This testing is covered under Medicare when used for any of the indications listed in A, B, and C and if it is reasonable and necessary for the patient. It is covered for ankylosing spondylitis in cases where other methods of diagnosis would not be appropriate or have yielded inconclusive results.
What is a positive HLA B27 test?
This test is a class I antigen level test. The generic sequence coding for HLA-B27 is probed and reported as either P (positive) if it is present or N (negative) if it is absent. HLA-B27 is strongly associated with ankylosing spondylitis (Marie-Strumpell disease).
When would I get an HLA-B27 test?
An HLA-B27 test may be ordered when a person has acute or chronic pain and inflammation in the spine, neck, chest, eyes, and/or joints, and the healthcare practitioner suspects the cause is an autoimmune disorder that is associated with the presence of HLA-B27. An HLA-B27 test may also be ordered when someone has recurrent uveitis.
Can ankylosing spondylitis be tested for HLA B27?
It is also to be noted that around 10-20% of patients with proven ankylosing spondylitis will test negative for HLA B27. So the negative results of a test do not indicate that someone is free from the disease.
What is the relationship between HLA-B27 and autoimmune diseases?
People with HLA-B27 have an increased likelihood of developing autoimmune diseases such as ankylosing spondylitis (AS), juvenile rheumatoid arthritis (JRA), reactive arthritis (of which one subset is Reiter syndrome), and isolated acute anterior uveitis.
What DX code covers HLA b27?

Is 80053 covered by Medicare?
For this particular claim, Medicare paid all labs except 80053 (CMP). Denial reason: "Patient responsibility - These are non-covered services because this is routine exam or screening procedure done in conjunction with a routine exam."
What pathology tests are not covered by Medicare?
Medicare does not cover the costs of some tests done for cosmetic surgery, insurance testing, and several genetic tests. There are also limits on the number of times you can receive a Medicare rebate for some tests. Your private health insurance may pay for diagnostic tests done while you are a patient in hospital.

What is the HLA B27 test?
What is the HLA-B27 test? The HLA-B27 is a blood test that is used to determine the level of a particular protein called human leukocyte antigen B27 (HLA-B27), which is also a genetic marker. The protein is an antigen that is found on the surface of white blood cells that are fighting infection in the body.
How many people test positive for HLA B27?
In general, a significant section of the population ranging around 6 to 8% will test positive for this protein. In some cases, the HLA-B27 protein can cause the immune system to attack the otherwise healthy cells of the body resulting in auto-immune diseases. In terms of statistics, only 10 to 15% of the individuals carrying this protein will end up ...
What are the symptoms of HLA B27?
The following symptoms are generally associated with an auto-immune disorder related to HLA-B27. – Inflammation of urethra accompanied by skin lesions. – Swelling or stiffness of the vertebrae in the spine, neck or in the chest area. – Recurring inflammation and swelling of the middle of the eye.
What is the effect of HLA-B27 on the immune system?
In some cases, it is believed that the similarity between the HLA-B27 antigen and the antigens found on the cellular surface of the invading microorganisms trigger the immune system to act against both the healthy and disease-causing cells.
Is HLA B27 genetically determined?
– The presence of HLA-B27 in individuals is genetically determined and in case you have a family history of diseases related to it, you have a greater risk of developing such a disease.
Do negative results mean someone is free from HLA?
So the negative results of a test do not indicate that someone is free from the disease. Each person has a distinct combination of HLA antigens depending on his or her genetic structure. The conditions associated with the antigen are usually chronic in nature and found more widely in men than in women.
Is a symtom test a diagnostic test?
The test is not an actual diagnostic test but is generally be combined with multiple other tests to confirm the suspicions about a particular disorder. So further tests can be ordered to evaluate the symptoms in more detail.
What is the diagnosis of HLA B27?
If the person has symptoms such as chronic pain, inflammation, and/ or degenerative changes to bones (as seen on X-ray), then it supports a diagnosis of ankylosing spondylitis, reactive arthritis, or another autoimmune disorder that is associated with the presence of HLA-B27.
