The committee’s conclusion with respect to medical necessity guidance can be found in Chapter 5. As part of its task, the committee reviewed a variety of definitions of medical necessity identifying key elements, listed here first by individual components solely for comparison purposes, but meant to be combined with other elements. A sampling of complete definitions is given at the end of this appendix.
ELEMENTS OF DEFINITIONS
Significant elements identified in definitions include: who has the authority to decide, what the purpose of an intervention is, what the scope of services would entail, what constitutes acceptable evidence of efficacy, and whether the service has value for potential health gain, is not performed simply for convenience, and is applicable to the individual case.
Authority, Prudent Physician
• Health care services or products that a prudent physician would provide to a patient (AMA, 2005; Harmon, 2011; Maves, 2010)
• “Medically necessary” or “medical necessity” shall mean health care services that a physician, exercising prudent clinical judgment, would provide to a patient (Kaminiski, 2007)
• An intervention is medically necessary if, as recommended by the treating physician and determined by the health plan’s medical director or physician designee, it is … [meets certain criteria for purpose, scope, evidence, and value] (Singer et al., 1999)
Medical Purpose
• A health intervention for the purpose of treating a medical condition—a research project at Stanford further defined a health intervention as an item or service delivered or undertaken primarily to treat (i.e., prevent, diagnose, detect, treat, palliate) a medical condition (i.e., disease; illness; injury; genetic or congenital defect; pregnancy; biological or psychological condition that lies outside the range of normal, age-appropriate human variation) or to maintain or restore functional ability (Singer et al., 1999)
• Health care services or products … for the purpose of preventing, diagnosing, or treating an illness, injury, disease, or its symptoms (AMA, 2005; Harmon, 2011; Maves, 2010)
• Health care … for the purpose of preventing, evaluating, diagnosing, or treating an illness, injury, disease, or its symptoms (Kaminiski, 2007)
• “Medically necessary” is a term for describing a requested service that is reasonably calculated to prevent, diagnose, correct, cure, alleviate, or prevent worsening of conditions in the client that endanger life, cause suffering or pain, result in an illness or infirmity, threaten to cause or aggravate a handicap, or cause physical deformity or malfunction. There is no other equally effective, more conservative, or substantially less costly course of treatment available or suitable for the client requesting the service. For the purpose of this section, “course of treatment” may include mere observation or, where appropriate, no treatment at all (Washington Administrative Code, 2011)
• To prevent the onset or worsening of an illness, condition, or disability; to establish a diagnosis; to provide palliative, curative, or restorative treatment for physical and/or mental health conditions; and/or to assist the individual to achieve or maintain maximum functional capacity in performing daily activities, taking into account both the functional capacity of the individual and those functional capacities that are appropriate for individuals of the same age (Dhillon, 2011; NHeLP, 2011)
• To acquire, retain, and improve the self-help, socialization, and adaptive skills necessary to reside successfully in home and community-based settings (Medicaid per [Ford, 2011])
• Screening and diagnostic services to determine physical or mental defects in recipients under age 21; and health care, treatment, and other measures to correct or ameliorate any defects and chronic conditions discovered1
• For the diagnosis, cure, mitigation, treatment, or prevention of disease or for the purpose of affecting any structure or function of the body2
• Health care provided to correct or diminish the adverse effects of a medical condition or mental illness; to assist an individual in attaining or maintaining an optimal level of health; to diagnose a condition, or prevent a medical condition from occurring3
• For the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member4
• Necessary to prevent, diagnose, correct, or cure conditions in the person that cause acute suffering, endanger life, result in illness or infirmity, interfere with such person’s capacity for normal activity, or threaten some significant handicap5
Scope
• Clinically appropriate in terms of type, frequency, extent, site, and duration (AMA, 2005)
• Clinically appropriate, in terms of type, frequency, extent, site, and duration, and considered effective for the patient’s illness, injury, or disease (Kaminiski, 2007)
• The most appropriate supply or level of service, considering potential benefits and harms to the patient (Singer et al., 1999)
Evidence
• In accordance with generally accepted standards of medical practice (AMA, 2005; Harmon, 2011)
• In accordance with generally accepted standards of medical practice; this means standards that are based on credible scientific evidence published in peer-reviewed medical literature, generally recognized by the
