In its initial 40 years, Medicare did not offer outpatient drug prescription coverage, which was problematic for some people. However, soon Medicare came up with their part D, which offered coverage for various drugs compared to parts A and B. Medicare prescription coverage for Part A and B only covers for inpatient drugs or the medication prescribed by a clinical doctor. 

Medicare part A and B cover the drugs that the doctors inject or infuse into the patient admitted to the hospital. On the other hand, Medicare part D covers almost all outpatient prescriptions. But it is necessary to register yourself into this program when registering for Medicare.

Furthermore, each part of Medicare has some rules and requirements to cover a specific drug or medication. This article will discuss the criteria for the prescription coverage that Medicare offers to its payees and what medication a specific part of Medicare covers.  

Medicare Part A Prescription Coverage Prerequisites

Patients’ hospital stay that lasts less than 60 days falls under part A coverage. You won’t have to pay anything if you have enrolled yourself in Medicare part A. However, if your stay exceeds 60 days, then you will have to compensate from your account. 

Medicare part A pays for all medications used while a patient was admitted to the hospital. For instance, drugs like anesthesia that are necessary during an operation fall in Medicare part A coverage. Moreover, Medicare part A covers any medicine the doctor injects into the patient during their admission. And drugs, which are a part of their treatment process in the hospital.

In Medicare part A, the specific amount of $1364 deducts in each benefit period. As the patient gets admitted to the hospital, the period begins and finishes once you leave the hospital and don’t come back before 60 days.

Medicare Part B Prescription Coverage Prerequisites

Medicare part B covers all the prescriptions your doctors recommend you in their clinic. Most of these medications or drugs are injectable or infusible. Either way, the patient will require doctors’ directions and guidance before using these prescriptions.

Nonetheless, these types of medications fall under the coverage of Medicare, and the patient having part b plan will not have to pay for it from his/her account. 

Below we will mention all the prescriptions that Medicare part B provides coverage for:


Medicare part B covers different types of vaccinations. It offers a flu shot every year during the flu season. Furthermore, pneumococcal shots also fall under part B of Medicare to keep ear infections and bloodstream infections at bay. 

A patient with the risk of Hepatitis B is also eligible for the Hepatitis shot in the Medicare part B.

Medications That Require a Durable Medical Apparatus

Certain medications require a specific apparatus to inject into the patient. These medications, which require an apparatus, also fall under part B coverage. For example, Medicare will pay for the medicine used in nebulizers and insulin pumps. 

A Cancer Drug That Can Be Oral as Well as Injected

Some oral and injectable drugs show similar results; Medicare part B pays for these types of drugs. Medicare Part B provides coverage for an infusible or injectable drug for a cancer patient.

Anti-Rejection Drugs

The human body does not accept a transplanted organ; therefore, to reduce the body’s ability to reject the transplanted organ, doctors inject patients with Immunosuppressive drugs or anti-rejection drugs. Medicare part B provides coverage for these drugs.

Antiemetic Drugs

Medicare part B covers antiemetic or anti-nausea drugs given during chemotherapy treatment. But it is necessary to give the drug as soon as possible or within 48 hours of chemotherapy.

Tube Feeding

Tube feeding supplies essential nutrients to patients’ bodies at that stage of the disease where they cannot eat food. All the essential nutrients pass through the tubes into their bodies, and Medicare part B covers this process’s cost.


Antigens are the doctors’ medications or their experienced staff to strengthen the immune system paid by Medicare part B. This is because the patient cannot take these medications without the doctor’s guidance. 

Injectable Medications

Several diseases require the doctors to inject the patients with the drug to lighten the symptoms of inflammation. Psoriasis and inflammatory bowel disease are two of the many conditions in which the doctors prescribe injectable drugs. 

Rules of Medicare Part B Prescription Coverage

The most important rule in the Medicare part B prescription coverage is that the doctor prescribes the drug or medication. If a patient prescribes a drug or medication to himself, those drugs will fall under part D of Medicare, even if prescribed in the hospital. 

The most enticing part about part B coverage is that they cover 80% of the bills after paying the part B deductible.

Rules of Medicare Part D Prescription Coverage

The prime purpose of the Medicare part D is to make outpatient medications budget-friendly for the Medicare payee. 

The following are the prerequisites for the coverage of drugs under the Medicare part D:

  1. The drug must have a prescription to avail it without any cost.
  2. The purpose of the drug must be medical related.
  3. Make sure that Medicare part A and B don’t already cover the drug. 
  4. The USA should be supplying the drug. 

Medicare part D covers antidepressants, anticonvulsants, and immunosuppressive drugs. However, there are some drugs that Part D does not cover because they do not fulfil the requirements mentioned above of part D. 

Bottom Line

To conclude, prescriptions can sometimes cost you a fortune, but they are inevitable. Above all, many people cannot afford these drugs and medications. Getting coverage for your prescriptions will lighten your burden. That’s why Medicare has different parts that make prescriptions affordable to the masses. 

The patient must meet all the requirements to get the coverage for prescriptions. Furthermore, following all rules and regulations to get your prescription is also essential when enrolling for any part of Medicare.