When to order HLA B27?
An HLA-B27 test may be ordered when a person has acute or chronic pain and inflammation in the spine, neck, chest, eyes, and/or joints, and the healthcare practitioner suspects the cause is an autoimmune disorder that is associated with the presence of HLA-B27. An HLA-B27 test may also be ordered when someone has recurrent uveitis.
What is the HLA B27 gene?
Everyone has an inherited combination of HLA genes that code for the many antigens present on the surfaces of their cells. The presence or absence of each antigen creates a distinctive HLA combination for each person. HLA-B27 is found in about 6% of the U.S. population.
What happens if you have two HLA B27 positive people?
If two members of the same family are HLA-B27 positive and one of them develops a disease associated with HLA-B27, then the other person is at an increased risk of developing a similar disease.
Can a positive HLA B27 test predict autoimmune disease?
Occasionally, a family member of a person who is positive for HLA-B27 and has an autoimmune disorder may be tested, but the test result cannot be used to predict whether the tested person will develop a related autoimmune disease. (© 1995-2017).
Can HLA B27 be a male or female?
Though the diseases associated with HLA-B27 occur more frequently in men, women can also be affected. However, the signs and symptoms related to the diseases can often be milder in women. With new genetic testing methods, it is now possible to separate HLA-B27 into subtypes.
Can someone with HLA B27 develop a disease?
Likewise, someone who has the HLA-B27 antigen will not necessarily develop one of these conditions. Researchers are trying to determine what factors contribute to the higher likelihood of people with HLA-B27 developing these particular diseases and what actually triggers them.
What happens if you test positive for HLA-B27?
Remember, only 2% of people with a positive HLA-B27 go on to develop ankylosing spondylitis, which is the main autoimmune disease associated with this test. However, people who have a positive HLA-B27 AND have a first-degree relative with ankylosing spondylitis have a 15% to 20% risk of developing the disease at some point during their lifetime.
Why HLA B27?
Why having a HLA-B27 increases risk of having ankylosing spondylitis as well as a host of different autoimmune diseases is still uncertain: arthrogenic peptide hypothesis, molecular mimicry, free heavy chain hypothesis, and unfolded protein hypothesis.
What percentage of people with psoriatic arthritis have a positive HLA-B27?
About 50% of people with psoriatic arthritis that involves the spine have a positive HLA-B27. 60% of people diagnosed with reactive arthritis have a positive HLA-B27. These people tend to have more severe symptoms, non-joint symptoms (e.g., uveitis), and it tends to last longer.
What percentage of African Americans have positive HLA B27?
Here are a few stats to put things into perspective. About 6 to 9 % of Caucasians and 3 % of African-Americans have a positive HLA-B27. However, having a positive HLA-B27 increases a person’s risk of ankylosing spondylitis by 50 to 100 times.
Is HLA B27 a good antigen?
HLA-B27 antigen. HLA-B27 is a genetic test. The majority of people who have a positive HLA -B27 are perfectly healthy. HOWEVER, having a positive HLA-B7 can put you at increased risk of developing what we call spondyloarthritis-associated diseases. This is a family of autoimmune diseases.
Can you get spondyloarthritis with HLA B27?
Technically not unless a family member is experiencing symptoms suggestive of ankylosing spondylitis, psoriatic arthritis, inflammatory bowel disease, or any other spondyloarthritis-associated disease. Remember, only 2% of people with a positive HLA-B27 go on to develop ankylosing spondylitis, which is the main autoimmune disease associated ...
Clinical Significance
HLA-B27 Antigen - HLA-B27 is found in 90% of patients with ankylosing spondylitis and 80% in Reiter's disease. Ankylosing spondylitis affects 1 in 1000 caucasians. Ankylosing spondylitis is 10 times more common among individuals with HLA-B27 compared to individuals without this antigen.
