Insulin Infusion Pump

Policy Number: MP-046

Latest Review Date: March 2023

Category:  Durable Medical Equipment                               


Insulin infusion pumps(E0784/A9274) may be considered medically necessary when all the following prerequisites are met and are clearly documented in the individual's medical record.

  1. Individual must have had the diagnosis of and been treated for diabetes for 6 months or greater;
  2. Individual/caregiver has demonstrated ability and willingness to monitor blood glucose levels more than 4 times per day;
  3. Individual/caregiver is motivated to achieve and maintain improved glycemic control;
  4. Individual/caregiver is capable physically and intellectually to operate pump;
  5. Individual/caregiver demonstrates compliance with dietary and insulin regimen;
  6. Completion of a diabetes self-management education program by the individual or caregiver.

In addition to the above prerequisites, the individual must also meet one or more of the following indications:

  1. Two glycosylated hemoglobin (HbA1c) > 7.0% (where upper range of normal is less than 6.05%; for other assays, 1% over upper range of normal) within a 120-day time span;
  2. History of severe glycemic excursions commonly associated with brittle diabetes, such as hypoglycemic unawareness, nocturnal hypoglycemia, extreme insulin sensitivity and/or very low insulin requirements;
  3. Wide fluctuations in blood glucose before mealtimes (e.g., pre-prandial blood glucose level commonly exceeds 140 mg/dL);
  4. Dawn phenomenon with fasting blood glucose level often exceeds 200 mg/dL;
  5. Day-to-day variations in work schedule, mealtime, and/or activity level, which confound the degree of regimentation required to self-manage glycemia with multiple insulin injections;
  6. Preconception or pregnancy with a history of suboptimal glycemic control;
  7. Suboptimal glycemic and metabolic control post-renal transplant.

One insulin infusion pump (E0784) is allowed every 4 years.

Back up insulin infusion pumps are considered not medically necessary.

Replacement or upgrade of existing, properly functioning equipment, even if warranty has expired, is considered not medically necessary.

Replacement of a non-functioning insulin infusion pump with a subsequent pump may be considered medically necessary for coverage.  If the patient has demonstrated compliance with the current pump, the above medical criteria do not have to be met for the pump to be replaced.

The V-Go™ Disposable Insulin Delivery Device is considered investigational.

Coverage for non-medical items, even when the items may be used to serve a medical purpose, such as smart devices (smart phones, tablets, personal computers, etc.) are non-covered. This includes smart devices used in conjunction with Insulin pumps/Continuous Glucose Monitors.

For Medtronic’s MiniMed 630G/670G/770G ,Tandem T:slim X2® with CONTROL-IQ or BASAL-IQ technology, or Omnipod 5®, refer to coverage for Artificial Pancreas Device Systems.


External insulin pumps are designed to provide continuous subcutaneous insulin infusion in patients with diabetes mellitus. The external insulin pump is a programmable battery-powered mechanical syringe/reservoir regulated by a miniature computer that delivers a steady, continuous (“basal”) amount of insulin and releases a bolus dose at meals or smaller amounts at programmed times. Pumps may be combined or integrated with standard finger-stick glucose monitoring system. Frequent monitoring of the blood glucose (e.g., four times per day) is essential to ensure appropriate delivery of insulin dosage. The pump is worn continuously day and night. However, there is a disconnect feature on the infusion set which allows the diabetic person to safely disconnect from the pump for short periods of time.

Types of Diabetes

Type 1 Diabetes:

Previously called insulin-dependent diabetes mellitus (IDDM) or juvenile onset diabetes. Type 1 diabetes develops when the body's immune system destroys pancreatic beta cells, the only cells in the body that make the hormone insulin that regulates blood glucose. This form of diabetes usually strikes children and young adults, although disease onset can occur at any age. Type 1 diabetes may account for 5% to 10% of all diagnosed cases of diabetes. Risk factors for Type 1 diabetes may include autoimmune, genetic, and environmental factors.

Type 2 Diabetes:

Previously called non-insulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes. It usually begins as insulin resistance, a disorder in which the cells do not use insulin properly. Type 2 diabetes is associated with older age, obesity, family history of diabetes, history of gestational diabetes, impaired glucose metabolism, physical inactivity, and race/ethnicity. Type 2 diabetes is increasingly being diagnosed in children and adolescents.

Gestational diabetes:

Gestational diabetes is a form of glucose intolerance that is diagnosed in some women during pregnancy. It is more common among obese women and women with a family history of diabetes. During pregnancy, gestational diabetes requires treatment to normalize maternal blood glucose levels to avoid complications in the infant.

This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.

This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.

The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.

As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.

The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:

1. The technology must have final approval from the appropriate government regulatory bodies;

2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;

3. The technology must improve the net health outcome;

4. The technology must be as beneficial as any established alternatives;

5. The improvement must be attainable outside the investigational setting.

Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:

1. In accordance with generally accepted standards of medical practice; and

2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and

3. Not primarily for the convenience of the patient, physician or other health care provider; and

4. 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.
