In Audish v. Macias (2024) 102 Cal.App.5th 740, the California Court of Appeal decided a key issue concerning the admissibility of a plaintiff’s future Medicare eligibility in calculating damages for future medical expense claims. This decision has significant implications for how future medical expenses are assessed in tort cases, particularly in the cost and construction of life care plans.

Case Background

The case arose from a motor vehicle accident involving Plaintiff David Audish and Defendant David Macias. Id. at 745. Both parties were found negligent: Macias for making an illegal left turn and Audish for speeding. Id. The jury determined that each party was 50% responsible for the incident and awarded Audish $65,699.50 in damages, which included $32,790.56 for future medical expenses. Id.

Prior to trial, Audish filed a motion in limine seeking to exclude any evidence suggesting he had, or would have, medical insurance. Id. at 746. The Trial Court partially granted and partially denied this motion, allowing expert witnesses, with proper foundation, to testify about the reasonable value of medical care based on rates insurers pay for medical treatments. Id.

During the trial, a nurse and life care planner testified on behalf of Audish, presenting a life care plan estimating Audish’s future medical costs at $1,417,146. Id. at 746-47. Her calculations were based on average amounts charged by medical providers. Id. On cross-examination, she acknowledged that her estimates did not consider the negotiated and often discounted amounts insurers actually pay providers for the treatments or the amounts Medicare would pay once Audish became eligible at age 65. Id. This testimony highlighted the significant gap between the amounts health care providers bill and actual payments made by insurance providers.

Audish appealed, arguing, in part, that the Trial Court erred by admitting evidence of his potential Medicare eligibility at age 65. Id. at 747-48. He argued that this admission violated the collateral source rule, which generally prohibits defendants from introducing evidence that a plaintiff has received compensation from sources independent of the defendant, such as insurance, to reduce the damages owed. Id.

Court of Appeal’s Analysis

The Court of Appeal upheld the Trial Court’s decision to admit evidence of future Medicare eligibility and the anticipated amounts Medicare might pay for future medical services, reasoning that it was relevant to determining the reasonable value of future medical care and did not violate the collateral source rule. Id. at 749-50. The ruling aligns with several key California precedents:

  • Howell v. Hamilton Meats & Provisions, Inc. (2011) 52 Cal.4th 541 — Established that a plaintiff can only recover the amounts actually paid for medical services, rather than the amounts billed, emphasizing that the collateral source rule does not apply to expenses never incurred by the plaintiff. 
  • Corenbaum v. Lampkin (2013) 215 Cal.App.4th 1308 — Extended Howell to future medical damages, holding that evidence of the full amount billed for past medical services is irrelevant to determining the reasonable value of future care.
  • Cuevas v. Contra Costa County (2017) 11 Cal.App.5th 163 — Allowed consideration of future benefits from Medi-Cal or the Affordable Care Act when evaluating future medical damages.
  • Stokes v. Muschinske (2019) 34 Cal.App.5th 45 — Permitted references to a plaintiff’s past medical insurer (Kaiser) and his future eligibility for Medicare and Social Security benefits during cross-examination of the plaintiff’s life care planner, finding these references helpful and necessary to the jury’s understanding of the plaintiff’s past treatment and the calculation of future reasonable medical expenses.

Id. at 748-51.

Implications for Life Care Plans and Future Litigation

One of the most significant consequences of Audish is its potential to substantially reduce the cost of life care plans in personal injury litigation, resulting in lower overall damage awards for future medical care. Traditionally, plaintiffs’ life care planners base their projections on the full billed rates for medical services, often leading to windfall damage awards for plaintiffs based on artificially inflated estimates of future medical costs. By allowing evidence of future eligibility for health insurance, such as Medicare, and discounted insurance rates, the Court’s ruling provides a mechanism for defendants to challenge excessive life care plan costs and ensure that damage awards mirror the more realistic economic losses a plaintiff may incur.

Life care plans will now need to more accurately represent what healthcare providers are likely to be paid — not just what they bill. Life care planners will be forced to confront the reality of insurance discounts and benefits, leading to more accurate and realistic projections of future costs. This shift could also reduce litigation costs. More accurate life care plans may facilitate earlier settlements and discourage prolonged disputes over inflated damages, as both parties may have clearer expectations regarding damages.  

Ultimately, Audish sets a powerful precedent that damage awards for future medical expenses should be grounded in real-world costs. This decision moves the legal system closer to ensuring that plaintiffs are compensated for actual losses rather than speculative or inflated projections in personal injury cases.
