Lines of Business: TrueBlue clinical policies are subject to all applicable laws and government regulatory requirements of the geographical areas served. Refer to the pertinent government and plan documents for each geographical area for guidance. Individual member benefits must be verified.
Policy Definition: TrueBlue covers health care service/items when they are a plan benefit, medically
necessary and not prohibited from coverage by state or federal laws and/or regulatory requirements. This TrueBlue clinical policy addresses the medical evidence supporting the use of disposable continuous subcutaneous insulin infusion (CSII) pumps, also referred to as “insulin patch pumps”.TrueBlue considers the use of disposable CSII pumps to be investigational as the effectiveness of its use has not been established in peer reviewed professional literature. These clinical policies, along with other sources, such as plan benefits and state and federal laws and regulatory requirements, including any state or plan specific definition of medically necessary, are considered by TrueBlue when making coverage determinations.
Coverage Policy:
TrueBlue considers the use of disposable CSII pumps, also referred to as “insulin patch pumps” to be investigational; and therefore, a finding of medical necessity is not supported.
Policy contains:
OmniPod® Insulin Management System.
V‐Go™ Disposable Insulin Delivery System.

FOR MEDICARE MEMBERS ONLY:
TrueBlue considers the use of disposable CSII pumps, also referred to as “insulin patch pumps” to be clinically proven and, therefore, medically necessary only after demonstration that standard therapies have not been effective.
Limitations:
This policy only applies to the disposable CSII pumps and does not apply to standard insulin pumps.Alternative Covered Services:
Multiple daily injections of insulin.
Non-disposable external continuous infusion insulin pumps.
Background:
Intensive insulin therapy is an aggressive treatment approach for persons with diabetes that requires close monitoring of blood glucose levels and frequent doses of insulin. Innovations in insulin delivery and glucose monitoring are designed to improve glycemic control and quality of life (QOL) while limiting adverse effects, such as hypoglycemia and weight gain. These advances include continuous subcutaneous insulin infusion (CSII), real-time continuous glucose monitoring (CGM) and sensor-augmented pumps, which combine rt-CGM with CSII. Intensive insulin therapy consists of CSII using rapid-acting insulin or multiple (at least 3) daily injections (MDI) along with glucose monitoring.
An Agency for Healthcare Research and Quality systematic review of randomized controlled trials (RCTs) found that CSII and MDI have similar effects on glycemic control and hypoglycemia for children or
adolescents with type 1 diabetes mellitus (T1DM) and for adults with type 2 diabetes mellitus (T2DM); CSII has a favorable effect on HbA1c in adults with T1DM. (Golden 2012; Yeh 2012) For glycemic control, rt-CGM is superior to self-monitoring of blood glucose (SMBG) “finger stick”, and sensor-augmented insulin pumps are superior to MDI and SMBG, without increasing the risk for hypoglycemia. Adolescents and adults with T1DM reported better overall QOL with CSII than those treated with MDI. These data suggest that intensive insulin therapies designed to optimize glycemic control can be individualized to maximize treatment satisfaction and QOL.
Despite these developments, many persons with diabetes continue to experience considerable fear of hypoglycemia, which may compromise care and treatment adherence, leading to worsening metabolic control. (Anhalt 2010) Traditional CSII pumps are connected to the body via an infusion set and tubing for delivering insulin, but the tubing can kink or disconnect and compromise convenient and discreet use. As a result, a number of external insulin infusion “patch” pumps have been developed that involve no visible tubing, adhere to the body, are partially or completely disposable, and may be worn and operated discreetly under clothing. Some require a separate wireless controller device, and others include all necessary control components. (Anhalt 2010)
According to the American Diabetes Association (ADA) (2013), strong evidence indicates most people with T1DM should be treated with MDI injections (3 to 4 injections per day of basal and prandial insulin) or CSII using insulin analogs to reduce hypoglycemia risk that matches prandial insulin to carbohydrate intake,
pre-3 meal blood glucose, and anticipated activity. For persons with T2DM, due to its progressive nature insulin therapy may eventually be indicated. (ADA 2013)
The American Association of Clinical Endocrinologists (AACE) Consensus Panel on Insulin Pump
Management (2010) defined the ideal candidate for CSII pump therapy as a motivated and DM-educated person with T1DM or insulinopenic T2DM who currently performs 4 or more insulin injections and 4 or more self-monitored blood glucose measurements daily and is willing and intellectually and physically able to undergo the rigors of insulin pump therapy initiation and maintenance. (Grunberger 2010)
Eligible candidates should be capable of self-management through frequent self-monitored blood glucose measurements (at least initially) and/or the use of a continuous glucose sensor device. Candidates must be able to master carbohydrate counting and insulin correction and adjustment formulas and troubleshoot problems related to pump operation and blood glucose levels. Finally, patients should be emotionally mature, with a stable life situation, and willing to maintain frequent contact with members of their health care team, in particular their pump-supervising physician. (Grunberger 2010)
Both guidelines emphasize the choice of CSII device should be based on the patient’s abilities, goals and needs, but neither guideline specifically recommends one device, disposable or non-disposable, over another.
