Clinical UM Guideline

This document addresses the use of external insulin pumps, which provide subcutaneous insulin infusion to treat diabetes mellitus.

Note: Some external insulin pump devices come equipped with the capacity to be combined with continuous interstitial glucose monitor (CGM) devices to create automated insulin delivery systems. Devices with such features may be used as stand-alone insulin pumps or as combined systems, depending upon an individual’s need.

• CG-SURG-79 Implantable Infusion Pumps

Medically Necessary:

External insulin pumps (either disposable or durable) are considered medically necessary when the following criteria are met:

1. The individual has documented diabetes mellitus (any type); and
2. The individual or caregiver(s) has completed a comprehensive diabetes education program; and
3. Both of the following criteria are met:
   1. Insulin injections are required multiple times daily; and
   2. Multiple blood glucose tests are required daily or a continuous glucose monitor is being used.

Refills for medically necessary disposable external insulin pumps are considered medically necessary.

Continued use of an external insulin pump (including for individuals who used a continuous insulin infusion pump prior to enrollment with this plan) is considered medically necessary when the device has resulted in clinical benefit (for example, improved or stabilized HbA1c control or fewer episodes of symptomatic hypoglycemia or hyperglycemia).

Replacement pumps:

The replacement of external insulin pumps is considered medically necessary when the following criteria have been met:

1. The device is out of warranty; and
2. The device is malfunctioning; and
3. The device cannot be refurbished.

Note: The medical necessity of the replacement of an external insulin pump for pediatric individuals (under 18 years of age) who require a larger insulin reservoir will be considered on a case-by-case basis. The following information is required when submitting requests:

1. Current insulin pump reservoir volume; and
2. Current insulin needs; and
3. Current insulin change out frequency required to meet individual needs.

Not Medically Necessary:

The use of an external insulin pump is considered not medically necessary when the criteria above have not been met.

Continued use of an external insulin pump is considered not medically necessary when continued use criteria above have not been met.

Replacement of currently functional and warranted external insulin pumps is considered not medically necessary when the criteria above have not been met, including when the request is to upgrade to a newer pump with additional features.

Diabetes is one of the most common chronic diseases in the United States (U.S.), with approximately 37 million Americans with diagnosed disease and the fourth leading cause of death in the U.S. (American Diabetes Association, 2023).

Individuals with diabetes mellitus have impaired metabolism of carbohydrate, protein and fat as a result of abnormal production or utilization of insulin, the hormone secreted by the pancreas that controls blood sugar. When poorly controlled, diabetes leads to cardiovascular disease, retinal damage that could lead to blindness, peripheral nerve damage, and kidney damage.

There are several types of diabetes. Type 1 can occur at any age but is most commonly diagnosed from infancy to late 30s. In type 1 the pancreas produces little to no insulin, and the body’s immune system destroys the insulin-producing cells in the pancreas. Type 2 diabetes typically develops after age 40, but has recently begun to appear with more frequency in children. Individuals with type 2 diabetes still produce insulin, but the body does not produce enough or is not able to use it effectively.

Type 1 diabetes is treated with insulin. Insulin administration may be done in several ways. The most common method is multiple daily injections (MDI) via a syringe and subcutaneous injection. For some individuals with diabetes, the use of multiple daily insulin injection therapy is insufficient to provide adequate control of blood sugar levels. In such cases, an external insulin pump may be recommended. These devices are worn externally and are attached to a temporary subcutaneous insulin catheter placed into the skin of the abdomen. The pump can be set to administer the insulin at a set (basal) rate or provide injections (bolus) as needed. The pump typically has a syringe reservoir that has a 2- to 3-day insulin capacity. The purpose of the insulin pump is to provide an accurate, continuous, controlled delivery of insulin which can be regulated by the user to achieve glucose control.

