Policy Change Allows Approval For Medicare Patients Living With Diabetes To Use Both Afrezza® And Continuous Glucose Monitoring Devices Beginning July 18

WESTLAKE VILLAGE, Calif., June 28, 2021 /PRNewswire/ -- MannKind Corporation (Nasdaq: MNKD) appreciates the recent efforts of the Centers for Medicare and Medicaid Services (CMS) in conjunction with the Medicare Administration Contractors (MACs) to implement a policy change to the Local Coverage Determination (LCD) L33822, allowing the approval to Medicare patients living with diabetes to select both Afrezza^® and Continuous Glucose Monitors (CGMs). Effective July 18, the criteria change lifts the restriction on patients of having to choose between the two diabetes tools.

"Prior to this change, Medicare denials were occurring for patients using CGMs and inhaled insulin as an alternative to injected mealtime insulin," explained Michael Castagna, PharmD, Chief Executive Officer of MannKind Corporation. "MannKind is committed to providing convenience for patients, and believes that patients should have the choice to use any of today's tools to help manage their diabetes."

MannKind requested that the Durable Medical Equipment (DME) MACs reconsider the existing language in the LCD: Glucose Monitors (L33822) to include use of inhaled insulin.  Previously, the criteria defined patients as taking insulin either with multiple daily injections or an insulin pump.  The amended definition now includes a patient that takes insulin with inhalation as an alternative.

"This is a win-win for Medicare patients and providers that serve those patients," said Stella Ilyayeva, MD, FACE, an Endocrinology, Diabetes and Metabolism specialist.  "In 2020, almost 2/3 of T1D Afrezza patients were utilizing a CGM concomitantly. I anticipate this change will open up more doors for the population of Afrezza users."

About Afrezza^®
Available by prescription, Afrezza^® (insulin human) Inhalation Powder is an ultra rapid-acting inhaled insulin indicated to improve glycemic control in adult patients with diabetes mellitus. Afrezza consists of a dry powder formulation of human insulin delivered from a small and portable inhaler. Administered at the beginning of a meal, Afrezza dissolves rapidly upon inhalation to the lung and passes quickly into the bloodstream (in less than one minute). This rapid absorption allows Afrezza to begin reducing blood sugar levels within minutes of administration. Afrezza is available in 4-unit, 8-unit and 12-unit single-dose cartridges of insulin powder that can be used, as prescribed by a health care professional, in combination with other diabetes medications to achieve target blood sugar levels. For Afrezza doses exceeding 12 units, patients may use a combination of existing cartridge strengths. For more information about Afrezza, please visit afrezza.com.
