How Future Medical Costs Are Calculated in a Personal Injury Case

Future medical costs in a personal injury case are determined by identifying each type of care that the claimant is likely to need. This involves multiplying the unit cost of each item by its expected frequency and the number of years it will be required. The calculation is then adjusted for medical inflation, and the final figure is discounted to present value. A life care planner or a physician life care planner typically carries out this process. The resulting total serves as a foundational figure for the economic damages portion of a demand, mediation, or trial.

What Are Future Medical Costs in a Personal Injury Case?

Future medical costs are the projected expense of care a claimant is expected to need after the case resolves, as distinct from medical bills already incurred. They are typically documented in a life care plan or a medical cost assessment and are included in the economic damages a firm can claim.

Items that typically qualify as future medical costs include:

Future surgeries and procedures
Ongoing physician follow-up and specialist visits
Physical, occupational, or other therapy
Prescription medications
Durable medical equipment (DME), such as wheelchairs, braces, or prosthetics
Home modifications required by the injury
Attendant or personal care services
Diagnostic imaging and monitoring

The Formula: How Future Medical Costs Are Calculated

Future medical costs are calculated in six steps, moving from what the record documents to a single lifetime figure or range:

Identify every future care item documented in the medical records: A life care planner reviews the full record and lists each treatment, medication, service, or piece of equipment that a treating physician has indicated the claimant will need going forward.
Assign a unit cost to each item: Every item gets priced individually, such as a single physical therapy session, a single MRI, a month of a specific medication, rather than being folded into a lump estimate.
Set the frequency (per year) and duration (number of years): Each item is assigned how often it recurs annually and how many years it continues, which may be a fixed term, a period tied to a milestone like age 65, or the claimant's remaining life expectancy.
Apply category-specific medical inflation: Because different categories of care inflate at different rates, each item's future-year cost is adjusted using the medical inflation rate appropriate to that category rather than a single blended number.
Discount to present value: Future-year costs are converted into a present-day lump sum using a discount rate, reflecting the return the claimant could reasonably earn investing that sum today.
Total into a lifetime figure or range: Every item's present-value cost is summed into a single lifetime total, or a range when input assumptions (like duration) reasonably vary.

A simplified worked example, using illustrative figures rather than any real case, shows how the pieces combine:

Care Item	Unit Cost	Frequency	Duration	Lifetime Total (Illustrative)
Physical therapy	$150/session	2x/week	2 years	≈ $31,200
Orthopedic follow-up	$300/visit	4x/year	10 years	≈ $12,000
Pain management medication	$120/month	12x/year	Life expectancy (30 yrs)	≈ $43,200

These figures are illustrative only, before medical inflation and present-value discounting are layered in; an actual life care plan applies to every line item before totaling the plan.

Where the Cost Data Comes From

Unit costs are not estimated; they come from documented pricing sources and are cross-checked against the geographic market where the claimant will actually receive care. Common sources include:

CPT-code-level pricing for specific procedures and services
Geographic cost adjustment, since the same procedure can cost significantly more or less, depending on the region
Medicare fee schedules as a pricing reference point
Commercial charge databases reflecting what providers actually bill
Actual billed amounts are already reflected in the claimant's own medical records

Geography matters because provider charges vary substantially by market. A projection based on national averages rather than the claimant's actual geographic market can materially overstate or understate the real cost of future care.

How Life Expectancy and Duration Are Determined

Duration for most future care items is set using standard actuarial life tables, most commonly the U.S. period life tables published by the CDC's National Center for Health Statistics (NCHS), which estimate remaining life expectancy by current age and sex.

Certain catastrophic injuries require the use of condition-specific tables instead of standard population tables. This is because injuries such as spinal cord injuries or severe traumatic brain injuries (TBIs) can significantly impact life expectancy in ways that general population data does not reflect.

Additionally, not every item is intended to last for the claimant's full life expectancy. Some items are assigned a fixed duration, such as 5 years of physical therapy, while others are tied to specific milestones, such as reaching age 65, as documented by the treating physician.

Medical Inflation and Present Value, Explained

Medical Inflation

Medical inflation is the rate at which the cost of care rises year over year, and it varies across categories.

The Bureau of Labor Statistics reported the medical care index up 1.7 percent over the 12 months ending July 2026, and the BLS Medical Care fact sheet details how the agency measures price changes separately across categories such as physicians' services, hospital services, and prescription drugs. A life care planner applies the inflation rate relevant to each item's category, not a single flat number across the whole plan.

For example, a physical therapy session priced at $150 today, inflated at a category-specific rate of roughly 3 percent annually, would run approximately $174 by year five of the plan, not $150.

Present Value

Present value is the lump sum today that, invested at a reasonable rate of return, would be sufficient to cover a stream of future costs as they come due.

In plain terms, the discount rate represents the return the claimant could reasonably expect to earn by investing a settlement or verdict today, rather than receiving each year's medical costs individually as they occur.

For example, a future care item costing $2,000 a year for 10 years, discounted at a 3 percent rate, has a present value of roughly $17,000, not the simple $20,000 sum of ten $2,000 payments, because a portion of that total is expected to be earned through investment return rather than paid out of the original settlement.

Medical Cost Projection vs. Life Care Plan: What's the Difference?