Regulation:
As of this writing, 2 external, disposable insulin infusion devices without visible tubing have received FDA 510(k) premarket approval as Class II devices (product code LZG) and are commercially available in
the U.S. They are:
OmniPod® Insulin Management System (Insulet Corp., Bedford, MA): indicated for patients with diabetes who require insulin. It is a single use, disposable device that consolidates the pump, tubing and subcutaneous needle into one compact unit (pod) and uses wireless remote technology called the Personal Diabetes Manager (PDM) to control the insulin pump. The unit is worn up to three days before requiring replacement.
OmniPod®® originally received FDA 510(k) clearance under the name of iXL™-II Diabetes Management System in 2003. Since then, several clearances have been granted that address modifications to the system, most notably integration of in vitro blood glucose measurement into the PDM and smaller and more lightweight models. Newer models are compatible with Novolog®/NovoRapid®, Humalog® or Apidra® brands of U-100 insulin. The next generation OmniPod® insulin pump has been cleared for marketing (K131294) and previous models will be discontinued. (Insulet® 2013)
o OmniPod®® Insulin Management System (Insulet Corp.), cleared on August 29, 2013, (K131294).
o OmniPod®® Insulin Management System (Insulet Corp.), cleared on December 7, 2012 (K122953).
o Freestyle Glucose Meter incorporated into the OmniPod®® Insulin Management Systems (Insulet Corp.) cleared on December 15, 2011 (K111669).
4 o iXL™-II Diabetes Management System with Blood Glucose Measurement (Insulet Corp.) cleared
on January 3, 2005, (K042792).
o iXL™ Diabetes Management System (Insulet Corp.) cleared on December 19, 2003, (K031373). V‐Go™ Disposable Insulin Delivery Device (Valeritas Inc., Shrewsbury, MA): indicated for adult
patients with T2DM requiring insulin.(Valeritas 2013) The V‐Go™ is a fully disposable, non‐electronic, self-contained, sterile, patient fillable, single-use disposable, subcutaneous insulin infusion device with an integrated stainless steel subcutaneous needle. After filling the V‐Go™ with insulin, the device is secured to the patient's skin over the infusion site with an adhesive-backed foam pad located on the back of the pump. It provides a continuous preset basal rate of insulin and allows for on‐demand bolus dosing around mealtimes, and must be replaced daily.
Three device models (delivering 20, 30 and 40 Units/day) are preset to address the different basal and bolus requirements of each patient with a window in the top of the pump to allow the user to check the drug in the reservoir and monitor the progress of the infusion. The manufacturer’s website further notes that if regular adjustments or modifications to the preset basal rate of insulin are required in a 24-hour period, or if the amount of insulin used at meals requires adjustments of less than 2-Unit increments, use of the V‐Go™ Disposable Insulin Delivery Device may result in hypoglycemia. (Valeritas 2013)
o V‐Go™ Insulin Delivery System (Models V‐Go™ 20, V‐Go™ 30, V‐Go™ 40; Valeritas LLC) qualified using Humalog® and Novolog®, cleared on February 23, 2011 (K103825).
o V‐Go™ Disposable Insulin Delivery Device (Models V‐Go™ 20, V‐Go™ 30, V‐Go™40; Valeritas LLC) qualified using Humalog®, cleared December 1, 2010 (K100504).
