Health insurance companies will only provide coverage for services that they define as medically necessary. This means that, regardless of what a patient or healthcare provider believes is medically necessary, the insurance company's definition of medical necessity will determine whether a procedure is covered. Medicare, for example, 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. This definition is used by other insurance companies, but they may also set their own criteria.

What You'll Learn

Medicare's definition of 'medical necessity'
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". This definition applies to services provided under Medicare Part B (Medical Insurance).
Medicare Advantage plans, also known as non-Medicare plans, set their own prior authorisation and medical necessity guidelines. However, their medical necessity requirements cannot be more restrictive than those used by Original Medicare.
Medicare coverage is limited to items and services that are reasonable and necessary for the diagnosis or treatment of an illness or injury. This coverage must also fall within the scope of a Medicare benefit category. National coverage determinations (NCDs) are made through an evidence-based process, with opportunities for public participation. In some cases, the Centers for Medicare & Medicaid Services' (CMS) research is supplemented by an outside technology assessment and/or consultation with the Medicare Evidence Development & Coverage Advisory Committee (MEDCAC).
The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 amended portions of the NCD development process, with an effective date of January 1, 2004. The CMS website outlines the process and timeline for NCD requests, including those that require an external technology assessment or MEDCAC review. The CMS website also outlines an expedited administrative process to remove certain NCDs older than 10 years since their most recent review.

Private insurers' criteria
Private insurance companies define medical necessity in their own way, and these definitions are often used to determine the coverage of health insurance plans. While Medicare has a set definition of "medically necessary", private insurers can set their own criteria, which may or may not mirror Medicare's definition.
In the case of Cigna Healthcare, they emphasize that treatment decisions should be clinically based and patient-centered. They consider the individual's needs, clinical and environmental factors, and personal values. This approach ensures that their Medical Necessity Criteria are aligned with the specific circumstances of each patient.
It is worth noting that private insurers' criteria for medical necessity must also comply with state and federal benefit mandates. This means that while they can set their own criteria, they are still subject to certain regulations and may need to provide coverage for essential health benefits as defined by the Affordable Care Act. As a result, there can be variations in the specific services covered under each essential health benefit from state to state.
Ultimately, regardless of the private insurer's criteria, no plan will cover care that is not considered medically necessary. Procedures that are deemed cosmetic, experimental, or unproven are typically not covered by health insurance plans. It is always advisable to review your benefits handbook or contact your health plan's customer service representative to understand what is covered under your specific insurance plan.

Preventative care
From a healthcare provider's perspective, medical necessity refers to any service or product prescribed to prevent, diagnose, or treat a medical condition. These services adhere to established medical standards and guidelines. Preventative care falls under this category as it helps maintain health, identify potential issues, and reduce the risk of future illnesses or injuries.
However, when it comes to insurance coverage, the definition of "medical necessity" may vary. Insurance providers use this term to describe the coverage they offer and determine what services they will pay for. In the context of preventative care, insurance companies may consider certain aspects to define medical necessity. These considerations can include the patient's clinical needs, environmental factors, and personal values. Additionally, insurance companies often rely on guidelines and decisions made by reputable organizations, such as the United States Preventive Services Task Force, to help establish their criteria for medical necessity.
It is worth noting that insurance coverage for preventative care can vary depending on the specific plan and applicable laws. Some insurance plans may fully cover certain preventative services, such as shots and screening tests, when provided by in-network doctors or providers. On the other hand, there might be instances where insurance companies deny coverage for preventative care services that healthcare providers deem medically necessary. This discrepancy can occur due to differences in the interpretation of medical necessity between healthcare providers and insurance companies.
To avoid unexpected costs, it is essential to review your insurance plan's coverage details, understand its definition of "medical necessity," and be aware of any pre-authorization or step therapy requirements. By staying informed about your insurance plan's provisions and limitations, you can make more informed decisions regarding your preventative care and overall health management.

Marijuana's classification
Health insurance companies provide coverage only for health-related services that they define or determine to be medically necessary. Medicare, for example, 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”. Most health plans will not pay for healthcare services that they deem to be not medically necessary.
As a depressant, marijuana slows down messages between the body and the brain, calming nerves, relaxing muscles, and lowering inhibitions. It can be used to treat anxiety, sleep problems, and muscle spasms. However, it can also lead to short-term memory loss and increased anxiety with prolonged use.
Marijuana's stimulant properties can increase alertness, attention, and energy. However, abusing marijuana for its stimulant effects can lead to addiction, increased anxiety, and paranoia.
As a hallucinogen, marijuana can cause profound distortions in a person's perception of reality, including hallucinations, delusions, and a loss of sense of personal identity. These effects are generally temporary but can be particularly harmful to individuals with schizophrenia or other mental illnesses.
The effects of marijuana vary from person to person, and it is important to note that it can have both positive and negative impacts on mental health. Some people use marijuana to enhance their mood and treat symptoms of depression and anxiety. However, it can also cause or exacerbate these conditions in some individuals.

Cosmetic procedures
The distinction between cosmetic and medically necessary procedures can be blurry, and insurance companies will often require proof that a procedure is not solely for aesthetic reasons before they agree to cover it. For example, a patient may wish to have a skin tag removed from their armpit because it is painful and irritated by clothing, but an insurance company may deem this cosmetic and refuse to cover the procedure.
It is important to understand the terms of your insurance policy and whether it covers cosmetic procedures, as well as to be aware of any negative side effects of the procedure. If you are considering a cosmetic procedure, you should contact your insurance provider to understand your policy's terms and conditions regarding such surgeries. You should also research similar cases and look for examples of people who have successfully obtained insurance coverage for similar procedures.
If a cosmetic procedure is deemed medically necessary, it may be covered by insurance. However, there are usually still out-of-pocket expenses involved, such as deductibles, co-pays, and co-insurance. It is important to be well-prepared and to work closely with your surgeon and insurance provider to determine whether a procedure will be covered.
