These services may or may not be covered by all HealthPartners plans. Please see your plan documents for your own coverage information. If there is a difference between this general information and your plan documents, your plan documents will be used to determine your coverage.

Administrative Process

Prior authorization is required for an artificial pancreas system (transmitter and receiver (S1035-S1037)

Prior authorization is not required for the following:

  • Continuous Glucose Monitoring Systems (CGMS), transmitter, sensors and receivers
  • Artificial pancreas sensor (S1034)
  • A combined or integrated continuous subcutaneous insulin infusion and blood glucose monitoring system.

Note: Items listed in this policy are covered under Durable Medical Equipment (DME) benefits unless specified otherwise in your plan documents. Please see your plan documents or call Member Services if you need more information.


An artificial pancreas system is covered subject to the indications listed below and per your plan documents.

Continuous glucose monitoring system is generally covered subject to your plan documents.

Indications that are covered

An FDA approved artificial pancreas (i.e. MiniMed® 670G hybrid closed looped system) may be covered when the following criteria are met:

  1. The member is 14 years of age or older;
  2. The member has diagnosis of type one diabetes;
  3. The member requires a minimum of eight units per day of insulin;
  4. The prescribing provider must be an endocrinologist;
  5. The member has demonstrated the ability to perform a minimum of four blood glucose tests per day; and
  6. Documentation submitted supports one or more of the following indications are present:
    1. Hypoglycemia unawareness;
    2. Nocturnal hypoglycemia is suspected;
    3. Frequent problems with hypoglycemia and hyperglycemia refractory to multiple adjustments in self-monitoring of blood glucose and insulin administration;
    4. The member has unexplained, large fluctuations in preprandial glucose values;

Coverage of artificial pancreas transmitters & receivers are limited to one per person for expected life of the device because these are covered under warranty. Replacement of eligible equipment may be covered if the estimate for repairs is not cost effective and the item has exceeded manufacturer life expectancy.

Note: Members should contact the manufacturer or vendor for any needed repairs or replacements during the warranty period

Indications that are not covered

  1. An artificial pancreas is not covered for any other conditions, including but not limited to those listed below, because the safety and/or efficacy cannot be established by review of the published peer-reviewed literature:
    1. Pregnant women with pregestational type 1 diabetes;
    2. Gestational diabetes.
  2. Replacement of an artificial pancreas while under manufacturer warranty.
  3. Replacement or repair of any covered items, if the items are (i) damaged or destroyed by member misuse, abuse or carelessness, (ii) lost; or (iii) stolen.
  4. Supplies not listed above that are mainly for comfort or convenience (such as covers to use in the shower), are not covered per your member contract.
