What is an example of pharmacogenetics?

Example: Depression and Amitriptyline. The breakdown of the antidepressant drug amitriptyline is influenced by two genes called CYP2D6 and CYP2C19. If your doctor prescribes amitriptyline, he or she might recommend genetic testing for the CYP2D6 and CYP2C19 genes to help decide what dose of the drug you need.

Contractors may specify Revenue Codes to help providers identify those Revenue Codes typically used to report this service. In most instances Revenue Codes are purely advisory. Unless specified in the article, services reported under other Revenue Codes are equally subject to this coverage determination. Complete absence of all Revenue Codes indicates that coverage is not influenced by Revenue Code and the article should be assumed to apply equally to all Revenue Codes.

What is the difference between pharmacogenetics and pharmacogenomics?

In general, pharmacogenomics refers to the overall study of the many various genes that contribute to drug response . Pharmacogenetics is the study and evaluation of the inherited differences (genetic variations) that affect drug metabolism and an individual's response to medications. For the purposes of this article, the term pharmacogenetics will be used.

Why is pharmacogenetics important?

For certain medications, pharmacogenetics is already helping healthcare providers predetermine proper therapies and dosages to have a better chance of achieving the desired therapeutic effect while reducing the likelihood of adverse effects.

What is the study of genetic variability that causes individual responses to medications?

Pharmacogenetics is the study of genetic variability that causes individual responses to medications. By analyzing the genes that produce the specific drug targets or enzymes that metabolize a medication or are associated with immune response, a healthcare practitioner may decide to raise or lower the dose or even change to a different drug.

How many copies of genes are there?

Each person has two copies of most genes: one copy is inherited from the person's mother and one copy is inherited from the person's father.

Why is genetic testing important?

Testing people prior to initiating drug therapy to determine their likely response to different classes of drugs is a key emerging area of testing. Such genetic information could prove useful to both the healthcare practitioner and patient when choosing current and future drug therapies and drug doses.

When should you test for a drug?

Testing may be ordered prior to starting specific drug therapies or if a person who has started taking a drug is experiencing side effects or having trouble establishing and/or maintaining a stable dose. Sometimes a person may not experience such issues until other medications that affect the metabolism or action of the drug in question are added or discontinued.

When can a healthcare practitioner test a patient's genes?

A healthcare practitioner may test a patient's genes for certain variations that are known to be involved in variable response to a medication at any time during treatment (for example, prior to treatment, during initial phase of treatment, or later in the treatment).

Coding Early Pharmacogenomic Testing Presented Difficulties

Pharmacogenomic testing in the clinical setting has only been available since the early to mid-2000s, with the first test approved by the US Food and Drug Administration (FDA) occurring in 2005. 7 Early adopters had difficulty documenting such procedures using CPT codes for two key reasons:

Some Unique CPT Codes Now Available

The AMA acted on requests to assign many of these pharmacogenomic tests unique CPT codes for documentation purposes in 2012. 12 These CPT codes are for pharmacogenomic tests that detect specific gene variants known to impact drug therapy. The new codes went into effect in 2013.

More Work Needed to Address Challenges

Pharmacogenetic testing continues to pose challenges for health information professionals. Documenting the use of pharmacogenetic tests accurately can still be difficult since new tests may not have unique CPT codes available yet.

What is pharmacogenomics knowledge?

The Pharmacogenomics Knowledge for Personalized Medicine database (PharmGKB) is a NIH-funded resource that provides information about how human genetic variation affects response to medications, and provides a centralized resource of international gene-drug professional society prescribing guidelines, FDA label information on gene-drug recommendations, and evidence based clinical curations (Whirl-Carillo et al., 2012).

What is the study of variation in genes that encode drug-metabolizing enzymes, drug transporters, and drug targets?

Pharmacogenetics encompasses variation in genes that encode drug-metabolizing enzymes, drug transporters, and drug targets, as well as other specific genes related to the action of drugs. A slight variation in the deoxyribonucleic acid (DNA) sequence can result in a subtle change in a protein which translates into major differences in how the protein functions. The study of variations in DNA sequence as related to drug response is referred to as pharmacogenetics, and pharmacogenetic testing involves genotyping to detect relevant variants. Genetic variations can be associated with suboptimal drug response, for example poor efficacy or adverse events.

What is pharmacogenomics panel?

Pharmacogenomics Panel - Individuals with particular genotypes may find their metabolism capabilities for certain prescription drugs range from extremely poor to extremely fast, and may need to avoid or adjust to a higher or lower drug dosage in order to achieve a therapeutic effect . This test analyzes high-evidence markers for genes/loci of known pharmacogenomics value allowing clinicians to gain valuable insight into an individual's ability to metabolize drugs based on their genetic make-up. The pharmacogenomics panel reports genetic information only, currently we are not reporting medication information.

Causes

• Most drugs are broken down (metabolized) in the body by various enzymes. In some cases, an active drug is made inactive (or less active) through metabolism. In other cases, an inactive (or less active) drug is made more active through metabolism. The challenge in drug therapy is to make sure that the active form of a drug stays around long enough t...