1 Code of Federal Regulations, Title 42, Chapter IV, § 440.40(current as of August 3, 2011).
2 Internal Revenue Tax Code, Title 26, Subtitle A, Chapter 1 § 213(d)(1)(A).
3 Connecticut Agency Regulations, § 17b-134d-63, et seq.
4 Social Security Act, 42 U.S.C. Title XVIII, Section 1862(a)(1)(a).
5 New York State Social Services Law, Title 1, Article 5, § 365 (a).
relevant medical community, or otherwise consistent with the standards set forth in policy issues involving clinical judgment (Kaminiski, 2007)
• Generally accepted standards of medical practice—standards that are based on credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, physician specialty society recommendations, and the views of physicians practicing in relevant clinical areas and any other relevant factors (Kaminiski, 2007)
• In accordance with standards of medical practice that are based on credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, physician specialty society recommendations, and the views of physicians practicing in relevant clinical areas and any other relevant factors (Bocchino, 2010)
• Known to be effective in improving health outcomes. For new interventions, effectiveness is determined by scientific evidence. For existing interventions, effectiveness is determined first by scientific evidence, then by professional standards, then by expert opinion (Singer et al., 1999)
Value
• Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury, or disease (Kaminiski, 2007)
• Cost-effective for this condition compared to alternative interventions, including no intervention; “cost-effective” does not necessarily mean lowest price (Singer et al., 1999)
• That the item or service be the “least costly” alternative course of diagnosis or treatment for which there is adequate “clinical scientific evidence” of its safety and effectiveness6
• There is no other equally effective, more conservative, or substantially less costly course of treatment available or suitable for the client requesting the service; for the purpose of this section, “course of treatment” may include mere observation or, where appropriate, no treatment at all7
• The least costly among similarly effective alternatives, where adequate scientific evidence exists; and efficient in regard to the avoidance of waste and refraining from provision of services that, on the basis of the best available scientific evidence, are not likely to produce benefit8
Not Primarily for Convenience
• Not primarily for the convenience of the patient, treating physician, or other health care provider (AMA, 2005)
• Not primarily for the convenience of the patient, physician, or other health care provider (Kaminiski, 2007)
• Not primarily for the convenience of the patient, physician, or other health care provider (Bocchino, 2011)
• Not primarily for the economic benefit of the health plans and purchasers (AMA, 2005)
Individuality of Application
• Unless the contrary is specified, the term “medical necessity” must refer to what is medically necessary for a particular patient, and hence entails an individual assessment rather than a general determination of what works in the ordinary case. But where, as here, the plan administrator presents sufficient evidence to show that a treatment is not medically necessary in the usual case, it is up to the patient and his or her physician to show that this individual patient is different from the usual in ways that make the treatment medically necessary for him or her (Kaminiski, 2007)

SAMPLE COMPLETE DEFINITIONS
Stanford: Model Contractual Language for Medical Necessity
In the late 1990s, a research team at Stanford developed model contract language, as follows: For contractual purposes, an intervention will be covered if it is an otherwise covered category of service, not specifically excluded, and medically necessary. An intervention may be medically indicated yet not be a covered benefit or meet this contractual definition of medical necessity. A health plan may choose to cover interventions that do not meet this contractual definition of medical necessity (as presented in Table G-1) (Singer et al., 1999).
National Settlement Language
A class action court case clarified that medical necessity decisions must be individualized, also affirming that consideration of cost or comparative effectiveness was acceptable. The associated definition agreed to by more than 900,000 physicians and major insurance companies resulted in a definition in widespread practice in the private market (Kaminiski, 2007):
“Medically Necessary” or “Medical Necessity” shall mean health care services that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury, disease or its symptoms, and that are: a) in accordance with generally accepted standards of medical practice; b) clinically appropriate, in terms of type, frequency, extent, site and duration, and considered effective for the patient’s illness, injury or disease; and c) not primarily for the convenience of the patient, physician or other health care provider, and not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease. For these purposes, “generally accepted standards of medical practice” means standards that are based on credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community or otherwise consistent with the standards set forth in policy issues involving clinical judgment.
Selected Medical Definitions
American Medical Association
The AMA defines “medical necessity” as (AMA, 2005):
Health care services or products that a prudent physician would provide to a patient for the purpose of preventing, diagnosing or treating an illness, injury, disease or its symptoms in a manner that is (a) in accordance with generally accepted standards of medical practice; (b) clinically appropriate in terms of type, frequency, extent, site, and duration; and (c) not primarily for the economic benefit of the health plans and purchasers or for the convenience of the patient, treating physician, or other health care provider.