Findings:
No systematic reviews or economic analyses of either the OmniPod® or V‐Go™ external insulin infusion pumps were identified. Existing evidence from Hayes Search & Summary reports consists of small, observational studies of patients with diabetes who are experienced in the use of traditional CSII. (Hayes 2013a; Hayes 2013b) One additional study investigated single-dose and averaged-dose accuracy of
incremental basal deliveries for the OmniPod® and three durable models of insulin pumps. (Jahn 2013) The findings are summarized below:
For the V‐Go™ Disposable Insulin Delivery device, two small, low quality studies were found with insufficient reporting on patient selection criteria or health outcomes to permit conclusions on its safety or impact on health outcomes.
For the Omnipod®, results of low quality, single clinical studies suggest the OmniPod® may offer comparable short-term glycemic control to that of traditional CSII pumps in young adults and children with T1DM, and in adults with uncontrolled T2DM with severe insulin resistance. The newer, lighter OmniPod® models offer ease of use and may be preferred particularly by those with active lifestyles. These results have not been replicated in larger, higher quality studies, nor has the impact on other health outcomes been determined.
5 Results of single technical studies suggest that the OmniPod® may not improve upon the technical
limitations of traditional CSII using current insulin analogues that are not rapid enough to achieve desired peak pre-prandial insulin concentrations, catheter wear time that may affect insulin absorption, or dose accuracy. However, insulin delivery with the OmniPod® may be less susceptible to the siphon effect that might occur as a result of the position of the traditional CSII pump in relation to its tubing. The clinical significance of these findings has not been evaluated. With significant numbers of adverse effects and safety issues reported to FDA’s Manufacturer and User Facility Device Experience (MAUDE) Database, the existing research evidence of the OmniPod® is insufficient to permit conclusions
regarding its safety and effectiveness.
Study types consulted in preparing this policy: Systematic reviews, which synthesize results qualitatively or pool results from multiple studies to achieve larger sample sizes and greater precision of effect
estimation than in smaller primary studies, use pre-determined transparent methods to minimize bias, effectively applying scientific methods to a review to enhance the reliability of the findings; thus, they are rated highest in evidence grading hierarchies. Economic analyses (e.g. cost-effectiveness, -benefit or -utility studies) that report both costs and outcomes ideally based on randomized controlled trials, but excluding simple cost studies, also rank near the top of evidence hierarchies. The table below details the available systematic reviews, longitudinal studies and economic analyses for disposable insulin patch infusion pumps.

History of severe glycemic excursions.
Criterion B: The patient with diabetes has been on a pump prior to enrollment in Medicare and has documented frequency of glucose self-testing an average of at least 4 times per day during the month prior to Medicare enrollment.
7 requirements must be met:
Must be beta cell autoantibody positive OR
The patient with diabetes must be insulinopenic per the updated fasting C-peptide testing requirement defined below:
Insulinopenia is defined as a fasting C-peptide level that is less than or equal to 110% of the lower limit of normal of the laboratory's measurement method.
For patients with renal insufficiency and creatinine clearance (actual or calculated from age, gender, weight, and serum creatinine) ≤50 ml/minute, insulinopenia is defined as a fasting C-peptide level that is less than or equal to 200% of the lower limit of normal of the laboratory's measurement method.
Fasting C-peptide levels will only be considered valid with a concurrently obtained fasting glucose ≤225 mg/dL.
Levels only need to be documented once in the medical records.
Continued coverage of the insulin pump would require that the patient be seen and evaluated by the treating physician at least every 3 months.
The pump must be ordered by and follow-up care of the patient must be managed by a physician who manages multiple patients with CSII and who works closely with a team including nurses, diabetes educators, and dietitians who are knowledgeable in the use of CSII.
Glossary of terms:
Basal insulin: a low level of insulin that covers the body’s need for insulin between meals and during the night.
Bolus insulin: the additional amounts of insulin needed in response to glucose taken in during a meal. Diabetes: a metabolic disease in which the body’s inability to produce any or enough insulin causes elevated levels of glucose in the blood.
