What is Reasonable and Necessary?

The legal standard requiring that medical treatment and expenses be both medically appropriate for the condition and charged at a fair rate to be recoverable in a personal injury claim.

Understanding Reasonable and Necessary

Insurance companies and defendants often challenge medical expenses by arguing they were not reasonable and necessary. "Reasonable" refers to the cost being in line with what other providers charge in the area for similar services. "Necessary" means the treatment was medically required given the patient's condition. Excessive or unrelated treatment may be excluded from damages.

  • 3Expert testifying that physical therapy was medically necessary for recovery