Since the publication of the Diabetes Control and Complication Trial (1993), there has been a growing body of evidence to suggest that improved blood glucose control in diabetics leads to improved clinical outcomes, especially with regard to long-term diabetic complications. This has led to an approach of intensive diabetic management to maintain blood glucose to as near normal as possible over all hours of the day and over the life span of the individual. Implementation of this approach requires the individual to be capable of, and committed to, a day-to-day medical program of some complexity. It requires ongoing compliance with multiple daily glucose measurements and insulin injections accompanied by appropriate adjustments in insulin dose. Additionally, successful intensive diabetic management requires response to a variety of external factors including changes in diet, exercise and the presence of infection. Despite this complexity, many motivated individuals can, with adequate training and support, achieve significant improvements in glucose control using this approach. Both multiple daily insulin injections and continuous subcutaneous insulin infusion via an external pump are effective means of providing intensive diabetic management (DCCT Research Group, 1993). Controlled trials comparing these insulin delivery methods show that in most individuals overall blood glucose control is the same or slightly improved with insulin pump treatment. However, in diabetics treated with insulin pumps, hypoglycemia is less frequent and nocturnal glucose control is improved.

The evidence supports the efficacy of the external insulin infusion pump for properly trained diabetics who are not well controlled on intensive, multi-dose insulin therapy. Benefits are seen in long-term control as shown by lowered glycosylated HbA1c levels. In addition, stability of blood glucose self-measurement values as well as surveyed functional status and quality of life outcomes have been shown to improve in individuals using continuous insulin pump therapy (Hirsch, 1990; Kitzmiller, 1991; Pickup, 2002; Selam, 1990; Grunberger, 2014).

The benefit of insulin pump use for individuals with type 2 diabetes was established by the results of the OpT2mise Study (Aronson, 2016; Conget, 2016; Reznik, 2014). This well designed and conducted randomized controlled trial (RCT) concluded that for individuals with poorly controlled type 2 diabetes despite MDI, use of an insulin pump can be a valuable treatment option.

While standard insulin pumps operate on electricity, mechanical disposable insulin pumps (for example, the V-Go) have been proposed as an alternative. The existing evidence addressing this device is mainly in the form of short-term, retrospective studies (Boonin, 2017; Johns, 2014; Lajara, 2016a and 2016b; Meade, 2021; Rosenfeld, 2012; Sutton, 2016; Winter, 2015). A comparative trial reported by Lajara (2015) involved 204 subjects using the V-Go device vs. MDI. As with the above-described study, significant improvements in HbA1c concentration and decreases in required insulin volume were reported (-1.58% at 27 weeks and, p<0.001 for both).

Raval and colleagues (2019) reported the results of a retrospective cohort study involving data derived from the HealthCore Integrated Research Database. The study looked at 118 matched pairs of individuals with type 2 diabetes undergoing treatment with either the V-Go wearable insulin pump or MDI with 12 months of data available. At the end of 12 months of treatment both cohorts were reported to have improvements in percent HbA1c ≤ 9%, but no differences between groups were noted (p<0.001 for V-Go group and p=0.046 for the MDI group; p=0.263 between groups). Insulin prescription fills were reported to be lower in the V-Go group (mean change: -0.8 vs. +1.8 fills, p<0.001). A decrease in insulin total daily dose during the last 6 months of follow-up was also reported in the V-Go group (mean change in insulin units per day: -29.2 vs. +5.8, p<0.001).

Grunberger (2020) reported the results of a prospective open label case series study initially involving 188 subjects with type 2 diabetes and suboptimal glycemic control (HbA1c ≥ 7%) treated with the V-Go device. At 12 months, 112 subjects (60%) remained in the study, with 66 still on V-Go device. The authors reported a mean decrease in HbA1c from baseline of - 0.64%; (p=0.003) and total daily dose of insulin of 12 units/day (p<0.0001) at 12 months. However, due to the high dropout rate and lack of blinding, the value of this data is uncertain.

