The Basics

Diplomat Pharmacy Inc. is the nation’s largest independent provider of specialty pharmacy services.

Diplomat Specialty Pharmacy (DSP) represents Diplomat’s traditional strength: specialty pharmacy solutions that go beyond basic care. DSP works tirelessly to help patients manage complex, chronic conditions in disease states such as oncology, immunology, and rare disease.

Diplomat Specialty Infusion Group (DSIG) complements Diplomat Specialty Pharmacy, providing specialized infusion therapies to patients nationwide.
DSIG’s customized programs keep all members of the care team informed and patients on track. Areas of excellence include bleeding disorders, alpha-1 antitrypsin deficiency, hereditary angioedema, immune globulin, and parenteral and enteral nutrition.

EnvoyHealth provides tailored solutions for healthcare innovators. Partners can strengthen their market presence through a unique blend of customization, scale, and agility. EnvoyHealth offers patient access and engagement; noncommercial pharmacy; technology services; remote patient monitoring; virtual office; and health economics and outcomes research.

Diplomat is not a PBM. However, we do offer specialty benefit management solutions as part of our payer services pillar. These include formulary and rebate management, delegated prior authorization, and more solutions aimed at improving outcomes and value.

Specialty drugs are typically administered on a recurring basis. These medications treat complex, chronic diseases and require specialized handling and administration. Diplomat has expertise across a broad range of high-growth specialty therapies, including in oncology, immunology, rare disease, and specialty infusion.

Diplomat was incorporated in Michigan on March 26, 1975.

Diplomat employed more than 2,000 people as of Dec. 31, 2017.

Diplomat’s corporate headquarters is at 4100 S. Saginaw St., Flint, MI 48507. This facility is also home to Diplomat Specialty Pharmacy (DSP)’s Great Lakes Distribution Center, our primary pharmacy distribution facility. We are licensed to dispense prescriptions and provide pharmacy services in all U.S. states and territories. To view all our locations, click here.

The store that would become Diplomat opened as Ideal Pharmacy in Flint, Michigan, in 1973. It was the fourth store in a small chain owned in part by Dale Hagerman, RPh. When Dale’s son, Phil, graduated from college in 1975, Dale traded in his stock to buy the store. The father-son team founded the company on a simple tenet: “Take good care of patients and the rest falls into place.” Today, that tradition continues—always focused on exceptional patient care.

Your Medicare Rights

You have the right to request a coverage determination from your Medicare drug plan if you disagree with information provided by the pharmacy. You also have the right to request a special type of coverage determination called an “exception” if you believe any of these apply:

  • You need a drug that is not on their drug plan’s list of covered drugs, or formulary.
  • A coverage rule (such as prior authorization requirement or a quantity limit) should not apply to you for medical reasons.
  • You need to take a non-preferred drug and want the plan to cover said drug at a preferred-drug price.

What You Need to Do

You or your prescriber can contact your Medicare drug plan to ask for a coverage determination by calling the plan’s toll-free phone number on the back of your plan membership card or by going to your plan’s website. You or your prescriber can request an expedited (24-hour) decision if your health could be seriously harmed by waiting up to 72 hours for a decision. Be ready to tell your Medicare drug plan:

  • The name of the prescription drug that was not filled. Include the dose and strength, if known.
  • The name of the pharmacy that attempted to fill your prescription.
  • The date you attempted to fill your prescription.
  • If you ask for an exception, your prescriber will need to provide your drug plan with a statement explaining why you need the off-formulary or non-preferred drug or why a coverage rule should not apply to you.

Your Medicare drug plan will provide you with a written decision. If coverage is not approved, the plan’s notice will explain why coverage was denied and how to request an appeal if you disagree with the plan’s decision.

Refer to your plan materials or call 1.800.MEDICARE for more information.
