Rheumatoid Arthritis is a crippling condition that many Medicare beneficiaries face. RA affects the joints and your immune system. Fortunately, the Medicare program covers a variety of treatments to help individuals suffering from RA.

We’ll look at how Medicare and the different supplemental Medicare options cover treatments for RA.

Medicare Covered Treatments for Rheumatoid Arthritis

Several treatments help slow the progression of damage caused by rheumatoid arthritis. Since RA is not a curable disorder, getting treatment quickly and following your rheumatologist’s directions is vital to help keep it under control.


The most common treatment for rheumatoid arthritis is prescription medications. Some come from prescription drugs you pick up from the pharmacy, while other treatments occur in the doctor’s office.

Two prescriptions are used to treat RA non-steroidal anti-inflammatory drugs, NSAIDs, and disease-modifying antirheumatic drugs or DMARDs. They can come in a biological drug form or non-biologic.

Common medications for RA include:

  • Etanercept
  • Abatacept
  • Enbrel
  • Methotrexate
  • Infliximab
  • Orencia

Joint Replacement

While the majority of treatment for RA uses DMARDS, a joint replacement might be necessary if the condition wasn’t caught quickly enough or progressed too far. A joint replacement will typically happen when a joint shows damage past the point of disability.

Physical Therapy

Since rest affects the condition negatively, causing more pain and stiffness, physical therapy can be an essential aspect of treatment. Physical therapy as a treatment for RA takes place often and on an ongoing basis.

Different parts of Medicare cover physical therapy, and the costs can vary depending on how you receive your Medicare benefits.

How much does Rheumatoid Arthritis Treatment Cost on Medicare?

Original Medicare consists of Medicare Part A and Medicare Part B. Different parts of Medicare cover the treatment of rheumatoid arthritis.

Medicare Part A

Part A covers your inpatient hospital, hospital stays, and rehab services. Medicare Part A has a large recurring deductible. Once your hospital stay reaches 60 days, you’re liable for a per-day copay each day. For skilled nursing services, you’re per-day copay begins on day 21 and goes through day 100.

Treatments covered under Medicare Part A are joint replacement surgery and physical therapy performed in an inpatient setting.

Medicare Part B

Part B covers doctor office visits, outpatient services and procedures, Medications administered in a healthcare facility, and durable medical equipment. Part B has a small annual deductible. Once that’s met, Medicare pays 80% of the Medicare-approved amount.

That leaves you with cost-sharing of 20% coinsurance and up to a 15% excess charge. RA treatments covered by Part B are office visits, outpatient physical therapy, outpatient surgery, and your biologic DMARDs. These injectable drugs are administered in the rheumatologist’s office.

Medicare Supplement Coverage for Rheumatoid Arthritis

Medicare Supplement insurance helps pay your portion of the out-of-pocket costs left over by Original Medicare and goes hand in hand with Medicare. Medigap plans will cover your copays, coinsurance, and deductibles. However, The coverage will vary depending on the plan letter you choose.

They’re also called Medigap insurance plans since a Medicare Supplement’s primary function is to cover the cost gaps in Medicare. They are standardized and regulated by the Centers for Medicare and Medicaid Services, meaning the coverage must be the same regardless of the insurance company in which you choose to enroll.

Since these plans cover the gaps in Original Medicare, they don’t offer prescription coverage for drugs filled at a pharmacy. However, they will help cover the cost of biologic DMARDs administered in the doctor’s office.

Medicare Part D Coverage for Rheumatoid Arthritis

Medicare Part D prescription drug coverage is for scripts you fill at the pharmacy. These prescription drug plans must provide coverage at least as good as the Medicare standard model. These plans are administered by private insurance companies and regulated by CMS.

Since companies cover drugs differently, reviewing your plan’s formulary is essential to ensure you choose a plan that fits your prescription needs.

Medicare Advantage Coverage for Rheumatoid Arthritis

Medicare Advantage plans are required to cover the same benefits as Original Medicare. These plans typically include prescription drug coverage and additional benefits not provided by Orginal Medicare, like dental and vision. Instead of paying the 20% and other costs associated with Original Medicare, you’ll follow the plan’s fee schedule.

Typically Medicare Advantage plans, or Medicare Part C, have fixed copays for most services and a maximum out-of-pocket to limit the amount you can spend throughout the year.
