Rheumatoid arthritis with rheumatoid factor, unspecified. M05.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2019 edition of ICD-10-CM M05.9 became effective on October 1, 2018.
Some signs and symptoms of rheumatoid arthritis include:
The "normal" range (or negative test result) for rheumatoid factor is less than 14 IU/ml. Any result with values 14 IU/ml or above is considered abnormally high, elevated, or positive.
The red blood cells clump if rheumatoid factor is present. A titer is an indicator of how much the agglutination test blood sample can be diluted before rheumatoid factor is undetectable. A titer of 1:20 indicates that rheumatoid factor can be detected when 1 part of blood is diluted by up to 20 parts saline.
Rheumatoid factor is present in about 80% of adults (but a much lower proportion of children) with rheumatoid arthritis. What are the normal ranges for rheumatoid factor? The "normal" range (or negative test result) for rheumatoid factor is less than 14 IU/ml.
Rheumatoid arthritis with rheumatoid factor, unspecified M05. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM M05. 9 became effective on October 1, 2021.
Under ICD10, M05 and M06 diagnosis codes are reasonable proxies to identify seropositive and seronegative RA with high sensitivity and positive predictive values if lab test results are not available.
A positive rheumatoid factor test result indicates that a high level of rheumatoid factor was detected in your blood. A higher level of rheumatoid factor in your blood is closely associated with autoimmune disease, particularly rheumatoid arthritis.
Seropositive is diagnosed when blood tests return positive results (among other tests), and seronegative is diagnosed when blood tests return negative results (among other present signs and symptoms).

79 for Rheumatoid arthritis with rheumatoid factor of multiple sites without organ or systems involvement is a medical classification as listed by WHO under the range - Arthropathies .
Tested randomly, a positive RF result could sometimes show up in a person without arthritis or other autoimmune disease symptoms, but who has a family history of them, such as RA. But that doesn't mean they'll develop autoimmune problems. “Without clinical correlation, it doesn't mean much,” says Dr. Schulz.
A low number (negative result) most often means you do not have rheumatoid arthritis or Sjögren syndrome. However, some people who do have these conditions still have a negative or low RF. Normal value ranges may vary slightly among different laboratories.

Having seropositive RA means your blood has antibodies that can attack your body and inflame your joints. They're called anti-cyclic citrullinated peptides (your doctor may call them anti-CCPs), or anti-citrullinated protein antibodies (ACPAs).
The condition affects everyone differently, and symptoms can change over time. But one possible difference is that people who are seropositive commonly get firm lumps on or near their affected joints called rheumatoid arthritis nodules. People who are seronegative generally don't get these nodules.
A positive ANA test means that your body is producing antibodies that are attacking normal cells instead of foreign organisms. A high level of this antibody could mean that your immune system is attacking itself. Since RA is an autoimmune disease, many people with RA have positive ANA tests.