At this time, the available data comparing addressing the V-Go device appears to demonstrate equivalent outcomes to standard battery-operated insulin pump devices.

Back-up Insulin Infusion Pumps

Modern external infusion pumps appear safe and reliable, and studies reviewed did not indicate a need for a “back-up” pump. If an insulin pump fails, an individual can and should revert to daily multiple injections until the pump is repaired or replaced.

Insulin Infusion Pump Reservoir Issues

Some pediatric individuals experience increased insulin requirements which exceed the capabilities of the insulin reservoir of their current external insulin pump. In such cases, it may be reasonable to replace their existing pump with a model that has a reservoir that meets their insulin requirements. Requests for this type of equipment upgrade would be reviewed individually taking into account the unique needs of the individual and capacity of existing equipment.

Major Specialty Medical Society Recommendations

The ADA Standards of Medical Care in Diabetes-2023 has recommendations regarding the use of continuous glucose monitoring. These recommendations state:

6.5a An A1C goal for many nonpregnant adults of <7% (<53 mmol/mol) without significant hypoglycemia is appropriate. A
6.5b If using an ambulatory glucose profile/glucose management indicator to assess glycemia, a parallel goal for many nonpregnant adults is TIR >70% with time below range <4% and time <54 mg/dL (<3 mmol/L) <1%. For those with frailty or at high risk of hypoglycemia, a goal of >50% TIR with <1% time below range is recommended (Fig. 6.1  and Table 6.2 ). B
6.6 On the basis of health care professional judgment and the preference of the person with diabetes, achievement of lower A1C levels than the goal of 7% (53 mmol/mol) may be acceptable and even beneficial if it can be achieved safely without significant hypoglycemia or other adverse effects of treatment. B
6.7 Less stringent glycemic goals may be appropriate for individuals with limited life expectancy or where the harms of treatment are greater than the benefits. B
7.1 Diabetes devices should be offered to people with diabetes. A
7.4 The type(s) and selection of devices should be individualized based on a person’s specific needs, preferences, and skill level. In the setting of an individual whose diabetes is partially or wholly managed by someone else (e.g., a young child or a person with cognitive impairment or dexterity, psychosocial, and/or physical limitations), the caregiver’s skills and preferences are integral to the decision-making process. E
7.5 When prescribing a device, ensure that people with diabetes and caregivers receive initial and ongoing education and training, either in person or remotely, and ongoing evaluation of technique, results, and the ability to utilize data, including uploading/sharing data (if applicable), to monitor and adjust therapy. C
7.6 People with diabetes who have been using CGM, continuous subcutaneous insulin infusion (CSII), and/or automated insulin delivery (AID) for diabetes management should have continued access across third-party payers, regardless of age or A1C levels. E
7.8 Initiation of CSII and/or AID early, even at diagnosis, in the treatment of diabetes can be beneficial depending on a person’s or caregiver’s needs and preferences. C
7.18 In people with diabetes on MDI or CSII, rtCGM devices should be used as close to daily as possible for maximal benefit. A isCGM devices should be scanned frequently, at a minimum once every 8 h to avoid gaps in data. A People with diabetes should have uninterrupted access to their supplies to minimize gaps in CGM. A
7.28 Insulin pump therapy alone with or without a sensor-augmented pump low-glucose suspend feature should be offered for diabetes management to youth and adults on MDI with type 1 diabetes A or other types of insulin-deficient diabetes E who are capable of using the device safely (either by themselves or with a caregiver) and are not able to use or do not choose an AID system. The choice of device should be made based on the individual’s circumstances, preferences, and needs. A
7.29 Insulin pump therapy can be offered for diabetes management to youth and adults on MDI with type 2 diabetes who are capable of using the device safely (either by themselves or with a caregiver). The choice of device should be made based on the individual’s circumstances, preferences, and needs. A