Medicare
For Medicare, its authorizing legislation defines “medically necessary” rather than “medical necessity”:
Notwithstanding any other provisions of this file, no payment may be made under Part A or Part B for any expenses incurred for items or services, which are not reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member.9
As presented on the Medicare website glossary for patients, “medically necessary” means:
Services or supplies that are needed for the diagnosis or treatment of your medical condition, meet the standards of good medical practice in the local area, and aren’t mainly for the convenience of you or your doctor (CMS, 2011).
9 Social Security Act § 1862 [42 U.S.C. 1395y].

Medicaid
The Medicaid statute does not define “medically necessary” or “medical necessity,” and each state is allowed to develop its own definition (Sindelar, 2002). However, the Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) program’s coverage rules, providing guidance for definitions in pediatric cases, are more inclusive of concepts applicable to the Affordable Care Act (ACA) category of habilitation (O’Connell and Watson, 2001):
Under EPSDT, state Medicaid programs must cover “necessary health care, diagnostic services, treatment and other measures … to correct or ameliorate defects and physical and mental illnesses and conditions.” Services must be covered if they correct, compensate for, or improve a condition, or prevent a condition from worsening—even if the condition cannot be prevented or cured.
TennCare adopted, what was controversial at the time, for its Medicaid definition—“including a requirement that the item or service be the ‘least costly’ alternative course of diagnosis or treatment for which there is adequate ‘clinical scientific evidence’ of its safety and effectiveness” (Blumstein and Sloan, 2000). Such wording is also now seen in other Medicaid-related programs (e.g., see SAGA below).
A recent examination of Medicaid definitions used by Medicaid programs in Connecticut, Massachusetts, New York, and Rhode Island illustrates the diversity of approaches to definition, with variation even within a single state depending on the applicable population (Cohen, 2010).
For Connecticut Medicaid, as administered through its Department of Social Services (DSS)10 (State of Connecticut Department of Social Services):
Health care provided to correct or diminish the adverse effects of a medical condition or mental illness; to assist an individual in attaining or maintaining an optimal level of health; to diagnose a condition or prevent a medical condition or prevent a medical condition from occurring.
Connecticut’s State-Administered General Assistance (SAGA) program (State of Connecticut Department of Social Services, 2009), a cash assistance program for adults without children who are unable to work, uses11:
Health services required to prevent, identify, diagnose, treat, rehabilitate, or ameliorate a health problem or its effects, or to maintain health and functioning, provided such services are:
1. Consistent with generally accepted standards of medical practice;
2. Clinically appropriate in terms of type, frequency, timing, site, and duration;
3. Demonstrated through scientific evidence to be safe and effective and the least costly among similarly effective alternatives, where adequate scientific evidence exists; and
4. Efficient in regard to the avoidance of waste and refraining from provision of services that, on the basis of the best available scientific evidence, are not likely to produce benefit.
For MassHealth, a service, regardless of whether in fee-for-service or managed care arrangements, is considered “medically necessary” if12:
1. It is reasonably calculated to prevent, diagnose, prevent the worsening of, alleviate, correct, or cure conditions in the MassHealth member that endanger life, cause suffering or pain, cause physical deformity or malfunction, threaten to cause or to aggravate a handicap, or result in illness of infirmity; and
2. There is no other comparable, available, and suitable medical service or site of service that is more conservative or less costly to the MassHealth agency. Services that are less costly to the MassHealth agency including health care reasonably known by the provider or identified by the MassHealth agency pursuant to a prior authorization request to be available to the member through a third party.
It is notable that the Medicaid agency is able to impose sanctions on providers, who (1) provide or prescribe a service or (2) admit a member to an inpatient facility when the services or admission are not medically necessary (Kaminiski, 2007), and Massachusetts publishes on its website specific guidelines for medical necessity for 16 services (e.g., bariatric surgery, organ transplant, physical therapy) (Massachusetts Department of Health, 2011).
Fee-for-service and managed care arrangements through Medicaid in New York define medically necessary as13:
Necessary to prevent, diagnose, correct, or cure conditions in the person that cause acute suffering, endanger life, result in illness or infirmity, interfere with such person’s capacity for normal activity, or threaten some significant handicap and which are furnished an eligible person in accordance with state law.
RIte Care, Rhode Island’s Medicaid managed health care program uses the national settlement language referenced above (Kaminiski, 2007).
