A19 vs R76.1
A19 (Miliary tuberculosis) compared with R76.1 (Nonspecific reaction to test for tuberculosis), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. A19 carries an Excludes1 note covering R76.1: “nonspecific reaction to test for tuberculosis without active tuberculosis (R76.1-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
