Howell Update: Another Victory for Defendants

Last week the California Court of Appeal issued another huge victory to defendants by extending the reach of the landmark California Supreme Court Howell v. Hamilton Meats case to include future medical benefits under the Patient Protection and Affordable Healthcare Act (“ACA”).  In 2011, Howell sent shock waves through the insurance industry when the Court examined the “billed vs. paid” rule and concluded an injured plaintiff is limited to recovering the discounted amount private health insurance pays on their behalf for as past medical damages, not the inflated amount medical providers bill health insurance companies for their services.  (Howell v. Hamilton Meats & Provisions, Inc. (2011) 52 Cal.4th 541.)  In 2013, the California Court of Appeal extended Howell‘s “paid” rule to apply to future medical expenses and noneconomic damages.  (Cornenbaum v. Lampkin (2013) 215 Cal.App.4th 1308, 1331-1333.)
