Coding for the Administration of COVID-19 Monoclonal Antibody Products
CMS identified specific code (s) for each COVID-19 monoclonal antibody product and specific administration code (s) for Medicare payment:
Medicare Payment for Administering COVID-19 Monoclonal Antibody Products
To ensure immediate access during the COVID-19 PHE, Medicare covers and pays for these infusions and injections in accordance with Section 3713 of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) .
Billing for Administering COVID-19 Monoclonal Antibody Products
Health care providers can bill on a single claim for administering COVID-19 monoclonal antibody products, or submit claims on a roster bill.
What is monoclonal antibody?
Monoclonal antibodies are a class of medicines that have transformed the way we prevent and treat diseases, from cancer and diseases of the immune system, to childhood viral infections. They are not chemical compounds, as most drugs are.
How can companies make monoclonal antibodies cheaper?
Another way companies can make monoclonal antibodies cheaper is by introducing second brands which can only be sold in low- and middle-income countries. One example is Herclon, another brand that Herceptin is sold as. High-income countries are the main market for monoclonal antibodies. 9.
How much does monoclonal antibody cost?
The median price for monoclonal antibody treatments in the US ranges from $15,000 to $200,000 a year.
How long does it take for monoclonal antibodies to be produced?
Most monoclonal antibodies are produced in Chinese hamster ovary cells which are typically grown in large bioreactors for around 10 to 15 days. The resulting antibodies are then purified and packaged so they can be easily administered. This whole process takes a long time and uses costly materials.

What is it called when antibodies turn down the immune system?
Antibodies can be designed to attach to different molecules in the body, for example, to turn down the immune response when it overreacts; this phenomenon, which also happens with some Covid-19 patients, is called a ‘cytokine storm’ .
How do antibodies work?
They work by binding to their specific targets – for example viruses, bacteria or cancerous cells – and making them harmless.
What is the purpose of monoclonal antibodies?
These are known as monoclonal antibodies (mAbs or Moabs). Monoclonal antibodies are used to treat many diseases, including some types of cancer. To make a monoclonal antibody, researchers first have to identify the right antigen to attack.
Why are m onoclonal antibodies used to treat cancer?
NOTE: Some m onoclonal antibodies used to treat cancer are referred to as targeted therapy because they have a specific target on a cancer cell that they aim to find, attach to, and attack.
What is the antibody that blocks HER2?
For example, trastuzumab (Herceptin) is an antibody against the HER2 protein. Breast and stomach cancer cells sometimes have large amounts of this protein on their surface. When HER2 is activated, it helps these cells grow. Trastuzumab binds to these proteins and stops them from becoming active.
Why do mAbs deliver radiation?
The drug and radiation are delivered directly to the target cells because the mAb looks for the target, then the radiation affects the target and nearby cells to a certain extent. Chemolabeled antibodies: These mAbs have powerful chemotherapy (or other) drugs attached to them. Examples include:
How are conjugated mAbs used?
These mAbs are used as a homing device to take one of these substances directly to the cancer cells. The mAb circulates throughout the body until it can find and hook onto the target antigen. It then delivers the toxic substance where it is needed most. This lessens the damage to normal cells in other parts of the body. Conjugated mAbs are also sometimes referred to as tagged, labeled, or loaded antibodies.
How do naked mAbs work?
(See Immune Checkpoint Inhibitors and Their Side Effects .) Other naked mAbs work mainly by attaching to and blocking antigens on cancer cells (or other nearby cells) that help cancer cells grow or spread.
What is a naked mAb?
They work by themselves. These are the most common type of mAbs used to treat cancer. Most naked mAbs attach to antigens on cancer cells, but some work by binding to antigens on other, non-cancerous cells, or even free-floating proteins. Naked mAbs can work in different ways.

Monoclonal antibodies are made in a lab. Scientists use the genetic code from cells that make antibodies in humans to make many copies of specific antibodies for bacteria or viruses. These antibodies are all clones from the same cell, which is how we get the term “monoclonal antibody.”
How does monoclonal antibody treatment work?
Bacteria and viruses have proteins on their outer surface called antigens. Monoclonal antibodies attach to antigens and neutralize the bacteria or virus so it can’t infect our cells.
