Where a report estimates "approximately 4 hours per week of attendant care for life" without specifying tasks, frequency, source for the hourly rate, or clinical justification, defence counsel will cross-examine it apart. The damages picture collapses with it.
The legal test in BC and across Canada is well-settled: future care must be both medically justified and reasonable. A strong CFC assessment delivers both. That usually means:
Most CFC reports are written by certified rehabilitation registered nurses (CRRNs), occupational therapists, or life care planners with credentialing in cost projection. The credential matters less than the discipline. A CFC that doesn't cite sources for its numbers, doesn't separate injury-related from non-related needs, or doesn't anchor recommendations to clinical input is going to struggle on cross-examination.
Commissioning a CFC at the right point does a few things an IME alone can't. It gives the adjuster and counsel a defensible number rather than a guess. It surfaces care needs that may already be inadequately covered - sometimes prompting interim adjustments before settlement. It reduces the chance of the file reopening post-settlement because something was missed. And it gives the claimant clarity on what their long-term needs actually look like, which tends to make resolution easier for everyone.
Timing matters in the other direction too. Commissioning a CFC too early - before medical plateau - produces a report that gets superseded by recovery and undermines its own usefulness. The window most defensible CFC reports are written in is post-plateau, pre-mediation: late enough that the clinical picture is stable, early enough that the number actually drives the resolution conversation.
If the file is asking "what does this person need to live with this injury?" - the IME has done its job, and it's time for the CFC. Done well, it's the document that lets the file actually close. Done poorly or commissioned at the wrong moment, it becomes another expense without resolving the question it was supposed to answer. Knowing when to call for one is half the skill.
