What Positive PPD ICD-10 codes can I use?

If you're looking for Positive PPD ICD codes, please note that there are no ICD codes that mention Positive PPD in their names. That doesn't mean there aren't any.

We'd like to point out that finding the code can be a bit challenging, but the closest code to use for this is R76.11 — Nonspecific reaction to tuberculin skin test without active tuberculosis. You can use this code when the patient has a positive PPD result but no clinical or radiographic evidence of active TB disease.

If the positive PPD is part of a routine screening process rather than a diagnostic evaluation, the appropriate code would be Z11.1 – Encounter for screening for respiratory tuberculosis. This indicates that the test was conducted for preventive or public health purposes, rather than in response to symptoms.

In cases where the patient is determined to have latent tuberculosis infection (LTBI), but no current signs of disease, you may use Z86.15 – Personal history of latent tuberculosis infection. This is appropriate for documenting patients who have been treated for latent TB or have a known history of infection without progression to active disease.

Occasionally, Z22.7 – Carrier of other specified bacterial diseases might be used to indicate TB carrier status, but this is less commonly applied in clinical practice and should be supported by specific documentation.

Are these Positive PPD ICD-10 codes billable?

Yes, the ICD-10-CM codes listed below are billable for use in clinical documentation and claims submission.

Clinical information

PPD is short for purified protein derivative. It's a solution that's used to administer the Mantoux test.

The Mantoux test, or tuberculin skin testing, is a type of procedure that's designed to check patients for a specific bacterial infection. The bacteria it seeks to detect are Mycobacterium tuberculosis.

This test is done by injecting PDD into the forearm. The patient must return to the healthcare professionals within 48 to 72 hours. If there is a bump of a specific size, the patient will test positive for being infected with Mycobacterium Tuberculosis. The specific size is 5, 10, or 15+, depending on the patient's underlying conditions, comorbidities, and other risk factors.

Frequently asked questions

Does a positive PPD result mean the patient has tuberculosis?

No, a positive PPD result does not necessarily mean the patient has active tuberculosis. It indicates that the person's immune system has been exposed to Mycobacterium tuberculosis, but further evaluation is needed to determine if the infection is active or latent.

Is a positive PPD result enough to diagnose a person with tuberculosis?

No, a positive PPD alone is not enough to diagnose tuberculosis. Diagnosis of active TB requires additional tests such as a chest X-ray, sputum culture, or other imaging and laboratory studies to confirm active disease.

What does it mean if Mycobacterium tuberculosis is latent?

Latent tuberculosis means the bacteria are present in the body but inactive, causing no symptoms and not contagious. However, there is a risk that the infection can become active in the future, especially if the immune system becomes weakened.