A medical cost projection and a life care plan both project future medical expenses, but they differ in scope, depth, and purpose.

	Medical Cost Projection	Life Care Plan
Scope	Future medical expenses only	Future medical expenses plus broader life-impact categories (e.g., vocational, household services, where applicable)
Depth	Calibrated for early-stage evaluation and negotiation	Comprehensive, line-by-line analysis across the claimant's projected lifetime
Turnaround	Typically faster (e.g., a few weeks)	Typically longer (e.g., several weeks), given its comprehensive scope
Typical Case Type	Early case evaluation mediation, lower-limit policy cases	Cases likely to proceed to trial or requiring the fullest evidentiary support
Built for Testimony	Designed to stand as material evidence, not always built around live testimony	Designed with the authoring expert available to testify

Who Prepares Future Medical Cost Projections?

Several credentialed roles can prepare or contribute to a future medical cost projection, and firms should know which one is behind a given document:

Certified Life Care Planner (CLCP): A professional credentialed through the International Commission on Health Care Certification (ICHCC), the only accredited certifying body in the field of life care planning.
Physician life care planner: A board-certified physician who authors life care plans, often in adherence to standards such as those of the American Academy of Physician Life Care Planners.
Nurse life care planner: A registered nurse with specialized life care planning training and credentials.
Forensic economist: An economist who applies present-value and inflation methodology to the life care planner's projected costs.
Treating physician: The claimant's own physician, whose documented recommendations in the medical record are the factual foundation on which every projection is built.

Naming the credentialing bodies behind these roles matters for defensibility: the ICHCC requires a minimum 120-hour ICHCC-approved training program and a peer-reviewed sample life care plan for CLCP certification, renewed every five years, and the International Academy of Life Care Planners (IALCP), a section of the International Association of Rehabilitation Professionals, publishes its own standards of practice for the field.

The American Academy of Physician Life Care Planners (AAPLCP) sets a parallel standard specifically for physician-authored plans.

What Makes a Future Medical Cost Projection Defensible

A defensible projection is one where every item traces back to the medical record, the methodology is published rather than proprietary and hidden, the author is qualified, and the assumptions behind frequency, duration, and cost are stated plainly rather than buried.

That standard is not just best practice; it tracks the actual evidentiary bar. Federal Rule of Evidence 702, amended effective December 1, 2023, requires the proponent of expert testimony to establish, by a preponderance of the evidence, that the testimony reflects a reliable application of a reliable method to the facts of the case, not simply that the expert holds a credential.

Defense attacks on future medical cost projections tend to cluster around a few recurring arguments:

Speculative items: A recommended treatment that no treating physician actually documented.
Unsupported frequency: A projected frequency of care not tied to what the record or a treating physician specifies.
Inflated unit cost: Pricing pulled from national averages rather than the claimant's actual geographic market.
No treating-physician support: A future item that exists in the plan but nowhere in the underlying medical record.

Every one of these attacks targets the same weakness: a gap between what the projection claims and what the record actually documents. Closing that gap is the entire discipline of building a defensible plan.

How Future Medical Costs Affect Settlement Value

Future medical costs are often the largest component of economic damages in a catastrophic personal injury case and typically serve as the basis of a demand for compensation. A well-supported projection provides a firm basis for negotiations, rather than relying on estimates based solely on intuition.

Future medical costs also impact other aspects of case resolution. They can play a role in lien negotiations, as a portion of a settlement may need to cover the claimant’s ongoing care needs. Additionally, they can intersect with Medicare Set-Aside considerations in cases involving Medicare beneficiaries. However, this information does not replace the need for case-specific legal and financial advice regarding the structuring of a particular settlement.

Frequently Asked Questions

How far into the future can medical costs be projected?
Medical costs can be projected for a fixed number of years or across a claimant's full remaining life expectancy, depending on the injury and the treating physician's documented recommendations. Catastrophic injuries are more likely to involve lifetime projections than a soft-tissue injury with a defined recovery period.

Do future medical expenses have to be reduced to present value?
In most jurisdictions, yes, future damages awarded as a lump sum are typically discounted to present value, since the claimant receives the money today rather than as it is spent over future years. The specific approach can vary by jurisdiction, so case-specific legal guidance should be obtained to confirm local requirements.

What's the difference between a medical cost projection and a life care plan?
A medical cost projection covers future medical expenses only and is typically calibrated for early case evaluation or negotiation. A life care plan is a more comprehensive, line-by-line document that covers the claimant's full projected care needs, generally prepared for cases likely to proceed to trial.

Who is qualified to testify about future medical costs?
Testimony typically comes from the credentialed professional who authored the projection, often a physician life care planner or Certified Life Care Planner (CLCP), sometimes alongside a forensic economist addressing the inflation and present-value calculations specifically.

How long does a life care plan take to produce?
Turnaround varies by provider and case complexity, but a comprehensive life care plan typically takes several weeks, given the depth of record review involved. In contrast, a more narrowly scoped medical cost assessment can typically be produced faster. Expedited timelines are often available for time-sensitive matters.

Can future medical costs be estimated from medical records alone?
An initial estimate can be developed from the documented diagnoses, treatment history, and future care recommendations already in the medical records. A full, litigation-ready projection typically still requires a credentialed life care planner to apply pricing, inflation, and present-value methodology on top of that record review.
