DIAGNOSIS CODES FOR COVID-19 ANTIBODY TESTING Report code Z01. 84, “Encounter for antibody response examination,” if the antibody test is neither to confirm a current COVID-19 infection nor for follow-up of a known infection. For a current COVID-19 infection, report U07. 1 and codes for any manifestations.
To accurately assign the ICD-10 code D89. 9, disorder involving the immune mechanism unspecified, or D84. 9, immunodeficiency unspecified, the patient's immunocompromised state should not be attributed to a chronic condition or a prescribed medication therapy.
According to ICD-10-CM guidelines, clinicians may assign code Z28. 310, “Unvaccinated for COVID-19,” when the patient has not received a dose of any COVID-19 vaccine. Clinicians may assign code Z28.
Code Z23, which is used to identify encounters for inoculations and vaccinations, indicates that a patient is being seen to receive a prophylactic inoculation against a disease. If the immunization is given during a routine preventive health care examination, Code Z23 would be a secondary code.
Treating a patient who is immunocompromised poses more risks and challenges; therefore, it is important to identify a patient with this status. Code D84. 821, Immunodeficiency due to drugs, was created for immunodeficiency due to medications that interfere with the immune system.
When your immune system fails to respond adequately to infection, it's called an immunodeficiency, and you may be immunocompromised. People may also suffer from the opposite condition, an overactive immune system that attacks healthy cells as though they were foreign bodies, and that is called an autoimmune response.
ICD-10 requires only one code (Z23) per vaccination, regardless if single or combination. Report Z23 for all vaccination diagnoses.
For individuals with MIS and COVID-19, assign code U07. 1, COVID-19, as the principal/first-listed diagnosis and assign code M35. 81 as an additional diagnosis.

The Z23 code includes the following note: “Code first any routine childhood examination.” Therefore, when you provide immunizations in conjunction with a well-child visit, a code for routine child health examination should be reported first, followed by Z23 for any immunizations. This is similar to ICD-9 rules.
Z23 may be used as a primary diagnosis for immunizations in the OP and physician setting.
encounter for a vaccinationCode Z23 is used to indicate any encounter for a vaccination. The procedure codes are used to identify the type of the immunization given and how it was administered.
