What positive ANA ICD codes can I use?

There are two positive ANA ICD codes that can be utilized. We will not be providing an exhaustive list of specific autoimmune diseases associated with ANA, such as Lupus, Scleroderma, and Rheumatoid Arthritis. This concise guide focuses solely on the presence of ANA in the body.

Here are the two positive ANA-related ICD-10 codes you can use:

  1. R76.0 - Raised antibody titer

This ICD-10 code is meant to be used on a patient who has undergone an antibody titer test, and the test results show the presence of antinuclear antibodies in them. What is meant by raised is that the titer test has detected many antibodies in the blood. If the titer test was used to check for antinuclear antibodies, this ICD-10 code could be used.

  1. R76.8 - Other specified abnormal immunological findings in serum

This ICD-10 code is meant to be used on a patient who has undergone a particular test that involves examining serum, and in this serum, professionals obtained abnormal immunological findings. This can include antinuclear antibody patterns. Patterns can be homogenous, speckled, centromere, cytoplasmic, mitochondrial, nucleolar, peripheral, or a mixture of some.

Please note that these codes are not valid as principal diagnoses because they are used to explain a patient’s condition simply. In the context of these ICD-10 codes, these can be used alongside ICD-10 codes for specific autoimmune disorders/diseases that a patient has.

Are these positive ANA ICD codes billable?

Yes. Despite being invalid as principal diagnoses, these positive ANA-related ICD-10 codes are valid (in general) and billable.

Clinical information on ANA:

ANA stands for Antinuclear Antibodies. Instead of targeting harmful bacteria and viruses, these particular antibodies mistakenly attack our cells and tissues. If left unattended, these antibodies can inflict damage beyond our cells and tissues, affecting areas like our skin, joints, muscles, and more. It is crucial to address this issue promptly to prevent further complications.

ANAs are also considered to be signs of autoimmune diseases, such as Lupus, Scleroderma, and Rheumatoid Arthritis, to name a few.

A person who might have ANAs will likely exhibit/experience the following symptoms:

  • Feeling fatigued and weak
  • They frequently get fevers, or their fevers persist too long
  • They have pain in their muscles and/or joints
  • Their joints feel stiff
  • Their joints are swelling
  • Their hands and/or feet feel numb
  • Their hands and/or feet feel tingles
  • They become sensitive to light or have an increased sensitivity to it
  • They have hair loss

Synonyms include:

  • Autoantibody titer positive
  • High antibody titer
  • Raised antinuclear antibody
  • Anti-nuclear factor positive
  • Anticentromere antibody pattern
  • Homogeneous antinuclear antibody pattern
  • Peripheral antinuclear antibody pattern
  • Speckled antinuclear antibody pattern

Commonly asked questions

Are there any more ICD-10 codes for positive ANA?

For similar ones to the two listed above, no. The closest to these would be ICD-10 codes specific to autoimmune diseases/disorders related to the presence of ANA.

How do healthcare professionals check for ANA?

They conduct an ANA Test where they draw blood from the patient to test in a laboratory setting. This blood test may cause dizziness, bruising, soreness, and the feeling of fainting. Patients undergoing this test must inform the professional if they took any medicine, which may affect the results.

How is ANA addressed?

That depends. Just because a person is positive for ANA doesn’t mean they have an autoimmune disease or some other problem causing it. It might be just a result of medicine use. If the presence of ANA points to specific problems, then those problems must be addressed. Treatment will depend on the problem, especially if they are autoimmune diseases.
