About the R76 Code Range
These are abnormal immune-related findings in serum from a blood examination without a diagnosis.
R76.0 identifies a high antibody titer. R76.1 groups nonspecific tuberculosis test reactions. Its subdivisions distinguish a skin test from a measurement of the immune response to a tuberculosis antigen, both without active tuberculosis.
R76.8 groups other specified findings. It separates abnormal rheumatoid factor and anti-citrullinated protein antibody findings without rheumatoid arthritis from other specified findings. R76.9 identifies an unspecified finding.
FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, deleted R76.8.
