About R76.1
R76.1 is the ICD-10-CM diagnosis code for nonspecific reaction to test for tuberculosis. It belongs to category R76 (other abnormal immunological findings in serum), block R70-R79 (abnormal findings on examination of blood, without diagnosis) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
Within R76 (other abnormal immunological findings in serum), R76.1 is specifically for nonspecific reaction to test for tuberculosis. Related codes cover raised antibody titer (R76.0), other specified abnormal immunological findings in serum (R76.8) and abnormal immunological finding in serum, unspecified (R76.9).
To report this condition, pick the subcode that matches the documentation: R76.11 (tuberculosis) and R76.12 (tuberculosis).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
