DESCRIPTION

Biological Products

Biological products are regulated by the Food and Drug Administration (FDA) and are used to diagnose, prevent, treat and cure diseases and medical conditions. Biological products are a diverse category of products and are generally large, complex molecules. These products may be produced through biotechnology in a living system, such as a microorganism, plant cell, or animal cell, and are often more difficult to characterize than small molecule drugs.

The nature of biological products, including the inherent variations that can result from the manufacturing process, can present challenges in characterizing and manufacturing these products that often do not exist in the development of small molecule drugs. Slight differences between manufactured lots of the same biological product (i.e., acceptable within-product variations) are normal and expected within the manufacturing process. As part of its review, FDA assesses the manufacturing process and the manufacturer’s strategy to control within-product variations. These control strategies are put in place to help ensure that manufacturers produce biological products with consistent clinical performance.

A biosimilar is a type of biologic that is highly similar to an already approved biologic medicine. To be called a biosimilar drug, a biological drug must be shown to be as safe as, work as well as, and work in the same way as its reference drug.

Reference Products

A reference product is the single biological product, already approved by FDA, against which a proposed biosimilar product is compared. A reference product is approved based on a full complement of safety and effectiveness data. A proposed biosimilar product is compared to and evaluated against a reference product to ensure that the product is highly similar and has no clinically meaningful differences.

Biosimilar Products

Biosimilar products are versions of reference products and may offer more affordable treatment options to patients. Biosimilar products are approved through different abbreviated pathways that avoid duplicating costly clinical trials. Biosimilar products are not generics, and there are important differences between biosimilar and generic drugs. Generic drugs contain the same active ingredient of the brand name drug. Biosimilar manufacturers must demonstrate that the biosimilar is highly similar to the reference product, except for minor differences in clinically inactive components. Biosimilar manufacturers must also demonstrate that there are no clinically meaningful differences between the biosimilar and the reference product in terms of potency, safety and effectiveness. FDA requires biosimilar products to meet the Agency’s rigorous approval standards. Patients and health care professionals are able to rely upon the safety and effectiveness of the biosimilar product, just as they would the reference product.

The covered and non-covered/non-formulary biologic agents/biosimilar products addressed in this policy are as follows:

^{*Medications listed above include both branded and unbranded versions of the product unless otherwise specified.1Avastin may be preferred product for ocular disease indications only as outlined in the State and School Employees’ Health Insurance Plan - Intravitreal Angiogenesis Inhibitors medical policy.}

POLICY EXCEPTIONS

State Health Plan (State and School Employees): Self-administered drugs may be covered under a prescription drug benefit plan administered by the State Health Plan’s Pharmacy Benefit Manager. Please perform a formulary drug search at  https://www.dfa.ms.gov/cvs-caremark and submit any required Prior Authorization Requests for coverage determination to the Plan’s Pharmacy Benefit Manager. Services related to delivery and/or administration of a self-administered drug are not covered under the medical benefit.

POLICY GUIDELINES

Medical Policy Manual coverage guidelines should not be used in lieu of the Participant's specific benefit plan language outlined in the Mississippi's State and School Employees’ Life and Health Insurance Plan.

Medically Necessary is defined as those services, treatments, procedures, equipment, drugs, devices, items or supplies furnished by a covered Provider that are required to identify or treat a Participant's illness, injury or Mental Health Disorders, and which Company determines are covered under this Benefit Plan based on the criteria as follows in A through D:

A. consistent with the symptoms or diagnosis and treatment of the Participant's condition, illness, or injury; and

B. appropriate with regard to standards of good medical practice; and

C. not solely for the convenience of the Participant, his or her Provider; and

D. the most appropriate supply or level of care which can safely be provided to the Participant. When applied to the care of an Inpatient, it further means that services for the Participant's medical symptoms or conditions require that the services cannot be safely provided to the Participant as an Outpatient.

For the definition of medical necessity, “standards of good medical practice” means standards that are based on credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, and physician specialty society recommendations, and the views of medical practitioners practicing in relevant clinical areas and any other relevant factors. BCBSMS makes no payment for services, treatments, procedures, equipment, drugs, devices, items or supplies which are not documented to be Medically Necessary. The fact that a Physician or other Provider has prescribed, ordered, recommended, or approved a service or supply does not in itself, make it Medically Necessary.
