What does “medically necessary”, “medical necessity” & IMR mean?

Medical Necessity 

A service is “medically necessary” or a “medical necessity” when it is reasonable and necessary to protect life, to prevent significant illness or significant disability, or to alleviate severe pain.  ^{(2014 ACA Sample EOC Page 166) * CIGNA’s Definition  * CA WIC  §14059.5}

Medically Necessary shall mean health care services that a Physician, exercising professional 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:

In accordance with generally accepted standards of medical practice, ^{Illinois Dept of Insurance Definition}

The Five Dimensions of the Medical Necessity Definition

• The contractual scope of coverage: whether proposed treatment is explicitly included or excluded in the health plan contract
• Whether the proposed treatment is consistent with professional standards of practice
• Patient safety and setting of the treatment
• Whether the treatment is medical in nature or for the convenience of the health professional or patient and family
• Treatment cost     samhsa.gov

most definitions incorporate the principle of providing services which are “reasonable and necessary” or “appropriate” in light of clinical standards of practice

Medicare defines “medical necessity” as services or items reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member. ^{Glossary Meeicare.Gov}

Utilization Review

Medicare coverage  Knee &Hip Replacement Requirements
—  #Grievances Medicare”

• Does Medicare cover knee replacement surgery? Fortune.com 
• Back & Forth conversation with a website visitor on Medical Necessity requirements from Medicare for Knee Replacement
• Lower Extremity Major Joint Replacement (Hip and Knee)  Medicare Requirements  CMS.Gov
• DOCUMENT MEDICAL NECESSITY TO AVOID DENIAL OF CLAIMS
  • CMS recognizes that joint replacement surgery is reserved for patients whose symptoms have not responded to other treatments. To avoid denial of claims for major joint replacement surgery, the medical records should contain enough detailed information to support the determination that major joint replacement surgery was reasonable and necessary for the patient. Progress notes should consist of more than just conclusive statements. Therefore, the medical record of the joint replacement surgical patient must specifically document a complete description of the patient’s historical and clinical findings. Both physicians and hospitals are responsible for ensuring a complete and accurate record.
• Joint Replacement Model extended for 3 years
• Unnecessary health care (overutilization, overuse, or overtreatment) is health care provided with a higher volume or cost than is appropriate.[1] In the United States, where health care costs are the highest as a percentage of GDP, overuse was the predominant factor in its expense, accounting for about a third of its health care spending ($750 billion out of $2.6 trillion) in 2012.[2]
• Factors that drive overuse include paying health professionals more to do more (fee-for-service), defensive medicine to protect against litigiousness, and insulation from price sensitivity in instances where the consumer is not the payer—the patient receives goods and services but insurance pays for them (whether public insurance, private, or both).[3] Such factors leave many actors in the system (doctors, patients, pharmaceutical companies, device manufacturers) with inadequate incentive to restrain health care prices or overuse.[1][4] This drives payers, such as national health insurance systems or the U.S. Centers for Medicare and Medicaid Services, to focus on medical necessity as a condition for payment. However, the threshold between necessity and lack thereof can often be subjective.
• Overtreatment, in the strict sense, may refer to unnecessary medical interventions, including treatment of a self-limited condition (overdiagnosis) or to extensive treatment for a condition that requires only limited treatment.
• It is economically linked with overmedicalization. ^{wikipedia.org/Unnecessary_health_care}

  • The most common reason for total knee replacement surgery is arthritis of the knee joint. Types of arthritis include osteoarthritis, rheumatoid arthritis and traumatic arthritis (arthritis which occurs as a result of injury). This arthritis causes a severe limitation in the activities of daily living, including difficulty with walking, squatting, and climbing stairs. Pain is typically most severe with activity and patients often have difficulty getting mobilized when seated for a long time. Other findings include chronic knee inflammation or swelling not relieved by rest, knee stiffness, lack of pain relief after taking non-steroidal anti-inflammatory medications and failure to achieve symptom improvement with other conservative therapies such as steroid injections and physical therapy. Osteonecrosis and malignancy are additional reasons to proceed with total knee replacement surgery. The goal of total knee replacement surgery is to relieve pain and improve or increase patient function.
• Total knee replacement surgery will be considered medically necessary when one or more of the following criteria are met:
  • Unsuccessful history of appropriate conservative therapy (non-surgical medical management) that is clearly addressed in the pre procedure medical record. Non surgical medical management is usually implemented for 3 months or more to assess effectiveness. Conservative treatment as clinically appropriate for the patient’s current episode of care typically include one or more of the following:
  • anti inflammatory medications,
  • analgesics,
  • flexibility and muscle strengthening exercises,
  • supervised physical therapy [Activities of daily living (ADLs) diminished despite completing a plan of care],
  • activity restrictions as is reasonable,
  • assistive device use,
  • weight reduction as appropriate, therapeutic injections into the knee as appropriate.
• Documentation Requirements
  • The medical record must contain documentation that fully supports the medical necessity and justification of the procedure performed.

  • Since my orthopedic surgeon has indicated that I need Total Knee Replacement, how can I over-ride the Medicare requirement that I have Cortisone Injections before I can have the surgery?
  • All my extensive research shows that Cortisone is very damaging to skin, bones and surrounding tissue, just prolongs the damage to my knee, and means that I will be that much older perhaps necessitating a longer recovery.
  • I am also an athlete and I am unable to participate in my numerous sports so waiting for Total Knee Replacement means it will be much harder to re-gain my fitness.
  • Cortisone Injections are just another cost for Medicare (and me) when TKR will be the end result!

• I don’t have a grievance yet–so will see how my Appeal for a TKR now goes, since I’ve met the qualifications of “conservative treatments” over the course of the last 2-3 years!!!
  • We need to use the exact proper terms.
    • Grievance—A complaint about the way your Medicare health plan or Medicare drug plan is giving care. For example, you may file a grievance if you have a problem calling the plan or if you’re unhappy with the way a staff person at the plan has behaved towards you. However, if you have a complaint about a plan’s refusal to cover a service, supply, or prescription, you file an appeal.
    • Appeal—An appeal is the action you can take if you disagree with a coverage or payment decision made by Medicare, your Medicare health plan, or your Medicare Prescription Drug Plan. You can appeal if Medicare or your plan denies one of these:
      ■ Your request for a health care service, supply, item, or prescription drug that you think you should be able to get
      ■ Your request for payment for a health care service, supply, item, or prescription drug you already got
      ■ Your request to change the amount you must pay for a health care service, supply, item or prescription drug
      You can also appeal if Medicare or your plan stops providing or paying for all or part of a health care service, supply, item, or prescription drug you think you still need.

• CMS recognizes that joint replacement surgery is reserved for patients whose symptoms have not responded to conservative treatments.
  • Pre-surgical physical therapy progress notes are important in demonstrating how the patient has progressively worsened over a period of time. Noting that the patient has “failed conservative therapies” in the history and physical is a conclusive statement and should be supported by other specific, objective information in the patient’s medical record.  cgsmedicare.com/total_knee_fact_sheet
