Here is a list of most common ‘medically necessary’ surgeries and their average cost in the States.

What is considered ‘Medically Necessary’?

Medicare defines ‘medically necessary’ as “Services or supplies that are needed to diagnose or treat your medical condition and that meet accepted standards of medical practice.” It is a term used in the healthcare insurance industry to describe the coverage offered by a health plan. Every health insurance company has its own policies to identify what is a medically necessary service. Typically, these services are:

  • Provided for the diagnosis, treatment, cure, or relief of a health condition, illness, injury, or disease
  • Necessary for and appropriate to the diagnosis, treatment, cure, or relief of a health condition, illness, injury, or disease
  • Within the generally accepted standards of medical care in the community
  • Not solely for the convenience of the insured, the insured’s family, or the provider

Elective vs Necessary Surgeries

An elective surgery is a procedure that the patient can choose to have or not have. It may be medically necessary or it may not be. This classification depends on the patient’s medical professional, their insurance company’s policies, or in the case of Medicare or Medicaid, on the federal government. Even if a procedure is elective, most health insurance plans will pay for them, as long as they are deemed necessary.