7.30 I Individuals with diabetes who have been using CSII should have continued access across third-party payers. E
7.31 Individuals with diabetes may be using systems not approved by the FDA, such as do-it-yourself closed-loop systems and others; health care professionals cannot prescribe these systems but should assist in diabetes management to ensure the safety of people with diabetes. E
14.20 Insulin pump therapy alone should be offered for diabetes management to youth on multiple daily injections with type 1 diabetes who are capable of using the device safely (either by themselves or with caregivers) if unable to use AID systems. The choice of device should be made based on the individual’s and family’s circumstances, desires, and needs. A
14.22 A1C goals must be individualized and reassessed over time. An A1C of <7% (<53 mmol/mol) is appropriate for many children and adolescents. B
14.23 Less stringent A1C goals (such as <7.5% [<58 mmol/mol]) may be appropriate for youth who cannot articulate symptoms of hypoglycemia; have hypoglycemia unawareness; lack access to analog insulins, advanced insulin delivery technology, and/or CGM; cannot check blood glucose regularly; or have nonglycemic factors that increase A1C (e.g., high glycators). B
14.24 Even less stringent A1C goals (such as <8% [<64 mmol/mol]) may be appropriate for individuals with a history of severe hypoglycemia, limited life expectancy, or where the harms of treatment are greater than the benefits. B
14.25 Health care professionals may reasonably suggest more stringent A1C goals (such as <6.5% [<48 mmol/mol]) for selected individuals if they can be achieved without significant hypoglycemia, negative impacts on well-being, or undue burden of care or in those who have nonglycemic factors that decrease A1C (e.g., lower erythrocyte life span). Lower goals may also be appropriate during the honeymoon phase. B
14.60 A reasonable A1C goal for most children and adolescents with type 2 diabetes is <7% (<53 mmol/mol). More stringent A1C goals (such as <6.5% [<48 mmol/mol]) may be appropriate for selected individuals if they can be achieved without significant hypoglycemia or other adverse effects of treatment. Appropriate individuals might include those with a short duration of diabetes and lesser degrees of β-cell dysfunction and individuals treated with lifestyle or metformin only who achieve significant weight improvement. E
14.61 Less stringent A1C goals (such as 7.5% [58 mmol/mol]) may be appropriate if there is an increased risk of hypoglycemia. E
14.62 A1C goals for individuals on insulin should be individualized, taking into account the relatively low rates of hypoglycemia in youth-onset type 2 diabetes. E
15.8 Due to increased red blood cell turnover, A1C is slightly lower during pregnancy in people with and without diabetes. Ideally, the A1C goal in pregnancy is <6% (<42 mmol/mol) if this can be achieved without significant hypoglycemia, but the goal may be relaxed to <7% (<53 mmol/mol) if necessary to prevent hypoglycemia. B

The AACE and American College of Endocrinology (ACE) published a position statement on the integration of insulin pumps and continuous glucose monitoring in patients with diabetes mellitus (Grunberger, 2018). This document states the following:

R2.7.1 The use of an insulin pump without CGM could be used to manage persons with diabetes who are achieving glycemic targets with minimal TBR, who report infrequent episodes of symptomatic hypoglycemia, and who are using SMBG on a regular basis (at least 4 times per day for persons with T1D). Grade B; Intermediate-High Strength of Evidence; BEL
R3.5.1 Clinicians should strongly consider the discontinuation of insulin pump therapy based on an individual’s ability to use it effectively and safely or based on the personal preference of a person with diabetes to discontinue this insulin delivery modality. Grade A; Intermediate Strength of Evidence; BEL 1

Additionally, in 2023 the Endocrine Society published Management of individuals with diabetes at high risk for hypoglycemia (McCall, 2023). In this document they make the following recommendations:

Recommendation 2: We suggest using real-time continuous glucose monitoring (CGM) and algorithm-driven insulin pumps (ADIPs) rather than multiple daily injections (MDIs) with self-monitoring of blood glucose (SMBG) three or more times daily for adults and children with type 1 diabetes (T1D).
